Cement migration after THR. A comparison of charnley elite and exeter femoral stems using RSA. (1/1009)

Studies using roentgen stereophotogrammetric analysis (RSA) have shown that the femoral components of cemented total hip replacements (THR) migrate distally relative to the bone, but it is not clear whether this occurs at the cement-implant or the cement-bone interface or within the cement mantle. Our aim was to determine where this migration occurred, since this has important implications for the way in which implants function and fail. Using RSA we compared for two years the migration of the tip of the stem with that of the cement restrictor for two different designs of THR, the Exeter and Charnley Elite. We have assumed that if the cement restrictor migrates, then at least part of the cement mantle also migrates. Our results have shown that the Exeter migrates distally three times faster than the Charnley Elite and at different interfaces. With the Exeter migration was at the cement-implant interface whereas with the Charnley Elite there was migration at both the cement-bone and the cement-implant interfaces.  (+info)

Induction of macrophage C-C chemokine expression by titanium alloy and bone cement particles. (2/1009)

Particulate wear debris is associated with periprosthetic inflammation and loosening in total joint arthroplasty. We tested the effects of titanium alloy (Ti-alloy) and PMMA particles on monocyte/macrophage expression of the C-C chemokines, monocyte chemoattractant protein-1 (MCP-1), monocyte inflammatory protein-1 alpha (MIP-1alpha), and regulated upon activation normal T expressed and secreted protein (RANTES). Periprosthetic granulomatous tissue was analysed for expression of macrophage chemokines by immunohistochemistry. Chemokine expression in human monocytes/macrophages exposed to Ti-alloy and PMMA particles in vitro was determined by RT-PCR, ELISA and monocyte migration. We observed MCP-1 and MIP-1alpha expression in all tissue samples from failed arthroplasties. Ti-alloy and PMMA particles increased expression of MCP-1 and MIP-1alpha in macrophages in vitro in a dose- and time-dependent manner whereas RANTES was not detected. mRNA signal levels for MCP-1 and MIP-1alpha were also observed in cells after exposure to particles. Monocyte migration was stimulated by culture medium collected from macrophages exposed to Ti-alloy and PMMA particles. Antibodies to MCP-1 and MIP-1alpha inhibited chemotactic activity of the culture medium samples. Release of C-C chemokines by macrophages in response to wear particles may contribute to chronic inflammation at the bone-implant interface in total joint arthroplasty.  (+info)

The inadequacy of standard radiographs in detecting flaws in the cement mantle. (3/1009)

Radiological assessment of the cement mantle is used routinely to determine the outcome of total hip replacement. We performed a simulated replacement arthroplasty on cadaver femora and took standard postoperative radiographs. The femora were then sectioned into 7 mm slices starting at the calcar, and high-resolution faxitron radiographs were taken of these sections. Analysis of the faxitron images showed that defects in the cement mantle were observed up to 100 times more frequently than on the standard films. We therefore encourage the search for a better technique in assessing the cement mantle.  (+info)

Total knee replacement: should it be cemented or hybrid? (4/1009)

OBJECTIVE: To compare the complication rates associated with total knee arthroplasty against the types of fixation (hybrid or cemented), using a single total knee design (the anatomic modular knee [AMK] prosthesis). DESIGN: A prospective, nonrandomized, controlled trial. SETTING: University Hospital in London, Ont., a tertiary care teaching centre. PATIENTS: Two groups made up of 484 knees in 395 patients (89 bilateral). INTERVENTIONS: In 260 knees a hybrid configuration (cemented tibia and noncemented femur) was used (group 1). In 224 knees the femoral and tibial components were cemented (group 2). All patellae were cemented in both groups. MAIN OUTCOME MEASURES: Clinical results were assessed by The Knee Society Clinical Rating Scores at 3 months, 6 months and yearly intervals. Radiographic results were determined by 3-foot standing radiographs and at each follow-up visit standing knee radiographs, lateral and skyline views. Radiographs were analysed for alignment, presence or absence of radiolucent lines or changes in the position of the implant. All reoperations and nonoperative complications were recorded. RESULTS: At an average follow-up of 4.8 years, 8 knees (1.6%) required reoperation. An analysis of the complications leading to reoperation demonstrated no difference between the 2 groups. CONCLUSIONS: There was no difference in outcome whether the femoral component was cemented or not. Medium-term results of the AMK are excellent with a very low reoperation rate.  (+info)

Massive pelvic and femoral pseudotumoral osteolysis secondary to an uncemented total hip arthroplasty. (5/1009)

A 51 year-old man developed an extensive osteolytic response to wear debris in an uncemented porous-coated total hip arthroplasty, with metal/polyethylene interface, which had been implanted eighteen years previously. This reaction, which involved the upper femur and the ilium, produced a mass which compressed the pelvic viscera.  (+info)

Pulmonary embolism caused by acrylic cement: a rare complication of percutaneous vertebroplasty. (6/1009)

