Analysis of 118 second-generation metal-on-metal retrieved hip implants. (1/2055)

Osteolysis is due to particulate wear debris and is responsible for the long-term failure of total hip replacements. It has stimulated the development of alternative joint surfaces such as metal-on-metal or ceramic-on-ceramic implants. Since 1988 the second-generation metal-on-metal implant Metasul has been used in over 60 000 hips. Analysis of 118 retrieved specimens of the head or cup showed rates of wear of approximately 25 microm for the whole articulation per year in the first year, decreasing to about 5 microm per year after the third. Metal surfaces have a 'self-polishing' capacity. Scratches are worn out by further joint movement. Volumetric wear was decreased some 60-fold compared with that of metal-on-polyethylene implants, suggesting that second-generation metal-on-metal prostheses may considerably reduce osteolysis.  (+info)

Migration of the Duraloc cup at two years. (2/2055)

We carried out 71 primary total hip arthroplasties using porous-coated, hemispherical press-fit Duraloc '100 Series' cups in 68 consecutive patients; 61 were combined with the cementless Spotorno stem and ten with the cemented Lubinus SP II stem. Under-reaming of 2 mm achieved a press-fit. Of the 71 hips, 69 (97.1%) were followed up after a mean of 2.4 years. Migration analysis was performed by the Ein Bild Rontgen Analyse method, with an accuracy of 1 mm. The mean total migration after 24 months was 1.13 mm. Using the definition of loosening as a total migration of 1 mm, it follows that 30 out of 63 cups (48%) were loose at 24 months.  (+info)

Infections associated with dental procedures in total hip arthroplasty. (3/2055)

Dental procedures may lead to a transient bacteraemia lasting for up to 30 minutes. Of the numerous cases of total hip arthroplasty (THA) reported which have been infected from haematogenous sources, dental procedures have been involved only infrequently. We reviewed the records of 2973 patients after THA. Of the late infections identified in 52 patients, three (6%) were strongly associated with a dental procedure. Infection was diagnosed by culture from the affected joint; Streptococcus viridans was identified in two cases and Peptostreptococcus in one. One patient had diabetes mellitus and another rheumatoid arthritis, both conditions predisposing to infection. The dental operations all lasted for more than 45 minutes and no patient received perioperative antibiotics. Infection of a THA after dental procedures is more common than has been previously suspected. Patients with systemic disease, or who are undergoing extensive procedures, should be considered for prophylactic antibiotic treatment.  (+info)

Subsidence of a non-polished stem in revisions of the hip using impaction allograft. Evaluation with radiostereometry and dual-energy X-ray absorptiometry. (4/2055)

We revised 24 consecutive hips with loosening of the femoral stem using impaction allograft and a cemented stem with an unpolished proximal surface. Repeated radiostereometric examinations for up to two years showed a slow rate of subsidence with a mean of 0.32 mm (-2.0 to +0.31). Fifteen cases followed for a further year showed the same mean subsidence after three years, indicating stabilisation. A tendency to retroversion of the stems was noted between the operation and the last follow-up. Retroversion was also recorded when displacement of the stem was studied in ten of the patients after two years. Repeated determination of bone mineral density showed an initial loss after six months, followed by recovery to the postoperative level at two years. Defects in the cement mantle and malalignment of the stem were often noted on postoperative radiographs, but did not correlate with the degrees of migration or displacement. After one year, increasing frequency of trabecular remodelling or resorption of the graft was observed in the greater trochanter and distal to the tip of the stem. Cortical repair was noted distally and medially (Gruen regions 3, 5 and 6). Migration of the stems was the lowest reported to date, which we attribute to the improved grafting technique and to the hardness of the graft.  (+info)

Determination of Hounsfield value for CT-based design of custom femoral stems. (5/2055)

