Long-term results of spherical acetabular osteotomy. (1/945)

We have examined the effect of the Wagner spherical acetabular osteotomy on preserving the joint in 38 hips with a mean follow-up of 17 years. At the time of the initial operation, 55% of patients had clinical symptoms and 30 joints showed minimal or absent radiological signs of osteoarthritis. At follow-up, 54% of patients had a good functional result. The osteotomy improved the mean centre-edge angle from -3 degrees to +15 degrees, the mean anterior centre-edge angle to 23 degrees and the acetabular head index to 75%. The obliquity of the acetabular roof decreased from 28 degrees to 16 degrees. One patient improved, but 14 deteriorated with joint degeneration. Of these, one progressed because of postoperative deep-tissue infection and five due to undercorrection. One patient needed total joint replacement after 14 years. At 17 years after operation, Wagner osteotomy had prevented progression of secondary arthritis in 63% of cases.  (+info)

Non-operative management of acetabular fractures. The use of dynamic stress views. (2/945)

To assess the stability of the hip after acetabular fracture, dynamic fluoroscopic stress views were taken of 41 acetabular fractures that met the criteria for non-operative management. These included roof arcs of 45 degrees, a subchondral CT arc of 10 mm, displacement of less than 50% of the posterior wall, and congruence on the AP and Judet views of the hip. There were three unstable hips which were treated by open reduction and internal fixation. The remaining 38 fractures were treated non-operatively with early mobilisation and delayed weight-bearing. At a mean follow-up of 2.7 years, the results were good or excellent in 91% of the cases. Three fair results were ascribed to the patients' other injuries. Dynamic stress views can identify subtle instability in patients who would normally be considered for non-operative treatment.  (+info)

Open reduction and internal fixation of acetabular fractures. (3/945)

Between 1982 and 1995, 84 patients with displaced acetabular fractures underwent open reduction and internal fixation in our institution. The mean follow-up was 5.5 years with a minimum of 2 years. There were 33 simple and 51 complex fractures according to the classification of Judet and Letournels. Reduction after operation was anatomical in 49% of the patients, satisfactory in 24%, and unsatisfactory in 27%. Using Merle d'Aubigne's scale, the clinical results were excellent in 39% of the patients, good in 29%, fair in 8%, and poor in 24%. Factors of statistical significance associated with a poor clinical outcome were T-shaped fractures, unsatisfactory reduction (> 3 mm residual displacement), age > 40 years and development of avascular necrosis. Acetabular surgery is demanding, and a high rate of complications can be expected. Trauma centres should designate a group of surgeons who will consistently treat these fractures in order to obtain more experience and better results.  (+info)

The influence of weight-bearing on the measurement of polyethylene wear in THA. (4/945)

We have studied the influence of weight-bearing on the measurement of wear of the polyethylene acetabular component in total hip arthroplasty using two techniques. The measured vertical wear was significantly greater when radiographs were taken weight-bearing rather than with the patient supine (p = 0.001, method 1; p = 0.007, method 2). Calculations of rates of linear wear of the acetabular component were significantly underestimated (p < 0.05) when radiographs were taken supine. There are two reasons for this. First, a change in pelvic orientation when bearing weight ensures that the thinnest polyethylene is brought into relief, and secondly, the head of the femoral component assumes the position of maximal displacement along its wear path. Interpretation of previous studies on both linear and volumetric polyethylene wear in total hip arthroplasty should be reassessed in the light of these findings.  (+info)

Accuracy of EBRA-FCA in the measurement of migration of femoral components of total hip replacement. Einzel-Bild-Rontgen-Analyse-femoral component analysis. (5/945)

Several methods of measuring the migration of the femoral component after total hip replacement have been described, but they use different reference lines, and have differing accuracies, some unproven. Statistical comparison of different studies is rarely possible. We report a study of the EBRA-FCA method (femoral component analysis using Einzel-Bild-Rontgen-Analyse) to determine its accuracy using three independent assessments, including a direct comparison with the results of roentgen stereophotogrammetric analysis (RSA). The accuracy of EBRA-FCA was better than +/- 1.5 mm (95% percentile) with a Cronbach's coefficient alpha for interobserver reliability of 0.84; a very good result. The method had a specificity of 100% and a sensitivity of 78% compared with RSA for the detection of migration of over 1 mm. This is accurate enough to assess the stability of a prosthesis within a relatively limited period. The best reference line for downward migration is between the greater trochanter and the shoulder of the stem, as confirmed by two experimental analyses and a computer-assisted design.  (+info)