A pulmonary embolus of acrylic cement was present in a 41-year-old woman with Langerhans' cell vertebral histiocytosis (LCH) after percutaneous vertebroplasty. Chest radiograph and CT confirmed pulmonary infarction and the presence of cement in the pulmonary arteries. She was treated with anticoagulants, and responded favorably. This rare complication occurred because perivertebral venous migration was not recognized during vertebroplasty. Adequate preparation of cement and biplane fluoroscopy are recommended for vertebroplasty.  (+info)

More failures of uncemented acetabular screw-rings than of cemented polyethylene cups in total hip arthroplasties. (7/1009)

The results of 498 total hip arthroplasties were prospectively studied. In 329 patients a cemented acetabular polyethylene cup was inserted. In 169 patients a threaded socket without cement was introduced. Follow-up ranged from 6 to 8 years and follow-up rate was over 90%. Of the 169 threaded sockets 8 required revision (4.7%), and 3 acetabular components were seen to be loose on X-ray. Of the cemented cups, only 2 (0.6%) required revision and none were considered loose on X-ray.  (+info)

Mid-term migration of a cemented total hip replacement assessed by radiostereometric analysis. (8/1009)

We have previously reported the short-term migration of cemented Hinek femoral components using radiostereometric analysis (RSA). We now report the mid-term migration. During the first 2 years after implantation the prosthesis subsided into varus and rotated internally. Between years 3 and 8 the prosthesis continued to rotate internally with the head moving posteriorly (0.07 mm/year, P=0.004). It also continued to fall into varus with the tip moving laterally (0.07 mm/year, P=0.04). The head (0.06 mm/year, P<0.0001), shoulder (0.04 mm/year, P=0.0001) and tip (0.04 mm/year, P=0.001) continued to migrate distally. There were two cases of failure due to aseptic loosening during the follow-up period. During the second year both of these had posterior head migration, which was abnormally rapid (>2 SD from the mean). We have demonstrated that a cemented implant has slow but significant levels of migration and rotation for at least 8 years after implantation. Our study confirms that implants with abnormally rapid posterior head migration during the second year are likely to fail.  (+info)

Bone-cement interface of the glenoid component: stress analysis for varying cement thickness - InfoscienceBone-cement interface of the glenoid component: stress analysis for varying cement thickness - Infoscience
BACKGROUND: Although shoulder arthroplasty is an accepted treatment for osteoarthritis, loosening of the glenoid component, which mainly occurs at the bone-cement interface, remains a major concern. Presently, the mechanical effect of the cement mantel thickness on the bone-cement interface is still unclear. METHODS: Finite element analysis of a prosthetic scapula was used to evaluate the effect of cement thickness on stresses and micromotions at the bone-cement interface. The glenoid component was all-polyethylene, keeled and flat back. Cement mantel thickness was gradually increased from 0.5 to 2.0 mm. Two glenohumeral contact forces were applied: concentric and eccentric. Two extreme cases were considered for the bone-cement interface: bonded and debonded. FINDINGS: Within cement, stress increased as cement thickness decreased, reaching the fatigue limit below 1.0 mm. Bone stress was below its ultimate strength and was minimum between 1.0 and 1.5mm. Interface stress was close to the interface

The effect of antibiotic-loaded bone cement on risk of revision following hip and knee arthroplasty. - NextBio article
This study aimed to compare the effect of antibiotic-loaded bone cement (ALBC) versus plain bone cement (PBC) on revision rates for periprosthetic joint infection (PJI) and all-cause revisions following primary elective total hip arthroplasty (THA) and total knee arthroplasty (TKA). MEDLINE, Embase, Web of Science, and Cochrane databases were systematically searched for studies comparing ALBC versus PBC, reporting on revision rates for PJI or all-cause revision following primary elective THA or TKA. A random-effects meta-analysis was performed. The study was registered in the International Prospective Register of Systematic Reviews (PROSPERO ID CRD42018107691). Nine studies and one registry report were identified, enabling the inclusion of 371,977 THA and 671,246 TKA. Pooled analysis for THA demonstrated ALBC was protective against revision for PJI compared with PBC (relative risk (RR) 0.66, 95% confidence interval (CI) 0.56 to 0.77; p < 0.001), however, no differences were seen for all-cause ...

Some failure modes of four clinical bone cements - Lancaster EPrintsSome failure modes of four clinical bone cements - Lancaster EPrints
The fracture or failure behaviours of four commercial acrylic-based bone cements have been examined in tensile, bending and compression modes, and their mechanical properties are reviewed. It was found that Palacos R-40 bone cement had high radiopaque agent concentration, with high surface hardness. It exhibited a much lower bending strength and bending modulus compared with the other three bone cements (CMW1, CMW2000 and Simplex P). The textures of tensile fracture surfaces produced were similar for the four bone cements studied. The fracture surface was fragmented by crevices, which developed through the matrix and around large undissolved polymethylmethacrylate (PMMA) beads. Three bands with different features existed on the bending fracture surfaces, with an abrupt transition between them. It appears that the agglomerates of zirconium dioxide particles are implicated in Palacos R-40 bone cement fracture surface. The examination of compressive failed specimens revealed that a yielded crack ...