Ct and advanced computer-aided design techniques offer the means for designing customised femoral stems. Our aim was to determine the Hounsfield (HU) value of the bone at the corticocancellous interface, as part of the criteria for the design algorithm. We obtained transverse CT images from eight human cadaver femora. The proximal femoral canal was rasped until contact with dense cortical bone was achieved. The femora were cut into several sections corresponding to the slice positions of the CT images. After obtaining a computerised image of the anatomical sections using a scanner, the inner cortical contour was outlined and transferred to the corresponding CT image. The pixels beneath this contour represent the CT density of the bone remaining after surgical rasping. Contours were generated automatically at nine HU levels from 300 to 1100 and the mean distance between the transferred contour and each of the HU-generated contours was computed. The contour generated along the 600-HU pixels was closest to the inner cortical contour of the rasped femur and therefore 600 HU seem to be the CT density of the corticocancellous interface in the proximal part of cadaver femora. Generally, femoral bone with a CT density beyond 600 HU is not removable by conventional reamers. Thus, we recommend the 600 HU threshold as one of several criteria for the design of custom femoral implants from CT data.  (+info)

Hydroxyapatite-coated femoral stems. Histology and histomorphometry around five components retrieved at post mortem. (6/2055)

We performed a histological and histomorphometric examination in five cadaver specimens of the femoral and acetabular components and the associated tissue which had been recovered between 3.3 and 6.2 years after primary total hip arthroplasty (THA) using a proximal hydroxyapatite (HA)-coated titanium alloy implant. All had functioned well during the patients' life. All the stems were fixed in the femur and showed osseointegration of both the proximal and distal parts. The amount of residual HA was greatest in the distal metaphyseal sections, indicating that the rate of bone remodelling may be the main factor causing loss of HA. The level of activity of the patient was the only clinical factor which correlated with loss of coating. The percentage of bone-implant osseointegration was almost constant, regardless of the amount of HA residue, periprosthetic bone density or the time of implantation. HA debris was seldom observed and if present did not cause any adverse or inflammatory reaction. Partial debonding did occur in one case as a result of a polyethylene-induced inflammatory reaction.  (+info)

Induction of macrophage C-C chemokine expression by titanium alloy and bone cement particles. (7/2055)

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)

Cytokine levels in synovial fluid from hips with well-functioning or loose prostheses. (8/2055)

We analysed synovial fluid from 88 hips, 38 with osteoarthritis and 12 with well-functioning and 38 with loose hip prostheses. The levels of TNF-alpha, IL-1beta (71 hips) and IL-6 (45 hips) were measured using the ELISA technique. Joints with well-functioning or loose prostheses had significantly increased levels of TNF-alpha compared with those with osteoarthritis. Hips with aseptic loosening also had higher levels of IL-1beta but not of IL-6 compared with those without an implant. The levels of TNF-alpha and IL-1beta did not differ between hips with stable and loose prostheses. Higher levels of TNF-alpha were found in hips with bone resorption of type II and type III (Gustilo-Pasternak) compared with those with type-I loosening. The level of cytokines in joint fluid was not influenced by the time in situ of the implants or the age, gender or area of the osteolysis as measured on conventional radiographs. Our findings support the theory that macrophages in the joint capsule increase the production of TNF-alpha at an early phase probably because of particle load and in the absence of clinical loosening. Since TNF-alpha has an important role in the osteolytic process, the interfaces should be protected from penetration of joint fluid.  (+info)

