Radiological factors influencing femoral and acetabular failure in cemented Charnley total hip arthroplasties. (1/386)

We have made a retrospective review of 185 cemented Charnley total hip arthroplasties performed between 1970 and 1974 to determine the relationships between radiological variables and failure of the femoral and acetabular components. We measured the acetabular wear, the orientation of the cup, the thickness and consistency of acetabular and femoral cement mantles, radiolucency and femoral alignment. The mean follow-up was for 11.7 years. Femoral loosening was demonstrable radiologically in 15 hips (8.1%), ten (5.4%) of which were revised during the period of follow-up. Only when the first postoperative radiograph showed a thin cement mantle in Gruen zone 5 was there a significant association with failure of the femoral component. There were 12 loose acetabular components (6.5%), nine (4.8%) of which were revised. When the initial radiograph after operation showed radiolucency in DeLee and Charnley zone 1, the incidence of acetabular loosening was 28.21%. If such radiolucency was not present, the incidence of acetabular loosening was only 0.69%. Our findings emphasise the importance of careful cementing.  (+info)

Influence of composite inlay/onlay thickness on hardening of dual-cured resin cements. (2/386)

This investigation evaluated the effect of resin composite inlay/onlay thickness on the hardness of a group of eight dual-cure resin-based cements. Fourteen disc specimens measuring 6 mm in diameter and 2.5 mm thick were prepared from each of eight dual-cure cements: Adherence, Choice, Duolink, Enforce, Lute-It, Nexus, Resinomer and Variolink. Two specimens from each material were directly light-cured while the remainder of the specimens were light-cured through resin composite spacers varying in thickness from 1 mm to 6 mm. Curing through the spacers always resulted in a decrease in the Knoop hardness number. For some cements, hardness values were reduced by 50% or more when the resin composite spacer thickness was 4 mm or greater even when measurements were made one week after dual-curing. Low hardness values indicate the presence of a weak chemical-curing mechanism that may compromise cement quality in areas of the cavity not readily accessible to the curing light.  (+info)

A survey of the delegation of orthodontic tasks and the training of chairside support staff in 22 European countries. (3/386)

This paper reports on a survey which was undertaken to investigate the delegation of orthodontic tasks and the training of chairside support staff in Europe. Two questionnaires were posted to all members of the EURO-QUAL BIOMED II project together with an explanatory letter. The first dealt with the delegation of nine clinical tasks during orthodontic treatment. The second with the types of chairside assistant employed in each country and the training that they are given. Completed questionnaires, which were subsequently validated, were returned by orthodontists from 22 countries. They indicated that there was no delegation of clinical tasks in six of the 22 countries and delegation of all nine tasks in five countries. The most commonly delegated tasks were taking radiographs (in 14 of the 22 countries) and taking impressions (in 13 of the 22 countries). The least commonly delegated tasks were cementing bands (in five of the 22 countries) and trying on bands (in six of the 22 countries). Seven of the 22 countries provided chairside assistants with training in some clinical orthodontic tasks. Eighteen of the 22 countries provided general training for chairside assistants and offered a qualification for chairside assistants. Four of these 18 countries reported that they only employed qualified chairside assistants. Of the four countries which reported that they did not provide a qualification for chairside assistants, two indicated that they employed chairside assistants with no formal training and two that they did not employ chairside assistants. It was concluded that there were wide variations within Europe as far as the training and employment of chairside assistants, with or without formal qualifications, and in the delegation of clinical orthodontic tasks to auxiliaries was concerned.  (+info)

Restoration of endodontically treated teeth with carbon fibre posts--a prospective study. (4/386)

BACKGROUND: A prospective study was started in 1995 to evaluate the success of carbon fibre reinforced epoxy resin (CFRR) posts used to restore endodontically treated teeth. All the teeth in the study had lost more than 50% of their coronal structure. METHODS: Fifty-nine carbon fibre Composiposts cemented with Metabond and built up with Core Paste cores were placed into the teeth of 47 patients. Each tooth received a full-coverage restoration (porcelain fused to metal crown) and was followed for 6.7-45.4 months (average = 28.0 months, standard deviation = 10.7). RESULTS: Results for 52 teeth in 42 patients were analyzed. There were no fractures. The overall failure rate was 7.7% and the cumulative survival rate was 89.6% at the end of the follow-up period. The only statistically significant finding (p = 0.04) was that posts in lower premolars were at higher risk of failure. CONCLUSION: CFRR posts are among the most predictable systems available today. CFRR posts in the upper anterior teeth are associated with a higher success rate and longer life than those placed in premolars, especially lower premolars. This study contributes to the growing body of evidence that supports the use of CFRR posts in the restoration of endodontically treated teeth.  (+info)