The prediction of failure of the stem in THR by measurement of early migration using EBRA-FCA. Einzel-Bild-Roentgen-Analyse-femoral component analysis. (6/945)

We report the ten-year results for three designs of stem in 240 total hip replacements, for which subsidence had been measured on plain radiographs at regular intervals. Accurate migration patterns could be determined by the method of Einzel-Bild-Roentgen-Analyse-femoral component analysis (EBRA-FCA) for 158 hips (66%). Of these, 108 stems (68%) remained stable throughout, and five (3%) started to migrate after a median of 54 months. Initial migration of at least 1 mm was seen in 45 stems (29%) during the first two years, but these then became stable. We revised 17 stems for aseptic loosening, and 12 for other reasons. Revision for aseptic loosening could be predicted by EBRA-FCA with a sensitivity of 69%, a specificity of 80%, and an accuracy of 79% by the use of a threshold of subsidence of 1.5 mm during the first two years. Similar observations over a five-year period allowed the long-term outcome to be predicted with an accuracy of 91%. We discuss the importance of four different patterns of subsidence and confirm that the early measurement of migration by a reasonably accurate method can help to predict long-term outcome. Such methods should be used to evaluate new and modified designs of prosthesis.  (+info)

Retroversion of the acetabulum. A cause of hip pain. (7/945)

We describe a little-known variety of hip dysplasia, termed 'acetabular retroversion', in which the alignment of the mouth of the acetabulum does not face the normal anterolateral direction, but inclines more posterolaterally. The condition may be part of a complex dysplasia or a single entity. Other than its retroversion, the acetabulum is sited normally on the side wall of the pelvis, and its articular surface is of normal extent and configuration. The retroverted orientation may give rise to problems of impingement between the femoral neck and anterior acetabular edge. We define the clinical and radiological parameters and discuss pathological changes which may occur in the untreated condition. A technique of management is proposed.  (+info)

Improving the detection of acetabular osteolysis using oblique radiographs. (8/945)

Visualisation of periacetabular osteolysis by standard anteroposterior (AP) radiographs underestimates the extent of bone loss around a metal-backed acetabular component. We have assessed the effectiveness of standard radiological views in depicting periacetabular osteolysis, and recommend additional projections which make these lesions more visible. This was accomplished using a computerised simulation of radiological views and a radiological analysis of simulated defects placed at regular intervals around the perimeter of a cadaver acetabulum. The AP view alone showed only 38% of the defects over all of the surface of the cup and failed to depict a 3 mm lesion over 83% of the cup. When combined with the AP view, additional 45 degree obturator-oblique and iliac-oblique projections increased the depiction, showing 81% of the defects. The addition of the 60 degree obturator-oblique view further improved the visualisation of posterior defects, increasing the rate of detection to 94%. Based on this analysis, we recommend using at least three radiographic views when assessing the presence and extent of acetabular osteolysis.  (+info)