Device for Mixing and Dispensing Bone Cement - Patent applicationDevice for Mixing and Dispensing Bone Cement - Patent application
0003]Polymethylmethacrylate bone cements can be mixed in suitable mixing beakers with spatulas by mixing the cement powder with the monomer liquid. This procedure is disadvantageous in that inclusions of air may be present in the cement dough thus formed and may later cause destabilization of the bone cement. For this reason, it is preferable to mix bone cement powder with the monomer liquid in vacuum mixing systems, since mixing in a vacuum removes inclusions of air from the cement dough all but completely and attains optimal cement quality (Breusch, S. J. et al., Der Stand der Zementiertechnik in Deutschland [The State of Cementing Technology in Germany], Z. Orthop., 137: 101-07 (1999)). Bone cements mixed in a vacuum have substantially lower porosity and thus show improved mechanical properties. A large number of vacuum cementing systems have been disclosed of which the following shall be named for exemplary purposes: U.S. Pat. Nos. 6,033,105; 5,624,184; 4,671,263; 4,973,168; 5,100,241; ...

We studied fluid flow at the stem-cement interface of bonded and debonded, polished and rough model femoral components. In a first series of experiments, fluid flow along the interface between bone cement and well-fixed model femoral components, differing in surface finish, and in shape, was measured. Fluid migration along the bone-cement interface of rough stems (Ra 3 microm) was greater than that on polished stems (p | 0.001). This was true of cylindrical and conical tapered stems. On stems with the same surface finish, shape did not influence fluid migration. In a second series of experiments, fluid flow along the stem-cement interface of 5 highly polished and 10 rough-finished (5 of Ra approximately 1.5 microm and 5 of Ra approximately 3 microm), debonded, tapered circular stems was measured. None of the rough stems could prevent fluid flow along the stem-cement interface. Polished tapered stems sealed the interface and, after 48 hrs of continuous pressure, no fluid flow was observed.

Two-stage exchange with antibiotic-loaded bone cement spacers remains the gold standard for chronic periprosthetic joint infection (PJI). Rifampicin is highly efficient on stationary-phase staphylococci in biofilm; however, its addition to PMMA to manufacture spacers prevents polymerization and reduces mechanical properties. Isolation of rifampicin during polymerization by microencapsulation could allow manufacturing rifampicin-loaded bone cement maintaining elution and mechanical properties. Microcapsules of rifampicin with alginate, polyhydroxybutyratehydroxyvalerate (PHBV), ethylcellulose and stearic acid (SA) were synthesized. Alginate and PHBV microcapsules were added to bone cement and elution, compression, bending, hardness, setting time and microbiological tests were performed. Repeated measures ANOVA and Bonferroni post-hoc test were performed, considering a p,0.05 as statistical significance. Bone cement specimens containing alginate microcapsules eluted more rifampicin than PHBV ...

Effect of restraint on the creep behavior of clinical bone cement - Lancaster EPrintsEffect of restraint on the creep behavior of clinical bone cement - Lancaster EPrints
Bone cement creep behavior was studied using commercial available clinical bone cement. Creep deformation was measured using a micrometer with a resolution of 1 μm. It was demonstrated that the restraint has a very strong effect on the creep of bone cement, half-restrained specimens creep more than that of fully restrained specimens. The creep of the investigated bone cement increased with the dynamic loading cycles, and two creep stages, a high initial creep rate followed by a steady creep stage, can be identified. The relationship between the creep deformation and the loading cycles was expressed by a single logarithmic model.. ...

The mechanical effects of different levels of cement penetration at the cement-bone interface.The mechanical effects of different levels of cement penetration at the cement-bone interface.
The mechanical effects of varying the depth of cement penetration in the cement-bone interface were investigated using finite element analysis (FEA) and validated using companion experimental data. Two FEA models of the cement-bone interface were created from micro-computed tomography data and the penetration of cement into the bone was varied over six levels each. The FEA models, consisting of the interdigitated cement-bone constructs with friction between cement and bone, were loaded to failure in tension and in shear. The cement and bone elements had provision for crack formation due to excessive stress. The interfacial strength showed a strong relationship with the average interdigitation (r(2)=0.97 and r(2)=0.93 in tension and shear, respectively). Also, the interface strength was strongly related with the contact area (r(2)=0.98 and r(2)=0.95 in tension and shear, respectively). The FEA results compared favorably to the stiffness-strength relationships determined experimentally. Overall, ...