All-polyethylene versus metal-backed and stemmed tibial components in cemented total knee arthroplasty. A prospective, randomised RSA study. (5/386)

We studied the quality of fixation of the tibial component using radiostereometric analysis (RSA) in 40 patients who had undergone a cemented Freeman-Samuelson total knee arthroplasty. They were prospectively randomised to either a stemmed metal-backed (MB) or non-stemmed all-polyethylene (AP) tibial component. The articulating geometry of the implants was identical, as was the operative technique and the postoperative regime. The study showed no complications of fixation using AP tibial components, and the migration was the same as that of their metal-backed counterparts. There was no bony collapse or increased subsidence of any part of the tibial component or increased incidence of radiolucent lines in the knees with AP components. Most AP implants were stable between one and two years after surgery, a finding known to be of positive prognostic significance when predicting future aseptic loosening.  (+info)

Radiological features predictive of aseptic loosening in cemented Charnley femoral stems. (6/386)

The radiological features of the cement mantle around total hip replacements (THRs) have been used to assess aseptic loosening. In this case-control study we investigated the risk of failure of THR as predictable by a range of such features using data from patients recruited to the Trent Regional Arthroplasty Study (TRAS). An independent radiological assessment was undertaken on Charnley THRs with aseptic loosening within five years of surgery and on a control group from the TRAS database. Chi-squared tests were used to test the probability of obtaining the observed data by chance, and odds ratios were calculated to estimate the strength of association for different features. Several features were associated with a clinically important increase (>twofold) in the risk of loosening, which was statistically significant for four features (p < 0.01). Inadequate cementation (Barrack C and D grades) was the most significant feature, with an estimated odds ratio of 9.5 (95% confidence interval 3.2 to 28.4, p < 0.0001) for failure.  (+info)

Changes in proximal femoral strain after insertion of uncemented standard and customised femoral stems. An experimental study in human femora. (7/386)

We have compared the changes in the pattern of the principal strains in the proximal femur after insertion of eight uncemented anatomical stems and eight customised stems in human cadaver femora. During testing we aimed to reproduce the physiological loads on the proximal femur and to simulate single-leg stance and stair-climbing. The strains in the intact femora were measured and there were no significant differences in principal tensile and compressive strains in the left and right femora of each pair. The two types of femoral stem were then inserted randomly into the left or right femora and the cortical strains were again measured. Both induced significant stress shielding in the proximal part of the metaphysis, but the deviation from the physiological strains was most pronounced after insertion of the anatomical stems. The principal compressive strain at the calcar was reduced by 90% for the anatomical stems and 67% for the customised stems. Medially, at the level of the lesser trochanter, the corresponding figures were 59% and 21%. The anatomical stems induced more stress concentration on the anterior aspect of the femur than did the customised stems. They also increased the hoop strains in the proximomedial femur. Our study shows a consistently more physiological pattern of strain in the proximal femur after insertion of customised stems compared with standard, anatomical stems.  (+info)

Esthetic option for the implant-supported single-tooth restoration -- treatment sequence with a ceramic abutment. (8/386)

A single implant-supported restoration is one treatment alternative to consider for the replacement of a missing tooth. Technological advances in materials and machining have led to the development of a densely sintered aluminum oxide ceramic abutment, designed and machined using CAD/CAM technology. This manufacturing method improves management of the subgingival depth of the crown/abutment interface and enhances the esthetic qualities of the restoration. However, since this ceramic abutment has less mechanical resistance than metal abutments, its use should be confined to the restoration of incisors and premolars not subjected to excessive occlusal forces.  (+info)

For a correct placement and early fixation of an uncemented hip prosthesis, a centralizer is used. Normally, the centralizer is made of PMMA, the same material as bone cement. When a revision is needed, PMMA is difficult to remove, which is one of the reason not to use a cemented hip prosthesis. With a PMMA centralizer, still PMMA will remain in the bone and needs to be removed in case of a revision. PEGT/PBT is a reabsorbable material, which gives stability during the first month after the placement of the hip prosthesis. However, PEGT/PBT is reabsorped afterwards and, therefore, will not interfere with a revision procedure.. The goal of this study is to analyse if the PEGT/PBT is as safe as PMMA in terms of alignment, direct postoperative complications and clinical results.. Therefore, 100 patients indicated for a cementless Bihapro hip prosthesis which have signed an informed consent are included and randomised over the used centralizers using a weighted randomisation method. All patients ...
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