Short stem prostheses provide conservative surgery and favorable metaphyseal load transmission. However, clinical long‐term results are lacking. Therefore, in vitro trials can be used to predict bone‐implant performance. In this in vitro study, primary stability and stress shielding of a new cementless short stem implant was evaluated in comparison to a straight stem using nine pairs of human cadaver femurs. Primary stability, including reversible micromotion and irreversible migration, was assessed in a hip simulator. Furthermore, changes in the pattern of cortical strain were evaluated. The short stem was more resistant to reversible micromotion and irreversible migration into retroversion. Axial stability was similar, with mean reversible micromotions of 9 µm for the short stem and 7 µm for the straight stem. Proximal load transmission was more physiological with the short stem, though both implants could not avoid stress shielding in Gruen zones 1 and 7. Primary stability of the short ...
In the total hip prosthesis, according to different positions of the patient, there are a variety of loads acting on femoral head which generate stress concentration in the cement called polymethylmethacrylat (PMMA) and consequently in the interfaces stem/cement/bone. This load transfer can provoke loosening of the implant from the femoral bone. This paper focused on optimal stress distribution in the total hip prosthesis and devoted to the development of a redesigned prosthesis type in order to minimize stress concentration in the cement. This study investigated the effect of elastomeric stress barrier incorporated between the stem and femoral head using 3D-finite element analysis. This proposed implant provoked lower load transfer in the cement due to the elastomeric effect as stress absorber. However, the proposed model provided an acceptable solution for load transfer reduction to the cement. This investigation permitted to increase the service life of the total hip prosthesis avoiding the ...
Hip prosthesis surgery process involves an artificial hip that has two parts - a ball and a socket. These parts are known as prosthesis. The artificial hip, like the natural hip, has the ball fitting well into a bowl-shaped socket of the pelvis. When there is a need for a complete hip replacement, the surgeon replaces the ball and the socket both with prosthesis.. Basis for picking right prosthesis. The surgeons pick right type of prosthesis after evaluating a patients condition. Generally, a patients age and lifestyles are considered mainly before picking up suitable prosthesis. However, the surgeons usually prefer using hip prosthesis India products that they are comfortable with. Orthopedic surgeons usually want to use the implants that they have been using for many years.. So, that will also be a basis of selecting hip prosthesis for a patient. But make sure that you talk to your surgeon about the selection of particular brand of hip prosthesis India. Right choice of prosthesis is ...
Short stems have become more and more popular for cementless total hip arthroplasty in the past few years. While conventional, uncemented straight stems for primary total hip arthroplasty (THA) have shown high survival rates in the long term, it is not known whether uncemented short stems represent a reasonable alternative. As cortical hypertrophy has been reported for short stems, the aim of this study was to determine the radiographic prevalence of cortical hypertrophy and to assess the clinical outcome of a frequently used short, curved hip stem. We retrospectively studied the clinical and radiographic results of our first 100 consecutive THAs (97 patients) using the Fitmore® hip stem. Mean age at the time of index arthroplasty was 59 years (range, 19 - 79 years). Clinical outcome and radiographic results were assessed with a minimum follow-up of 2 years, and Kaplan-Meier survivorship analysis was used to estimate survival for different endpoints. After a mean follow-up of 3.3 years (range, 2.0 - 4

Background: Avascular necrosis (also osteonecrosis, bone infarction, aseptic necrosis, ischemic bone necrosis, and AVN) is a disease where there is cellular death (necrosis) of bone components due to interruption of the blood supply. The current well accepted treatment for arthritis secondary to AVN in hip joint is total hip replacement.Methodology: A prospective study was carried out on 30 patients who underwent cemented/uncemented Total Hip Replacement in Department of Orthopaedics, Vydehi Institute of Medical Sciences and Research Centre, Whitefield, Bangalore.Results: This study has shown that, the mean age of patients in the study group was 42.30±11.43 years. About 43.3% of the avascular necrosis patients in the study group belonged to 31-40 years age group. The sex distribution of the study group has shown that, about 76.7% of the patients were Males and 23.3% were females. The analysis of patients for the etiology of AVN showed that 70.0% of the patient developed AVN of hip joint without ...
Hip navigation based on preoperative EOS(TM) imaging could help to improve the accuracy of cup positioning like other computer assisted hip surgery, but it would also simplify the procedure in lateral decubitus. Indeed, the registration of the controlateral antero superior iliac spine and the pubis is not necessary with this technique. The target population of the study is the one affected with primitive hip osteoarthritis for which an indication of prosthesis of total hip has been chosen Expected Result: Simplification of the procedure of navigation of the cup. Decrease in the number of cups positioned out of the security zone compared to the standard manual technique of cup positioning. A result of 50% of good positioning is expected with the manual technique versus 80% with the technique of navigation based on EOS(TM).. MAIN OBJECTIVE: Compare the surgical treatment of total hip prosthesis without assistance by computer and total hip prosthesis with navigation based on imaging EOSTM ...
Background -Total hip arthroplasty went through the many changes in recent years.The trend is towards a cementless shorter stems and a proximal implant anchoring with the preservation of pt. own bone substance. One stem representative of these design is the metha modular short stem prosthesis. This design justifies the expansion of the indication to younger patients,and should fulfill their requirements in terms of quality of life and activity in every day life. At the same time,the opportunity to leave as many bone structure untouched is possible leaving considerable bone for a potential revision case.. Material and Method: To determine the clinical and radiological outcome in 25 patients of total hip replacement with short stem (metha) in the department of orthopaedics at Amandeep hospital, Amritsar, Punjab, all patients were followed for a period of one year, with harris hip score being calculated pre operatively and post operatively at 3month,6month and at time of completion of ...
LEARMONTH, Ian D. The rise and fall of large bore metal-on-metal hip prostheses. SA orthop. j. [online]. 2014, vol.13, n.3, pp.21-27. ISSN 2309-8309.. ABSTRACT Metal-on-metal was the first articular couple to be successfully used in total hip replacement. Large heads and high frictional torque resulted in a high incidence of implant loosening. This led Charnley to introduce the low friction arthroplasty where the torque was reduced by using small heads and low friction hard-on-soft bearings. Osteoarthritis is a disease of cartilage, and resurfacing arthroplasty is therefore intuitively the logical conservative surgical solution. The early resurfacing devices with metal-on-plastic bearings were associated with catastrophic wear of the plastic. In the 1990s resurfacing was revisited, and metal-on-metal was selected to resolve the challenge of the bearing surface. Various factors were not initially recognised as being critical for the successful outcome of these implants. These include the ...