A hybrid zinc-calcium-silicate polyalkenoate bone cementA hybrid zinc-calcium-silicate polyalkenoate bone cement
A novel bone cement composed of sintered zinc-calcium-silicate phosphate and hybrid polyalkenoates has been developed. Synthesis and formulation of glass fillers, monomers and polymers as well as formulation of the cement were described. The effects of sintering, polymer content, glass powder/polymer liquid (P/L) ratio and comonomer on compressive strength (CS) and curing time (CT) were investigated. The effects of P/L ratio and comonomers on shrinkage as well as exotherm were also studied. Results show that the experimental cement was 61% higher in CS, 10% lower in diametral tensile strength, 35% lower in flexural strength, 62% less in exotherm, and 68% less in shrinkage, compared to conventional polymethylmethacrylate cement. With increasing polymer content and P/L ratio in the cement formulation CS of the cement increased but CT decreased. Curing time, shrinkage and exotherm of the cement decreased with increasing P/L ratio. It appears that this novel cement may be a potential candidate for ...

A custom made femoral component is made using the femoral cavity and an internal latex envelope as the mold. After the femoral cavity is worked into a roughly conical shape, an internal latex envelope is inserted into the cavity and filled with bone cement. An endoskeleton is inserted down the femoral cavity into the bone cement. The internal latex mold conforms to the shape of the cavity and an accurate negative of the cavity is created as the bone cement solidifies. The femoral component is pulled from the cavity and the internal latex envelope is peeled off the component. All traces of the internal latex envelope is removed from the femoral cavity and component. The femoral component is then reimplanted.

US4285071A - Method of securing a prosthesis using cement spacers - Google Patents
A prosthetic cement spacer for controlling the thickness of cement applied between a prosthetic insert and a support member, such as an acetabulum, includes a generally cylindrical standoff body portion fabricated from acrylic bone cement and a pointed wire concentric with said standoff body and outwardly extending from one end a sufficient length to anchor into the acetabulum bone surface. The method of use of these prosthetic cement spacers involves preparation of the acetabulum so that there is sufficient clearance space for the prosthetic cement spacers and then to insert the pointed wires into the acetabulum bone surface in an equilateral triangular arrangement thereby providing three points of contact for the prosthetic insert, such as an acetabular cup. By selecting three prosthetic cement spacers all having substantially the same standoff body height, the clearance region between the acetabulum bone surface and the acetabular cup is controlled and provides a uniform cement thickness

The standard cementing technique for total hip and knee arthroplasty (THA, TKA) was modified by interposing osteoconductive porous polycrystalline hydroxyapatite (HA) granules at the cement-bone interface to augment cement-bone bonding. Twenty-one specimens from the acetabulum and two specimens from the femur containing well-fixed bone-cement interface were retrieved five months to twenty-two years after THA and TKA with an interface bioactive bone cement technique. Histological findings were evaluated in terms of the retrieved sites, the interval between index operation and revision, patient age at retrieval and bone pathology. Dense bone ingrowth was observed in all specimens retrieved from the superior wall of the acetabulum. Cancellous bone ingrowth was observed in specimens retrieved from the infero-medial wall of the acetabulum. Connective tissue interposition and osteolysis were observed at the sites where hydroxyapatite granules were absent. Findings of bone ingrowth for the HA ...

2018 Trans Tech Publications, Switzerland. In this research, mechanical properties of bone cement containing micro- and nano-hydroxyapatite (HAp) particles were studied. The bone cement was prepared from mixing between polymethyl methacrylate (PMMA) and methyl methacrylate (MMA). Hydroxyapatite powder was prepared from bovine bone. The bone was heated in hot water at 200oc for the elimination of tissue, after which the bone was dried and calcined at 800oc for 3 hrs. The calcined bone then was crushed into powder and ball-milled for 24 hrs. The micro-HAp particle was then obtained. The micro particles were then further milled employing the Vibro-milling machine for 2 hrs. The micro- and nano- HAp sizes are about 0.5 µm and 140 nm, respectively. The both size powders were treated with γ-methacrylic-propyl-tri-methoxy silane. The acetic acid was added to control the pH of the solution, until it reached 2.9 before they were mixed into the bone cement with equally wt%. The mixture was casted using ...

Two-stage revision arthroplasty is today considered as the gold standard for control of chronic deep prosthetic infection. Although the revision arthroplasty should only be considered when infection is eliminated, the diagnosis of residual infection prior to the revision remains a challenging problem. We evaluated triple-phase bone scintigraphy as a useful diagnostic test for the detection of residual infection around the antibiotic-impregnated cement spacer in patients waiting for the second-stage revision hip or knee arthroplasty. Increased uptake of radioisotope in all three phases was considered positive for infection. The final diagnosis was based on histopathological results in addition to microbiologic examinations of surgical specimens. Histopathological examination showed positive in 17 and negative in 13 out of 30 examinations. Among 17 samples positive for histopathology, there were only 4 samples positive for bacterial culture. All samples negative for histopathology showed negative for