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 ...
Implants and methods are presented for surgically repairing a hip joint with a proximal femoral prosthesis that comprises femoral head component and a femoral stem component. The femoral stem component comprising a neck portion, a flange portion, a transitional body region and an elongated stem. The femur is prepared for implantation of the femoral hip prosthesis by resecting the proximal femur and reaming a symmetric intramedullary cavity in the femur. The femoral hip prosthesis is then inserted the on the resected femur and in the intramedullary cavity. The femoral hip prosthesis elastically deforms when loaded during use to apply dynamic compressive loads and displacement to the calcar region of the resected proximal femur.
Implants and methods are presented for surgically repairing a hip joint with a proximal femoral prosthesis that comprises femoral head component and a femoral stem component. The femoral stem component comprising a neck portion, a flange portion, a transitional body region and an elongated stem. The femur is prepared for implantation of the femoral hip prosthesis by resecting the proximal femur and reaming a symmetric intramedullary cavity in the femur. The femoral hip prosthesis is then inserted the on the resected femur and in the intramedullary cavity. The femoral hip prosthesis elastically deforms when loaded during use to apply dynamic compressive loads and displacement to the calcar region of the resected proximal femur.
Purpose: Total hip arthroplasty (THA) is a widespread option for treating hip osteoarthritis. Peri-prosthetic complications after THA represent a common event influencing patient outcome and costs. The purpose of this paper is to report the use of ultrasonography (US) to detect peri-prosthetic complications in symptomatic patients who underwent THA. Methods: We retrospectively reviewed the records of patients with THA who underwent imaging evaluation between January 2009 and December 2012 at two different institutions. We evaluated the presence/absence of superficial and/or deep peri-prosthetic collections as well as the presence/absence of a cutaneous sinus tract. For patients who underwent both MRI and US, a concordance correlation analysis between US and MR findings was performed. Results: In the reference period, 532 symptomatic patients (mean age ± standard deviation 74 ± 12 years) underwent X-ray and MRI examinations for suspected peri-prosthetic complications. Among them, 111 (20.9 %) ...

Adult male orangutans exhibit two modes of physical development, flanged and unflanged. Flanged adult males have a variety of secondary sexual characteristics, including cheek pads (called "flanges"), throat pouch, and long fur, that are absent from both adult females and from unflanged males. Flanged males establish and protect territories that do not overlap with other flanged males territories. Adult females, juveniles, and unflanged males do not have established territories. A flanged males mating strategy involves establishing and protecting a territory, advertising his presence, and waiting for receptive females to find him. Unflanged males are also able to reproduce; their mating strategy involving finding females in estrus and forcing copulation. Males appear to remain in the unflanged state until they are able to establish and defend a territory, at which point they can make the transition from unflanged to flanged within a few months. The two reproductive strategies, referred to as ...
Once the restoration has been milled, the clinician must decide which technique best aesthetically enhances the restoration, based on the expectations of the patient and the position of the tooth in the mouth. For molars, polishing with wheels and brushes using a diamond polishing paste are sufficient. For cases where the aesthetic desires of the patient are higher, or the restorations more visible, the clinician can choose to stain and glaze the restoration.. Typically in laboratories, a two-step glaze cycle is used where the appropriate colored stains are placed on the restoration and the restoration is run through the firing cycle. Because the ceramic reconstructions procedure aims to complete the clinical visit in a minimal amount of time, the stain and glaze cycles are conducted in a single step. The glaze is applied first, and then the appropriate stains are placed. The restoration is fired in a single step, which not only fixes the stains, but also fuses the glaze to the surface of the ...

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 ...