The Nordic registry reports patients under 50 years old with total hip replacements realize only 83% 10-year implant survivorship. These results do not meet the 95% 10-year survivorship guideline posed by the UKs National Institute for Health and Care Excellence (NICE) in 2014. The purpose of this study is threefold: First, we evaluate if metal-on-metal hip resurfacing arthroplasty meets these high standards in younger patients. Next, we compare outcomes between age groups to determine if younger patients are at higher risk for revision or complication. Lastly, we assess how outcomes between sexes changed over time. From January 2001 to August 2013, a single surgeon performed 1285 metal-on-metal hip resurfacings in patients younger than 50 years old. We compared these to an older cohort matched by sex and BMI. Kaplan-Meier implant survivorship was 96.5% at 10 years and 96.3% at 12 years; this did not differ from implant survivorship for older patients. Implant survivorship at 12 years was 98 and 93%

N2 - From 1984 to 1987, a complete, single-layered, porous-coated femoral component (Roy-Camille type) was used for primary cementless total hip replacement in 80 patients. Seventy-two patients (77 hips) with a minimal follow-up of 5 years (mean 7.2 years) were assessed clinically and radiographically. Thigh pain occurred in 4 hips. Osteolysis appeared in 5 hips. Cortical thinning around the femoral component was significant at the proximal and middle levels. In total, 6 femoral components failed, which led to reoperation due to aseptic loosening (4 hips) and septic loosening (2 hips). The hip rating score (modified dAubigne and Postel rating system) in the surviving hips progressed from 9.0 (range 6-10) preoperatively to 16.3 (range 12-18) points at the latest follow-up. From this study, we found that the complete, single-layered, porous-coated ...

When you are going to have anterior hip replacement surgery, you should do your homework. You will want to be aware of possible hip replacement recalls. Because youre getting a prosthesis inserted into your body, you should know if there have been any recalls as well as what type and brand of hip prosthesis that your surgeon plans on using. This may prevent problems down the road. The most well- known recall was the DePuy hip replacement recall.. The reason for the DePuy hip replacement recall included that there were fifty percent failure rate in the hip prosthesis. The DePuy hip prosthesis is made of metal. There is the chance of metals getting into the blood. Because of the DePuy hip replacement recall, if you have this type of hip its important to get a blood test to determine if any metals have gotten into the blood.. As with any procedure, you want to be aware of possible hip replacement complications. While these are very few, you should still know what they are. Some examples of ...