Filling high modulus PMMA increases the modulus of filled verterbra, increasing the risk of fracture in the adjacent vertebra. On the other hand, in porous PMMA bone cements, wear particle generation and deterioration of mechanical performance are the major drawbacks. This study adopts a new approach by utilizing linoleic acid coated strontium substituted hydroxyapatite nanoparticle (Sr-5 HA) and linoleic acid as plasticizer reducing bone cements modulus with minimal impact on its strength. We determined the compressive strength (UCS) and modulus (Ec), hydrophobicity, injectability, in vitro bioactivity and biocompatibility of this bone cement at different filler and linoleic acid loading. At 20 wt % Sr5-HA incorporation, UCS and Ec were reduced from 63 ± 2 MPa, 2142 ± 129 MPa to 58 ± 2 MPa, 1785 ± 64 MPa, respectively. UCS and Ec were ...

Cement mantles were moulded in a manner simulating clinical practice for cemented hip replacement. During polymerisation, the temperature was monitored. Specimens of cement extracted from the mantles underwent bending or fatigue tests, and were examined for porosity. Pre-heating the stem alone significantly increased the mean temperature values measured within the mantle (+14.2°C) (p ,0.001) and reduced the mean curing time (-1.5 min) (p ,0.001). The addition of vacuum mixing modulated the mean rise in the temperature of polymerisation to 11°C and reduced the mean duration of the ...

Hip Replacement - Max India Medicare
Total Hip Replacement: With Acrylic Cement Fixation A cemented prosthesis is designed to have a layer of bone cement, typically an acrylic polymer called polymethylmethacrylate (PMMA), in between the patients natural bone and the prosthetic joint component. Bone cement allows a surgeon to affix prosthetic joint components to a bone that is slightly porous from osteoporosis. A small amount of antibiotic material can be added to the bone cement, helping to decrease the risk of post-surgical infection.. Total Hip Replacement: Without Cement Fixation. Also called as press-fit prosthesis it is a surgical procedure in which bone is attached to a metal implant if the surface of the metal has certain topography. This process is called porous ingrowth or osseointegration. The bone must be prepared precisely for these devices because close apposition to bone is necessary for bone to grow up to the smooth surface (osteointegration) or into the pores of the porous surfaces. Surface coatings, such as ...

Micromechanics of postmortem-retrieved cement-bone interfacesMicromechanics of postmortem-retrieved cement-bone interfaces
The cement-bone interface plays an important role in load transfer between cemented implant systems and adjacent bone, but little is known about the micromechanical behavior of this interface following in vivo service. Small samples of postmortem-retrieved cement-bone specimens from cemented total hip replacements were prepared and mechanically loaded to determine the response to tensile and compressive loading. The morphology of the cement-bone interface was quantified using a CT-based stereology approach. Laboratoryprepared specimens were used to represent immediate postoperative conditions for comparison. The stiffness and strength of the cement - bone interface from postmortem retrievals was much lower than that measured from laboratory-prepared specimens. The cement-bone interfaces from postmortem retrievals were very compliant (under tension and compression) and had a very low tensile strength (0.21±0.32 MPa). A linear regression model, including interface contact fraction and ...

PURPOSE The usual treatment in cervical nerve root compression syndrome is the ventral fusion with bone cement. We examined the influence of this interponate on the postoperative changes of the cervical spine. MATERIALS AND METHODS 33 patients were followed-up postoperatively over 6 months, who were treated with 39 ventral fusions because of cervical myelopathy. The lateral view of the cervical spine was used to measure the size of the bone cement interponate, the height of the intervertebral body space and the angle of both vertebral bodies. RESULTS There was no change on the size of the interponate. Postoperatively there was a slight enlargement of the intervertebral body space. During further follow-up examinations there was a decrease to the preoperative size because of the destruction of the endplates. Similar to this observation, there was a change of the angle in the operated segment. First there was a decrease of the angle, later an increase. 6 months postoperatively the preoperatively

Fixation
Robust fixation of implants is very important as in younger patients these joints are required to last 20 to 30 years or even more. Charnley used a material called acrylic bone cement to fix the implants to the bone which had previously been used by dental surgeons and this material can still be very effective. The bone cement is made by mixing a fluid component with a powder component and the liquid becomes doughy within a few minutes, becomes like putty within about four of five minutes and most cements set around the ten minute mark. The exact setting characteristics of the cement do differ somewhat depending on the different types of materials used in the bone cement. So some bone cements can set quite quickly in five minutes and others can set over a longer period over 15 minutes. Once set the cement is very strong under compression and forms a very good bond between the prosthesis whether it be the femoral component or acetabular component or indeed the femoral component of a knee ...