Different types of crowns and locations require different preparation, bonding and cementation techniques. This is why Dr. Koeppel has a vast array of cementation and bonding agents, to fit each case specifically.. Loose Crowns - Sometimes crowns become loose or fall off due to the bonding process, materials used, or fit or using expired materials. Matching the proper cement to the bonding agent is critical, and keeping the area clean from saliva, blood, and water during the bonding process is imperative, it is technique sensitive. Over-preparation or under-preparation may also be the culprit. If this is the problem, then re-cementing the crown will not fix the problem. Crowns that have been on for long periods of time can become loose due to decay growing underneath the crown. A little decay is mistakenly left under the crown during preparation or an ill-fitting crown can leak, where bacteria can work itself in. Some of the older cements wash, causing a space between the crown and tooth where ...
The above statement assumes wrongly, that mere age causes rocks to become hard. Sediments are not dried bananas! When sand is first deposited, it has porosities of between 25 to 50%, silts and clays (muds) have between 35 and 70% porosity (This is very old knowledge, see Freeze and Cherry, 1979 and compare with similar values in Hedberg, 1926.). There are two processes which turn sediment into hard rock. The first is compaction, which takes place as the sediment is buried deeper and deeper by overlying sediments. This phenomenon presses the water out of the rock and forces the lithologic particles closer and closer. But that alone doesnt turn a sediment into hard rock. Cementation is the process whereby some form of mineral deposition occurs in the pore spaces between the rock grains, cementing them up. Muds simply wont become solid rock(shale) until they have been compressed by overlying sediments and cementation takes place. Those processes take at least 1000 feet of overburden. ...

leads so rapidly to suspicion. During the 19th century - a time when poisoners flourished, largely because forensic chemistry was still in its infancy - a few notable cases occurred. Probably the best known is that of Thomas Neil Cream, who poisoned a series of London prostitutes with strychnine in the 1890s. Before he was hanged, Cream also took credit for the crimes of Jack the Ripper. A widely publicized earlier case was that of William Palmer, who was executed for the strychnine murder of a friend but suspected of also killing four of his children, all of died of convulsions before their first birthdays.. These are isolated incidents, though. Killers of the day far preferred to use arsenic, antimony and other poisons that tended to mimic natural illness in their effects. Arsenic only fell fully out of favor in the early 20th century, after scientists proved repeatedly that it was readily detectable in a corpse..

RYAN, P and GOGA, IE. Uncemented primary total hip arthroplasty in patients aged 55 years or younger: Results at a minimum of 5 years in a consecutive series. SA orthop. j. [online]. 2014, vol.13, n.1, pp.54-60. ISSN 2309-8309.. INTRODUCTION: Surgical management of younger patients requiring primary total hip arthroplasty is challenging due to increased activity levels, physical demands, and the need for longevity of implanted components. There is debate regarding the most suitable component type, and the optimal fixation, should a stemmed component be utilised. MATERIALS AND METHODS: We retrospectively reviewed a sequential group of patients, aged 55 years or younger at the time of surgery, who underwent uncemented primary total hip arthroplasty, and are currently at a minimum of 5 years post operation. Eighty-eight primary uncemented total hip replacements were performed between January 2004 and December 2006. The patient ages ranged from 18 to 55 years with a mean of 43.1 years at time of ...
We performed this investigation to determine the possible migration starting immediately after surgery and the effect of different weightbearing regimens on the migration pattern of an uncemented hip stem (CLS). Stem migration was determined with radiostereometry analysis with baseline when the patients still were anesthetized. Subsequent examinations were done up to 1 year. Twenty-nine patients (mean age, 55 years; range, 26-63 years) were randomized to either unrestricted weightbearing combined with intensive physiotherapy from the first day after surgery or to partial weightbearing and a conservative training regimen for the first 3 months after surgery. At 1 week, subsidence was -0.03 mm in the unrestricted weightbearing group and 0.01 mm in the partial weightbearing group. At 1 year, subsidence was 1.01 mm in the unrestricted weightbearing group and 0.51 mm in the partial weightbearing group. One patient in the unrestricted weightbearing group had revision surgery because of aseptic ...

Professor Jose Valderas, one of the lead researchers from the University of Exeter Medical School, said: "When youre trying to diagnose cancer, other illnesses can be a distraction either because they also require attention or because they can mask what would otherwise be flagged as a possible sign of cancer.. "Its vital that doctors realise that existing illnesses make a diagnosis of cancer more difficult and stay alert to recognize signs and symptoms of cancer as such. Its also important that patients flag symptoms with their doctor as early as possible, whether its unexplained weight loss or changes to your bowel habits.".