High short-term failure rates have been reported for several metal-on-metal hip resurfacing (MoMHR) designs. Early observations suggested that MoMHRs revised to total hip arthroplasties (THAs) for pseudotumor had more major complications and inferior patient-reported outcomes compared with other revision indications. However, little is known about implant survivorship and patient-reported outcomes at more than 5 years after MoMHR revision.(1) What are the implant survivorship, proportion of complications and abnormal radiological findings, and patient-reported outcomes at a median of 10 years after MoMHR revision surgery? (2) Are survivorship, complications, and patient-reported outcomes influenced by revision indication? (3) Do any other factors predict survivorship, complications, and patient-reported outcomes?Between 1999 and 2008, 53 MoMHR revision procedures in 51 patients (mean age, 55 years; 62% female) were performed at one center and were all included in this retrospective study.

DePuy Orthopaedics, Inc. is facing public scrutiny regarding the reportedly premature loosening and failure of its Pinnacle hip prostheses. Within the past year alone, the FDA has received hundreds of adverse reports regarding failures or other complications related to the Pinnacle device.[1] Patients who experience a premature failure of their hip prostheses typically require surgery to remove the failed hip replacement, placement of a new prostheses, as well as rehabilitation associated with this major surgery.. Many lawsuits involving failed Pinnacle hip implants have already been filed in both state and federal courts across the country. On May 24th, the Judicial Panel on Multidistrict Litigation (JPMDL) established MDL No. 2244 devoted to litigation surrounding the DePuy Pinnacle hip implants.[2] The JPMDL has assigned In Re: DePuy Orthopaedics, Inc. Pinnacle Hip Implant Products Liability Litigation to Judge Kinkeade in the Northern District of Texas. DePuy Orthopaedics, Inc. is a unit ...
It is believed that all-metal hip replacements, which consist of a metal acetabular cup and metal femoral head, can shed minute particles of cobalt and chromium into surrounding tissue, and even into a patients blood stream. This can result in a condition called metallosis, which causes the death of tissue around the implant, including bone and muscle. Metal ions can also cause irreversible damage to DNA in cells, and have been found in many organs following hip replacements, including marrow, blood, liver, kidneys and bladder.. Metal-on-metal hip implants have been the subject of safety concerns since the August 2010 global recall of DePuy Orthopaedics ASR hip implants. In May of last year, the U.S. Food & Drug Administration (FDA) asked 21 makers of metal-on-metal hip implants to conduct safety studies of their devices. In June, the agency will convene a panel of outside advisers to discuss the problems related to metal-on-metal hip replacements. Since then, several studies, including recent ...

This latest hip recall further supports calls that metal-on-metal hip implants pose unsafe risks to patients. In August 2010, DePuy Orthopaedics, a subsidiary of Johnson & Johnson, issued a voluntary worldwide recall of its ASR hip replacement devices after data revealed that the implants had excessively high failure rates. Approximately 93,000 people were affected by that recall. Additionally, since that time, there has been a flood of litigation over the recalled ASR hip replacements and other metal-on-metal hip systems. In the United States and abroad, there is growing concern among medical experts regarding the safety of all-metal artificial hip implant systems. Although the Stryker Rejuvenate and ABG II modular-neck hip stems can be used as a component of either metal or ceramic hip implants, the products have a metal-on-metal modular junction, which can fret and corrode. Similar to the recalled ASR hip implants, the Rejuvenate and ABG II modular-neck stems suffer from defects common in ...
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 ...