US20060085008A1 - Device for injecting bone cement - Google Patents
In a device for injecting bone cement, the discharge direction of the bone cement after insertion of the cannula should be controllable in a certain region. This is made possible through a radial exit aperture ( 5 ) which is provided on the front end of the cannula ( 3 ). Since the cannula is inserted with the aid of a guide wire ( 1 ), it has an orifice ( 4 ) on its front end, which orifice must be closed off by means of a ball ( 15 ) prior to the injection. A plunger serves to insert the ball ( 15 ). So that the situation of the radial aperture ( 5 ) is known at all times, even with inserted cannula, the handle ( 17 ) of the cannula has an asymmetrical shape.

TY - JOUR. T1 - Fatigue crack propagation in polymethylmethacrylate bone cements. AU - Wright, Timothy M.. AU - Robinson, Raymond P.. PY - 1982/9/1. Y1 - 1982/9/1. N2 - The fatigue crack propagation behaviour of a conventional polymethylmethacrylate (PMMA) bone cement was examined and compared with those of a low-viscosity PMMA cement and a carbon-fibre reinforced PMMA cement. The low-viscosity PMMA cement, developed for use in cement pressurization systems, did not differ significantly from conventional PMMA cement in its crack propagation behaviour. The carbon-fibre reinforced PMMA cement exhibited crack propagation rates which were approximately an order of magnitude less than those of conventional PMMA at the same range of stress intensity factor. Fractography of the test specimens revealed separation around prepolymerized PMMA beads and void formation around barium sulphate particles. Examination of carbon reinforced PMMA specimens showed poor mechanical bonding between the carbon fibres ...

A novel liposomal drug delivery system for PMMA bone cements -ORCAA novel liposomal drug delivery system for PMMA bone cements -ORCA
The population in developed countries is ageing and the number of people experiencing joint-related conditions, such as osteoarthritis, is expected to increase. Joint replacements are currently the most effective treatment for severe joint conditions and although many of these procedures are successful, infection developing after the procedure is still an issue, requiring complex and expensive revisions. Whilst incorporating a powdered antibiotic within the bone cement can reduce infection rates, the powder frequently agglomerates, resulting in poor antibiotic release characteristics and compromised mechanical performance of the cement. To overcome these issues, a novel delivery system consisting of antibiotic-loaded nano-sized liposomes was developed for inclusion into polymethyl methacrylate (PMMA) bone cement. This system was tested in a commercial cement (Palacos R) and consistently delivered a higher percentage (22%) of the incorporated antibiotic when compared to the powdered antibiotic ...

Enhanced Osteointegration of Poly(Methylmethacrylate) Bone Cements by by Xu Cui, Chengcheng Huang et al.Enhanced Osteointegration of Poly(Methylmethacrylate) Bone Cements by by Xu Cui, Chengcheng Huang et al.
Although poly(methylmethacrylate) (PMMA) cements are widely used in orthopaedics, they have numerous drawbacks. This study aimed to improve their bioactivity and osseointegration by incorporating strontium-containing borate bioactive glass (SrBG) as the reinforcement phase and bioactive filler of PMMA cement. The prepared SrBG/PMMA composite cements showed significantly decreased polymerization temperature when compared with PMMA and retained properties of appropriate setting time and high mechanical strength. The bioactivity of SrBG/PMMA composite cements was confirmed in vitro, evidenced by ion release (Ca, P, B and Sr) from SrBG particles. The cellular responses of MC3T3-E1 cells in vitro demonstrated that SrBG incorporation could promote adhesion, migration, proliferation and collagen secretion of cells. Furthermore, our in vivo investigation revealed that SrBG/PMMA composite cements presented better osseointegration than PMMA bone cement. SrBG in the composite cement could stimulate new-bone

Biocompatibility and resorption of a radiopaque premixed calcium phosphate cementBiocompatibility and resorption of a radiopaque premixed calcium phosphate cement
Calcium phosphate cements are used in medicine to fill bone defects or give support to screws and plates in fracture fixation. The cements are formed via mixing a powder with water and the mixture harden through a dissolution-precipitation reaction. Today the cement mixing is performed in the operating room and consists of several complicated steps that need to be performed under sterile conditions. This renders the mixing a risk factor, potentially leading to harm for the patient e.g. unsatisfactory healing or infection. To reduce this risk, premixed cements have been developed using glycerol as mixing liquid. The premixed cement sets when it is exposed to body liquids. Therefore, premixed cement can be delivered to the operating room in prefilled syringes ready for use, thus eliminating the mixing step.. The aim of this thesis is to describe differences between premixed and water-mixed cements and their advantages and drawbacks. The differences will be discussed based on results obtained from ...

Pre-revision radiographs showed the presence of both full and partial RLL. On contact radiographs of 5 mm thick sections of the interface the total percentage of radiolucency ranged from 0 to 90% between patients. There was no consistent pattern for the distribution of radiolucency. Histological assessment demonstrated that under every tibial component there were areas where there was direct contact and interdigitation between bone and cement. The amount of direct bone-cement contact was between 19% and 95% of the tibial tray surface area. The remaining tissue was mainly fibrocartilage but there was also fibrous tissue. The presence of radiolucency was strongly inversely correlated with the percentage of cement-bone contact ...

