Pigmented villonodular synovitis is a reactive condition characterised by exuberant proliferation of synovial villi and nodules. It may be localised or diffuse and can cause severe articular damage. This report is of 2 patients with pigmented villonodular synovitis of the shoulder causing extensive arthritic changes. Both patients underwent shoulder hemiarthroplasty and total synovectomy and ac...

Haematogenous contamination of cemented total knee replacements with an anaerobic microorganism, Propionibacterium acnes, was studied in rabbits. Seven weeks after operation the bacteria were injected intravenously and seven weeks after this bacterial challenge the experimental bacterial strain was cultured from 50 per cent of the artificial joints. Bacterial growth at the prosthesis was not co...

Fifty patients who had received a hinge arthroplasty of the knee were investigated for possible metal sensitivity. Patients were patch tested against all the metal constituents of the prosthesis. Positive patch tests were found in 32% of patients. Seventeen patients had either lossening or a persistent sterile discharge from the knee. No correlation was found between these complications and met...

Introduction There is no doubt that, since the invention of artificial joint replacement, many thousands of people have enjoyed freedom from disabling pain and immobility. However, this remarkable success story is marred by the incidence of local sepsis following surgery, which can lead to prosthesis loosening and the need for revision surgery. In fact, deep wound infections are the most seriou...

The study involved a 82 years old patient, who was operated 15 years ago for coxarthrosis of the left hip. He underwent placement of total hip prosthesis with good clinical and radiological evolution. Then, 10 years ago, he was operated on the right side, undergoing placement of total hip prosthesis. The evolution on right side was marked by hip pain and a total loss of function of the left low...

BACKGROUND Although modular prosthesis is commercially available to meet requirements in most limb salvage surgeries, customized prosthesis is still needed. In contrast to traditional complicated procedures, rapid prototyping (RP) technique can directly manufacture customized titanium prosthesis. The objectives of this study were to describe the workflow of this technique and show the follow-up...

Introduction Aseptic loosening is the most common cause of total hip arthroplasty (THA) failure and revision surgery. Genetic polymorphisms could be determinant factors for implant loosening. Source of data We performed a comprehensive search of Medline, CINAHL, Googlescholar, Embase and Cochrane databases, using various combinations of the keyword terms 'aseptic loosening', 'gene', 'hip artho...

BACKGROUND The uncemented Nottingham Total Shoulder Replacement prosthesis system (Nottingham TSR) was developed from the previous BioModular shoulder prosthesis taking into consideration the causes of the initial implant's failure. We investigated the impact of changes in the design of Nottingham TSR prosthesis on its survivorship rate. METHODS Survivorship analyses of three types of uncemen...

Early failures have seen titanium fall from favour as a material for cemented femoral stems. Between 1989 and 1994, we performed a prospective review of a consecutive series of 122 cemented total hip replacements using the Ultima straight textured titanium stem, and report the fiveto ten-year clinical and radiological outcomes. There were no revisions for loosening of the femoral stem. Revision...

©2003 British Editorial Society of Bone and Joint Surgery doi.10.1302/0301-620X.85B3.13461 $2.00 etween 1993 and 1996, we undertook 35 Kudo 5 total elbow replacements in a consecutive series of 31 rheumatoid patients. A total of 25 patients (29 procedures) was evaluated at a mean follow-up of six years (5 to 7.5) using the Mayo Clinic performance index. In addition, all patients were assessed f...