Background: Porous-coated cups have been widely used in acetabular reconstruction after failed treatment of acetabular fractures, and good results have been reported with the use of these cups; however, the durability and functionality of modular trabecular metal (TM) acetabular components in acetabular reconstruction after failed treatment of acetabular fractures remain unclear. This study aimed to examine the radiographic and clinical outcomes associated with the use of modular TM acetabular components for failed treatment of acetabular fractures to assess the durability and functionality of these components in acetabular reconstruction after failed treatment of acetabular fractures. ...
BACKGROUND: Protrusio acetabuli is a rare anatomic pattern of the hip in which the femoral head protrudes into the true pelvis. The increased depth of the hip and the excessive size of the lunate surface typically lead to severe pincer-type femoroacetabular impingement (FAI); however, to our knowledge, there are no published mid- or long-term studies on results of circumferential acetabular rim trimming through a surgical hip dislocation for patients with this condition. QUESTIONS/PURPOSES: (1) What is the 10-year survivorship of the hips treated with circumferential rim trimming through a surgical hip dislocation compared with a control group of hips that underwent surgery for pincer FAI but that did not have protrusio acetabuli? (2) What are the factors that were associated with a decreased likelihood of survivorship in those hips with the following endpoints: total hip arthroplasty, Merle dAubigné score of less than 15, and/or radiographic progression of osteoarthritis (OA)? (3) Does the ...
The stability of acetabulum reconstructions using reinforcement rings and hooks is important for successful replacement surgery. The objective of this study was to biomechanically determine the effects of the hook on stress and the related micromotions of the acetabular reinforcement ring during the immediate postoperative period. Acetabular reinforcement ring models were developed using a nonlinear, three-dimensional, finite element method. Using a pre-prepared template, we constructed without-hook and bone graft models of varying volumes and material properties. The stress on the inferior margin of the acetabulum was higher in the with-hook model than in the without-hook model, especially with increased bone graft volumes, and the stiffness of the bone graft material was decreased. Relative micromotions in the without-hook model were higher than in the with-hook models. The highest relative micromotion was observed in the model with increased bone graft volume and lower stiffness of bone graft
The acetabulum /æsəˈtæbjʊləm/ (cotyloid cavity) is a concave surface of a pelvis. The head of the femur meets with the pelvis at the acetabulum, forming the hip joint. There are three bones of the os coxae (hip bone) that come together to form the acetabulum. Contributing a little more than two-fifths of the structure is the ischium, which provides lower and side boundaries to the acetabulum. The ilium forms the upper boundary, providing a little less than two-fifths of the structure of the acetabulum. The rest is formed by the pubis, near the midline. It is bounded by a prominent uneven rim, which is thick and strong above, and serves for the attachment of the acetabular labrum, which reduces its opening, and deepens the surface for formation of the hip joint. At the lower part of the acetabulum is the acetabular notch, which is continuous with a circular depression, the acetabular fossa, at the bottom of the cavity of the acetabulum. The rest of the acetabulum is formed by a curved, ...

There has been only one prospective study documenting the outcomes of patients treated with physical therapy for intra-articular conditions of the hip. These conditions included mild FAI and mild developmental dysplasia of the hip. Here, physical therapy was given as a first line treatment. Those who did not make satisfactory improvements in pain or wished to have surgery were then scheduled for surgery to repair the defects. Patients saw improvement in validated outcome measures at one year. Although there have been studies looking at age secondarily in patients with labral tears, there is no prospective evidence to endorse or refute a recommendation of hip arthroscopy for patients of any age being treated for a tear of the acetabular labrum. Most recently, the authors involved in this study performed a retrospective investigation (unpublished data) to capture patients with clinically and radiographically confirmed acetabular labral pathology electing to undergo conservative management defined ...
Hip dysplasia is a common cause of hip pain and functional disability in the 20-40 year old adult. It is characterized by a steep shallow acetabulum resulting in an insufficient coverage of the femoral head. The acetabulum can be retroverted. The proximal femur may be anteverted and the proximal femoral head-neck junction can have formation of exostoses as well. The abnormal biomechanics in the hip joint results in overload of the acetabular rim, which can leads to labral damage with cartilage delamination to follow. The proximal bony abnormality of the femur may result in femoroacetabular impingement aggravating the stress to the rim; worsen the labral stress and the cartilage damage. The natural history of symptomatic hip dysplasia is well described in the literature leading to osteoarthritis without treatment. The periacetabular osteotomy (PAO) is a well established joint preserving surgical treatment. The procedure is known to relieve pain, increase hip joint functionality and to prevent or ...

An alignment system for aligning an acetabular cup insertion instrument utilizes pre-operative preferably standing x-rays and intra-operative x-rays to allow the surgeon to compensate for the position of a patient on an operating room table. The system uses a programmable computer connected to a digital x-ray system and an navigation tracking system to provide input for calculating the inclination and anteversion angles of an acetabular cup impactor based on a pre-operative plan developed from the standing x-rays. The system calculates changes in lengths and angles between anatomic landmarks on the pelvis to alter the intra-operative orientation of the acetabular reaming and impacting instruments to produce the desired inclination and anteversion angles when the pelvis is reoriented as the patient is placed on an operating table.

Background and purpose: Considerable migration of the acetabular cup is required for diagnosis of loosening by conventional radiography. We have developed a new clinically applicable method for assessment of cup loosening using computed tomography (CT). Patients and methods 10 patients scheduled for revision hip replacement due to suspected wear or loosening were scanned twice with CT under torsion loading of the prosthesis. Two independent examiners assessed each patient with respect to motion of the acetabular cup relative to the pelvis using CT volume registration. The CT measurements were compared to findings at revision surgery. Results The method was applicable in 8 of the 10 patients. 1 patient had a severe tremor. In 1 patient, surgery revealed that the hip was ankylotic due to massive ectopic bone formation. This left 8 patients that could be evaluated. 4 cups were loose at surgery, and 3 of these cups could be seen to be mobile by CT. 4 cups that were stable on revision were accurately ...