Calcium phosphate cements (CPC) are well-established bone replacement materials that have been used in dentistry and orthopedics for more than 25 years. The monitoring of bone cements and the associated healing processes in the human body is difficult and so far has often been achieved using cytotoxic X-ray contrast agent additives. These additives have a negative effect on the mechanical properties and setting time of the bone cement. In this paper, we present a novel approach to prepare contrastive CPC by the incorporation of luminescent Eu3+-doped hydroxyapatite (Eu:HAp) nanoparticles. Eu-doped CPC (Eu:CPC) exhibited enhanced mechanical properties compared to pure CPC. Furthermore, the red photoluminescence of Eu:CPC may allow the observation of CPC-related healing processes without the use of harmful ionizing radiation.

Multiple characterization study on porosity and pore structure of calcium phosphate cementsMultiple characterization study on porosity and pore structure of calcium phosphate cements
Characterization of the intricate pore structure of calcium phosphate cements is a key step to successfully link the structural properties of these synthetic bone grafts with their most relevant properties, such as in vitro or in vivo behaviour, drug loading and release properties, or degradation over time. This is a challenging task due to the wide range of pore sizes in calcium phosphate cements, compared to most other ceramic biomaterials. This work provides a critical assessment of three different techniques based on different physical phenomena, namely mercury intrusion porosimetry (MIP), Nitrogen sorption, and thermoporometry (TPM) for the detailed characterization of four calcium phosphate cements with different textural properties in terms of total porosity, pore size distribution (PSD), and pore entrance size distribution (PESD). MIP covers a much wider size range than TPM and Nitrogen sorption, offering more comprehensive information at the micrometer level. TPM, and especially ...

Radio-opaque agents in bone cement increase bone resorption. - Nuffield Department of Orthopaedics, Rheumatology and...
A heavy infiltrate of foreign-body macrophages is commonly seen in the fibrous membrane which surrounds an aseptically loose cemented implant. This is in response to particles of polymethylmethacrylate (PMMA) bone cement and other biomaterials. We have previously shown that monocytes and macrophages responding to particles of bone cement are capable of differentiating into osteoclastic cells which resorb bone. To determine whether the radio-opaque additives barium sulphate (BaSO4) and zirconium dioxide (ZrO2) influence this process, particles of PMMA with and without these agents were added to mouse monocytes and cocultured with osteoblast-like cells on bone slices. Osteoclast differentiation, as shown by the presence of the osteoclast-associated enzyme tartrate-resistant acid phosphatase (TRAP) and lacunar bone resorption, was observed in all cocultures. The addition of PMMA alone to these cocultures caused no increase in TRAP expression or bone resorption relative to control cocultures. Adding PMMA

This study aims to evaluate in vitro the release properties and biological behavior of original compositions of strontium (Sr)-loaded bone mineral cements. Strontium was introduced into vaterite CaCO3-dicalcium phosphate dihydrate cement via two routes: as SrCO3 in the solid phase (SrS cements), and as SrCl2 dissolved in the liquid phase (SrL cements), leading to different cement compositions after setting. Complementary analytical techniques implemented to thoroughly investigate the release/dissolution mechanism of Sr-loaded cements at pH 7.4 and 37°C during 3 weeks revealed a sustained release of Sr and a centripetal dissolution of the more soluble phase (vaterite) limited by a diffusion process. In all cases, the initial burst of the Ca and Sr release (highest for the SrL cements) that occurred over 48 h did not have a significant effect on the expression of bone markers (alkaline phosphatase, osteocalcin), the levels of which remained overexpressed after 15 days of culture with human ...

Acrylic glass - wikidocAcrylic glass - wikidoc
In orthopaedics, PMMA bone cement is used to affix implants and to remodel lost bone. It is supplied as a powder with liquid methyl methacrylate (MMA). When mixed these yield a dough-like cement that gradually hardens. Surgeons can judge the curing of the PMMA bone cement by pressing their thumb on it. Although PMMA is biologically compatible, MMA is considered to be an irritant and a possible carcinogen. PMMA has also been linked to cardiopulmonary events in the operating room due to hypotension. [8] Bone cement acts like a grout and not so much like a glue in arthroplasty. Although sticky, it primarily fills the spaces between the prosthesis and the bone preventing motion. It has a Youngs modulus between cancellous bone and cortical bone. Thus it is a load sharing entity in the body not causing bone resorption. [9] ...