Bernstein Liebhard LLP notes the publication of a new study investigating cancer risks in metal-on-metal hip implant patients. The study, which was published in the February 2014 issue of Acta Orthopaedica, compared data from the Finnish Arthroplasty Register involving 10,728 patients with metal-on-metal hip implants and 18,235 patients who received other types of hip replacements. Though the findings suggested that all-metal hips were not associated with a higher risk of cancer overall, the data did indicate that metal-on-metal hip implant patients were more likely to develop soft-tissue sarcoma and basalioma. The all-metal hip patients were followed for an average of 4.6 years, while those with other devices were followed for an average of 6 years ...
The Wright Conserve hip litigation involves lawsuits related to the Wright Conserve Total Hip Implant System, Conserve Total A-Class Advanced Metal Hip Implant System, and the Conserve Resurfacing System. All of these devices are metal-on-metal hip replacements, in which the femoral ball and cup are made from a chromium/cobalt alloy. On January 17th, the U.S. Food & Drug Administration (FDA) issued a Safety Communication warning that metal debris shed by all-metal hips can damage the bone and/or soft tissue surrounding the implant and joint. These metal ions cans also enter the bloodstream and travel to other parts of the body, where they may cause additional symptoms or illnesses, the agency said. The FDA has advised doctors to consider metal ion testing if patients are experiencing symptoms of hip implant failure. The agency also proposed a rule that would make all-metal hips ineligible for 510(k) approvals, which allowed devices like the Wright Conserve hip to come to market without premarket ...

Muscle atrophy is a well-known complication from metal-on-metal hip implants. A recent article discussed changes in soft tissue seen on MRIs over time with patients implanted with metal-on-metal modular stemmed prostheses and hip resurfacings. The median implantation time was 7 years. The authors described the muscle atrophy and pseudotumor formation that develops as part of the inflammatory response to metal wear debris and concluded that both worsen over time. This information could assist doctors with management of their patients with THAs to consider earlier revision surgery to prevent permanent muscle destruction. ...

Sciatic nerve injuries following total hip arthroplasty are disabling complications. Although degrees of injury are variable from neuropraxia to neurotmesis, mechanical irritation of sciatic nerve might be occurred by protruding hardware. This case shows endoscopic decompression for protruded acetabular screw irritating sciatic nerve, the techniques described herein may permit broader arthroscopic/endoscopic applications for management of complications after reconstructive hip surgery. An 80-year-old man complained of severe pain and paresthesias following acetabular component revision surgery. Physical findings included right buttock pain with radiating pain to lower extremity. Radiographs and computed tomography imaging showed that the sharp end of protruded screw invaded greater sciatic foramen anterior to posterior and distal to proximal direction at sciatic notch level. A protruding tip of the acetabular screw at the sciatic notch was decompressed by use of techniques gained from experience
We assessed the orientation of the acetabular component in 1070 primary total hip arthroplasties with hard-on-soft, small diameter bearings, aiming to determine the size and site of the target zone that optimises outcome. Outcome measures included complications, dislocations, revisions and ΔOHS (the difference between the Oxford Hip Scores pre-operatively and five years post-operatively). A wide scatter of orientation was observed (2sd 15°). Placing the component within Lewinneks zone was not associated withimproved outcome. Of the different zone sizes tested (± 5°, ± 10° and ± 15°), only ± 15° was associated with a decreased rate of dislocation. The dislocation rate with acetabular components inside an inclination/anteversion zone of 40°/15° ± 15° was four times lower than those outside. The only zone size associated with statistically significant and clinically important improvement in OHS was ± 5°. The best outcomes (ΔOHS | 26) were achieved with a 45°/25° ± 5° zone. This study

This study compared radiological and clinical results of Mallory-Head (Biomet, Warsaw, Indiana) cementless total hip arthroplasty (THA) by anatomical (AP group) or high cup placement (HP group) for Crowe I to III developmental dysplasia of the hip. Of the 68 hips studied, 43 hips were available for 15.3-year follow-up. Ten cups were placed at anatomical center with bulk bone grafting, and 33 cups were at high hip center without bulk bone grafting. No acetabular or femoral components showed loosening in either group. One standard polyethylene liner in a highly placed cup was revised due to excessive wear after 11 years. The average rate of polyethylene wear was 0.128 mm/year in the AP group and 0.148 mm/year in the HP group (except for the revision case). The extent of grafted bone coverage was 34.6% in the AP group. Hip center height was 24.5 mm from the inter-teardrop line in the HP group. The center of the hip horizontal location in the AP group (24.5 mm) and HP group (26.4 mm) was ...
TY - JOUR. T1 - Anatomic Hip Center Decreases Aseptic Loosening Rates after Total Hip Arthroplasty with Cement in Patients with Crowe Type-II Dysplasia. T2 - A Concise Follow-up Report at a Mean of Thirty-six Years. AU - Watts, Chad D.. AU - Abdel, Matthew. AU - Hanssen, Arlen D.. AU - Pagnano, Mark. PY - 2016/6/1. Y1 - 2016/6/1. N2 - We previously reported the two to twenty-two-year results of 145 total hip arthroplasties (THAs) with cement performed from 1969 to 1980 in 117 patients with Crowe type-II dysplasia. The purpose of the present study was to update the long-term effects of a nonanatomic hip center on component loosening and aseptic revision in this cohort. Forty-nine patients (sixty hips) were alive at a mean of thirty-six years. The overall cumulative incidence of aseptic revision at thirty-five years was 32% for acetabular cups and 21% for femoral stems. Acetabular loosening was less likely with a hip center placed within the true acetabular region (TAR), ,15mmsuperior to the ...