Proposed here is a universally applicable, texturally based classification of clastic sediment that is independent from composition, cementation, and geologic environment, is closely allied to process sedimentology, and applies to all compartments in the source-to-sink system. The classification is contingent on defining the term clastic so that it is independent from composition or origin and includes any particles or grains that are subject to erosion, transportation, and deposition. Modifications to Folks (1980) texturally based classification that include applying new assumptions and defining a broader array of textural fields are proposed to accommodate this. The revised ternary diagrams include additional textural fields that better define poorly sorted and coarse-grained deposits, so that all end members (gravel, sand, and mud size fractions) are included in textural codes. Revised textural fields, or classes, are based on a strict adherence to volumetric estimates of percentages of gravel,

INTRODUCTION: Foot drop is a potentially debilitating complication following injury to the sciatic nerve during primary total hip arthroplasty (THA). The aim of this study was to determine the incidence, risk factors and outcome of this complication within one large surgical practice.. METHODS: We analysed the records of 10,624 primary THAs carried out between January 1993 and November 2017 using a posterior approach. All were under the care of the senior author.. RESULTS: Overall, there were 47 cases (0.44%) of foot drop, but over time the incidence dropped from 0.6% to 0.3% ( p = 0.033). Preoperative protrusio acetabulae ( p , 0.001), female sex ( p , 0.001) and junior grade of surgeon ( p , 0.009) were all significant risk factors. In this series, dysplasia was not a risk factor. 1 year postoperatively, 25 (53.2%) had complete recovery, 12 (25.5%) had ongoing sensory deficit but normal power, and 10 (21.3%) had a residual sensory-motor deficit.. CONCLUSION: Take home message:- In this series, ...
Methods Between 1993 and 1998, 57 primary cementless total hip arthroplasties (THAs) were performed with Mallory-Head titanium femoral component in 50 patients of osteoarthritis. The average age at the time of operation was 58 years old. The mean duration of follow-up was 5.2 years. Anteroposterior radiographs of the hip were made at 6 weeks, 3 months, 6 months, 1 year and every year after the operation. We evaluated the frequency and time of new bone remodelling around the stem. Canal shape was converted to numerical value by using calcar to canal isthmus ratio (CC ratio) of Dorr. The large CC ratio indicates a cylindrical shape and the small value reveals funnel shape of proximal femur. Also intamedullary canal fill was measured. Radiographic signs of stem instability were defined as progressive subsidence and radiolucent or radiodense line around the porous coating surface. ...
The outcome of primary cemented total hip arthroplasty in young patients under 50-years implanted at our Department shows promising long-term prosthesis survival rates. However, many young patients have already an acetabular bone stock deficiency at surgery and they are the more demanding hips. In case of acetabular deficiency, these defects are reconstructed with impacted bone-grafts. Total hip arthroplasty with impacted bone grafts showed a tendency to even better long-term survival rates than hip arthroplasty without acetabular bone reconstruction, which is remarkable. Insight into the level of activity is necessary to determine if these good results are related to lower activity levels in the acetabular reconstruction group or related to the acetabular bone-grafting technique ...
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 ...
The orthopedic market offers more than 200 hundred different femoral stems, some with scientific published results. The influence of stem geometry relatively to stress distribution on the cement mantle has been addressed by some authors. Stem geometry influences the fatigue mechanism process at the stem-cement interface and may cause aseptic loosening. This study presents a new cemented hip femoral concept. The study was based on finite element analysis and in vitro hip replacements. The numerical models allowed us to determine the cement mantle stresses of commercial stems that were compared with the ones of the new concept. The stem developed presents innovative collar and tip geometries and "organic" stem sections. The new cemented hip prosthesis reduces the average cement stresses around 25% relatively to the best commercial stems studied. ...
Periprosthetic fractures occur more frequently around the femoral component than around the acetabular component. Intraoperative femoral fractures can occur during stem placement and are more often associated with uncemented components than with cemented components (in 5.0% vs. 0.3% of cases), due to the high adjustment tension required with uncemented stems(4). They usually occur in the peritrochanteric region, and it is necessary to know their precise location, as well as their relationship with the tip of the metal stem, both of which determine how their treatment will be managed(5). Intraoperative femoral fractures tend to be more common during revisions of hip arthroplasty (7.8%) than during primary arthroplasty (1%), which can be explained by the progression of osteoporosis(4). Postoperative femoral fracture can occur at any time after surgery and is mainly related to traumatic events, typically occurring at the end of the femoral stem, due to "stress risers" that occur at that level, ...
This two-year randomized clinical trial was performed to examine whether the geometry of the cemented femoral prosthesis affects the pattern of strain-adaptive bone remodeling in the proximal aspect of the femur after primary total hip arthroplasty.