Background: The hip essentially represents the major weight-bearing joint of the human organism. It is conspicuously characterized by its mobility and complex origination, specific organization and development. The anatomic structures referred to as acetabulum and femoral head arise from the same primitive mesenchymal cells and, by the end of the 11th week of gestation, the hip joint becomes fully formed and continues to develop throughout intrauterine life. During embryonic life, the femoral head grows at a faster rate than the acetabulum, and at the end of gestation the femoral head is approximately less than 50% covered, and after birth, the growth rate of the acetabular cartilage surpasses that of femoral head thus resulting in progressively increased coverage. Methods: Cartilaginous at birth, the ossification of acetabulum is set at around a three-month age period, while ossification centers of the proximal femur start to appear at 4 to 7
An acetabular cup comprising a shell having inner and outer ends, a cavity having an outer opening at the outer end, a surface defining an inner opening at the inner end and external screw threads for threading the shell into the acetabulum and an insert having an external polar cap and a concave bearing surface of generally part spherical configuration opening at a mouth. The insert is adapted to receive a femoral head and has an overhang to reduce the likelihood of dislocation. The insert is receivable in the shell with the polar cap being received in the inner opening of the shell. Interlocking teeth on the surface of the shell and on the polar cap of the insert hold the insert in any of a plurality of different angular positions relative to the shell so that the desired angular orientation of the overhang can be obtained.

This report uses case study methodology to examine the issue of long-term care of the elderly in the United Kingdom, including where that care should take place. The report will examine the difficulties inherent in maintaining independent living for the elderly (in particular the danger and cost of falls). The case study presented is that of an elderly female patient who had suffered from chronic rheumatoid arthritis for over 10 years. She was admitted to hospital several times from December 2003 to January 2004. The discussion of her case is set in the context of the sociology of ageing; long-term care of the elderly and the UK National Service Frameworks, of which standard six relates to falls in the elderly. The report will also consider the problems in deciding whether it is necessary to terminate independent living for an individual. Keywords: Care of the elderly; Holism; Leflunomide; National Service Frameworks; Protrusio acetabuli; Reductionism; Rheumatoid arthritis. ...

Reconstruction of the acetabulum after resection of a periacetabular malignancy is technically challenging and many different techniques have been used with varying success. Our aim was to prepare a systematic review of the literature dealing with these techniques in order to clarify the management, the rate of complications and the outcomes.
INTRODUCTION. The International Elbow Working Group has learned from the world wide experiences in screening for hip dysplasia (HD). Apart of the lack of agreement on radiographic protocols there is also a lack of agreement on interpretation and grading for HD, despite the effort of the Federation Cynologique International (FCI) to make the final scores comparable all over Europe. This is due to the fact that the acceptance of the quality (positioning and exposure) and amount (position with extended femores, sometimes in addition frog leg position) of the films, but also the grading of the amount of laxity (either natural or forced outside the acetabuli), acetabular depth and osteophytes are less well harmonized. In some countries one person judges (per breed or per kennel club), whereas in other countries three screeners grade the radiograph--at the same time or in sequence to come to a final scoring. The different national breeders clubs are organising the HD-screening, influenced by the large ...
2. How is it done?. Doctors replace both balls (femoral head) and socket (acetabulum) during THR surgery. During surgery, once the hip joint is exposed, the head and neck of the femur are removed. The shaft of the femur is then reamed to accept the metal component consisting of the head, neck, and stem. The acetabulum is then reamed to accept a plastic cup. The ball and socket are then replaced into normal position. Both of these implants can be fastened into the bone with or without special cement.. ...
A pelvic implant assembly and associated methods. The implant assembly includes an acetabular component, and a compliant fixator coupling the acetabular component to the pelvis.
A method and apparatus for performing minimally invasive hip surgery for implanting a prosthetic acetabular component into a natural acetabulum.

The retracting section retracts soft tissue in the posterior section of the surgical site and includes a paddle with a curved flare and an elongated curved prong extending outwardly.
A healthy hip joint is one in which the ball-shaped end of the femur bone fits into the acetabulum cavity in the pelvis to form a ball and socket. The acetabulum is large enough and deep enough to enclose the end of the femur completely, allowing for a full and smooth range of motion. Hip […]. ...