Patients with advanced arthritis or chronic hip joint pain may be candidates for either traditional total hip replacement (total hip arthroplasty) or Birmingham hip resurfacing.. In a traditional total hip replacement, the head of the thighbone (femoral head) and the damaged socket (acetabulum) are both removed and replaced with metal, plastic or ceramic components.. In hip resurfacing, the femoral head is not removed, but is instead trimmed and capped with a smooth metal cover. The damaged bone and cartilage within the socket are removed and replaced with a metal shell, just as in a traditional total hip replacement.. Each of these procedures is a type of hip replacement, but there are important differences between the two. Your orthopedic surgeon will talk with you about the different procedures and help you decide which operation would be best for you.. ...
The procedure involves removing the femoral head (ball) and a portion of the acetabulum (socket) of the hip joint and replacing them with a prosthetic ball and socket, similar to what is done in people. The implants are either held in place with bone cement (cemented system) or without bone cement (cementless system). These days, the cementless system is more commonly used and preferred by most surgeons.. The procedure maintains a high rate of success. Most dogs have a significant improvement in quality of life. Dogs that have had a total hip replacement compensate well by shifting their weight to the operated limb. Because of this, 80% of dogs receiving a total hip replacement do not need to have a total hip replacement performed in the opposite hip, even if it has significant arthritic changes.. The recovery time for total hip replacement is generally 8 to 12 weeks. Restricted activity during this time is important to assure proper healing. Complications of the procedure are rare but can ...
The impact of surgeon handedness on acetabular cup orientation in total hip arthroplasty (THA) is not well studied. The aim of our study is to investigate the difference of cup orientation in bilateral THA performed by right-handed surgeons using posterolateral approach and which cup could be fitter to Lewinnecks safe zone. The study consisted of 498 patients that underwent bilateral THA by three right-handed surgeons in our hospital. Postoperative acetabular cup anteversion and abduction on an anteroposterior pelvic radiograph were measured by Orthoview software (Orthoview LLC, Jacksonville, Florida). Furthermore, the percentage of cup placement within the safe zone was compared. The mean anteversion was 25.28 (25.28° ± 7.16°) in left THA and 22.01 (22.01° ± 6.35°) in right THA (p | 0.001). The mean abduction was 37.50 (37.50° ± 6.76°) in left THA and 38.59 (38.59° ± 6.84°) in right THA (p = 0.011). In the left side, the cup was positioned in Lewinneks safe zone in 52% for anteversion, 87

One type of hip fracture, called a femoral neck fracture, involves a break in the narrow part of the femur bone where the head of the femur is joined to the main shaft. The break can be either undisplaced, which involves very little separation at the fracture site, or displaced, in which there is substantial separation. For displaced fractures, surgeons usually choose between internal fixation and hip arthroplasty, which is also known as hip replacement.. Patients receiving hip arthroplasty may undergo either a total hip arthroplasty or a hemi-arthroplasty. Which surgical method is best for the patient is unknown. Advocates of total hip replacement claim better improvements in patient function and quality of life. On the other hand, advocates of hemi-arthroplasty, which include most orthopaedic surgeons, claim reduced rates of dislocation and deep vein thrombosis, shorter operating times, less blood loss, and a technically less demanding surgical procedure. This study will compare total hip ...