The advantage of the onlay is that less sound tooth structure is trimmed away. (As compared when a crown is placed, a greater portion of your original tooth still exists.). Thats an advantage (the usual goal of dentistry is to preserve natural tooth structure to the greatest extent possible), the trade-off however is that retention (keeping the restoration in place) may be a problem. (Fully covering over a tooth [like a crown does] usually aids restoration retention.). In your case, an eMax restoration can be cemented adhesively (bonded) or conventionally (like your PFM probably would be). Either way theres no real reason to expect that retention will be a problem. Its just that as compared to a crown there is more potential for it. The possibility of adhesive cementation makes the point of retention less of an issue for the onlay.. There could be strength concerns (fracture) with an all ceramic onlay (with a gold onlay there wouldnt be). Once again, there doesnt have to be, but as compared ...

TY - JOUR. T1 - Increased Risk of Periprosthetic Femur Fractures Associated With a Unique Cementless Stem Design. AU - Watts, Chad D.. AU - Abdel, Matthew. AU - Lewallen, David G.. AU - Berry, Daniel J.. AU - Hanssen, Arlen D.. PY - 2015/6/1. Y1 - 2015/6/1. N2 - Background: Postoperative periprosthetic femur fractures are an increasing concern after primary total hip arthroplasty (THA). Identifying and understanding predisposing factors are important to mitigating future risk. Femoral stem design may be one such factor.Questions/purposes: The goals of our study were to compare the (1) frequency of periprosthetic femur fracture and implant survivorship; (2) time to fracture in those patients who experienced periprosthetic femur fracture; and (3) predictive risk factors for periprosthetic femur fracture between a unique stem design with an exaggerated proximal taper angle and other contemporary cementless, proximally fixed, tapered stems.Level of Evidence: Level III, therapeutic study.Methods: We ...
Although total hip arthroplasties (THAs) have been extremely successful, survivorship of THAs in young patients with osteonecrosis of femoral head has been limited by aseptic loosening and osteolysis secondary to wear and particulate polyethylene debris [ 1 - 4 ]. Highly cross-linked polyethylene (HXLPE) has been introduced to decrease osteolysis secondary to polyethylene wear debris generation, thereby increasing long-term survivorship of the THAs [ 5 - 7 ]. There are a variety of types of HXLPE sold worldwide today. © Springer-Verlag Berlin Heidelberg 2014 ...
BACKGROUND: Trochanteric osteotomies (TO) facilitate exposure and "true hip reconstruction" in complex primary and revision total hip arthroplasty (THA). However, non-union represents a clinically relevant complication. The purpose of the present study was to identify risk factors for trochanteric non-union. METHODS: All cases of THA approached by TO during the past 10 years were analyzed with respect to potential risk factors for non-union. RESULTS: In 298 cases complete data were available for analysis. Trochanteric union occurred in 80.5%, fibrous union in 5.4% and non-union 14.1%. Risk factor analysis revealed a four times higher risk for non-union in anterior trochanteric slide osteotomies compared to extended trochanteric osteotomies and a three times higher risk in cemented versus non-cemented stems. Multiple logistic regression analysis revealed patients age and use of cement to be independent risk factors for non-union. CONCLUSIONS: Femoral cementation and increasing age negatively ...

News Room - ROE Dental Laboratory: Zirconia Cementation UpdateNews Room - ROE Dental Laboratory: Zirconia Cementation Update

The generally accepted practice of conventionally cementing monolithic ceramic restorations is clinically efficient and is the most popular method of placing our all-zirconia TLZ, BruxZir, and lithium-disilicate eMax restorations. In a recent edition of Inside Dental Technology, however, Dr. Ed McLaren takes issue: "The problem is that these cements are much more soluble than resin-based cements. If, over time, the cement solubilizes and fails, exposing the glass cement to saliva, the restoration can undergo hydrolytic degradation which weakens the material." He recommends bonding these restorations, particularly in situations where the preparation is non-retentive. Dr. Russell Giordano, Boston University Goldman School of Dental Medicine, an authority on dental materials agrees. It has been established that bonding almost doubles the load and increases resistance to failure. Low pressure, sandblasting the interior of the restoration at the laboratory with alumina, and the use of primers, such ...