Hydroxyapatite cement was investigated in situ for the reconstruction of juxta-articular defects. Polymethylmethacrylate is currently the most commonly used material for the reconstruction of bone defects following the exteriorization and curettage of aggressive benign tumors. In vitro, we compared the effects of hydroxyapatite cement and polymethylmethacrylate in restoring the stiffness of the subchondral plate in a caprine femoral defect model. Ten matched pairs of caprine femora underwent nondestructive compression testing normal to the load-bearing surface. A standardized subchondral defect 12 mm in diameter was created in the medial femoral condyle. Compression testing was repeated to determine the reduction in stiffness caused by the defect. Each femur from each pair was randomly assigned to one of two groups (n=9), and the defects were augmented with either polymethylmethacrylate or hydroxyapatite cement. After 12 hours, compression testing was repeated to determine the subchondral stiffness

After diagnosis of infection and informed consent, patients will be taken to the operating room. After anesthetization, patients will be randomized to either an articulating spacer or static spacer. Randomization will be performed by prepared opaque envelopes administered by a nonparticipant in the study. After a complete debridement of devitalized tissue, explantation of infected components and any associated cement, either an articulating or static spacer will be placed. All spacers will be formed using 3.0 g of Vancomycin and 1.0 g of Tobramycin for each 40 g packet of cement. Articulating spacers will be formed of antibiotic-impregnated cement using the Stage One system (Biomet, Warsaw, IN) sized to fit the endosteal and acetabular bone defect. Static spacers will be hand-made with a rod of antibiotic-impregnated cement and cement beads of sufficient quantity to fill the acetabulum..

Calcium Phosphate Bone Cements. By Erdem Şahin. Biomaterials utilized in biomedical applications are of various characteristics and cements are unique in their in situ, biomimetic formation ability. They present the most topographically complex surfaces that usually elicit a favorable cellular response for tissue regeneration. In addition their composition may provide an effective chemical gradient around the resorbing implant to induce desired cellular activity that leads to rapid wound healing and regeneration. These are the main reasons for many cement systems to function well in the body, especially as hard tissue replacements. The properties and the setting mechanisms of the clinically most relevant cement system, calcium phosphate cements have been elucidated in this chapter.. Part of the book: Cement Based Materials ...

custom forehead implants Archives - Plastic Surgeon | Dr. Barry L. Eppley, MDcustom forehead implants Archives - Plastic Surgeon | Dr. Barry L. Eppley, MD
Finally, I wonder how much my forehead can be protrude by surgery. You know I am Asian, and I want to make my forehead and brow bone protrude as much as a Caucasian, if its possible. I really want to know whether its possible or not.. A: I have done forehead and brow bone augmentation over my career by every conceivable method including PMMA and hydroxyapatite bone cements, prefrormed Medpor implants and, more recently, custom forehead and brow bone implants.. Each of these methods have their own distinct advantages and disadvantages…neither one is perfect. Bone cements are very good to use but they require a lot of intraoperative shaping, can be very expensive (HA cements) and can lead to frontal bossing/protrusions if the forehead and brow bones is brought too far forward. (as bone cements should not extend beyond the anterior temporal lines onto the tenporalis muscle fascia where they will not adhere and can lead to visible edging). To place them well, they require a long coronal incision ...

Why would cement porosity reduction be clinically irrelevant, while experimental data show the contrary.Why would cement porosity reduction be clinically irrelevant, while experimental data show the contrary.
Laboratory bench tests have shown that porosity reduction increases the fatigue life of bone cement specimens. Clinically, however, the effect porosity reduction is subject to debate. We hypothesized that the discrepancy between clinical and experimental findings is related to differences in the stress distribution, which is typically uniform in experimental test specimens, while stress concentrations exist in cement around hip implants. We simulated fatigue failure of cement in a finite element model of an experimental test specimen and of a transverse slice of a total hip arthroplasty with a sharp-cornered stem. Four levels of porosity were introduced. In the fatigue test specimen model, the fatigue life clearly was dependent on the level of porosity, while in the transverse slice model, the level of porosity had virtually no effect on failure of the cement mantle. The results of the simulations confirmed our hypothesis. In simulations of laboratory tests, pores clearly acted as crack ...

Laboratory confirmed polymethyl-methacrylate (Palacos)-hypersensitivity after cranioplasty - Zurich Open Repository and ArchiveLaboratory confirmed polymethyl-methacrylate (Palacos)-hypersensitivity after cranioplasty - Zurich Open Repository and Archive
Polymethyl-methacrylate (PMMA) as part of bone cement is a widely used material in the context of orthopaedic implants and also in cranioplasty. Although PMMA is characterised by excellent biocompatibility with low intrinsic toxicity and inflammatory activation, a minor portion of patients develop allergic reactions. We present the case of a 39-year-old woman with an increasing headache and a corresponding erythema over the parieto-occipital cranioplasty, which was performed 42 days prior using a PMMA compound. A patch test specific for bone cement components confirmed the diagnosis of a PMMA delayed-type hypersensitivity reaction. The prevalence of allergic reactions to bone cement components are known to vary from between 0.6% and 1.6%, however no adequate, pre-interventional diagnostic tool is currently available. Therefore, physicians are required to consider this differential diagnosis even after an extremely delayed onset of symptoms. This case describes the first ever-reported case in the ...