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. ...
Aim. The aim was to evaluate patients perioperative pain experience after total hip replacement and patients satisfaction with pain management.. Background. Total hip arthroplasty is a common surgical procedure intended to reduce pain and return patients to better function. Realistic expectations about total hip arthroplasty is important for optimal postoperative recovery and the information must be adapted to fit the individual patient.. Methods. A descriptive design was used comparing patients outcome data. Pitmans test was used for statistical analyses. Adult patients (n ¼ 112) undergoing surgical hip replacement procedures answered a 17-item questionnaire on the fourth postoperative day. The questionnaire included given alternatives and visual analogue scales (0-100 mm) for the pain assessment.. Result. The patients postoperative pain experience after hip replacement surgery was in average low, 33Æ1 mm on a 100 mm visual analogue scale. Patients pain experience was reported to be ...

Materials and Methods: This prospective observational study was carried out in the Department of Orthopaedics, Institute of Medical Sciences, Banaras Hindu University, Varanasi, Uttar Pardesh, India, from November 2016 to January 2018. Total 120 patients were patients treated with total hip replacement. Radiographic evaluation includes Loosening of the acetabulum and femoral components, Inclination of Acetabular cup, Stem position of femoral component, Vertical subsidence, Migration of the Acetabular cup and Heterotopic Ossification. Modified Harris hip score was used for clinical and functional evaluation of patients. Plain X-ray pelvis with both hips and proximal femur-AP view and X-ray of the operated hip lateral view for radiological evaluation. Results: Out of 120, 86 patients were male and 34 female, most of the patients in were above 50 year and followed by 40-50
Patients with osteoarthritis that is particularly severe and unresponsive to the conservative treatments will usually require total hip replacement surgery, also referred to as total hip arthroplasty. Severely degenerated joints can be treated by fusion (arthrodesis) or replacement with an artificial joint (arthroplasty). After surgery, it is extremely important to begin physical therapy immediately. In fact, it is common for physical therapy to begin the day after surgery.. In this series, we will discuss total hip replacement therapy. Although this is considered one of the most successful surgeries conducted in the world today, immediate physical therapy following surgery is a critical component that cannot be stressed enough.. What is a total hip replacement?. A total hip replacement is a surgical procedure whereby the diseased cartilage and bone of the hip joint is surgically replaced with artificial materials. The hip joint is composed of a ball and socket joint. The socket is a cup-shaped ...
Aseptic loosening from polyethylene debris is the leading cause of failure for metal-on-polyethylene hip implants. The accumulation of wear debris can lead to osteolysis, the degradation of bone surrounding the implant components. In the present study, a parametric three-dimensional finite element model of an uncemented total hip replacement prosthesis was constructed and implanted into a femur model constructed from computed tomography (CT) scan data. Design optimization was performed considering volumetric wear as an objective function using a computational model validated in a previous study through in vitro wear assessment. Constraints were used to maintain the physiological range of motion of wear-optimum designs. Loading conditions for both walking and stair climbing were considered in the analysis. In addition, modification of the acetabular liner surface nodes was performed in discrete intervals to reflect the actual wear and creep damage occurring on the liner surface. Stair climbing ...
OBJECTIVE To analyze the effect of biomechanical reconstruction of the hip in metal-on-metal total hip resurfacing. METHODS Thirty patients undergoing hip resurfacing arthroplasties were enrolled in this study. The clinical outcomes of the patients were assessed according to the Harris Hip Score before and after the surgery, X-ray examinations and biomechanical reconstruction evaluations. RESULTS After the operation, the length of the patients legs was shortened by a mean of 2.4 mm. and the femoral offset was decreased by a mean of 5.45 mm. No dislocation were be found in these patients. The preoperative Harris Hip Score was 36.69-/+7.16, significantly lower than that postoperative score (89.63-/+3.36, P|0.01). CONCLUSION Precise biomechanical reconstruction of the hip can be achieved in hip resurfacing arthroplasty, and the stability and functional restoration is guaranteed by large diameter prosthesis design.

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, ...
