OBJECTIVES To determine the benefits and risks of a non-steroidal anti-inflammatory drug (NSAID) as prophylaxis for ectopic bone formation in patients undergoing total hip replacement (or revision) surgery. DESIGN Double blind randomised placebo controlled clinical trial, stratified by treatment site and surgery (primary or revision). SETTING 20 orthopaedic surgery centres in Australia and ...

OBJECTIVE To determine the prevalence of completed elective total hip replacements in a defined elderly population. DESIGN Cross sectional postal questionnaire survey with additional data and validation from general practice and hospital records. SETTING Six general practices in the English counties of Avon, Somerset, and Oxfordshire. SUBJECTS A total of 7806 patients aged 65 years and ov...

BACKGROUND Total hip replacement for end stage arthritis of the hip is currently the most common elective surgical procedure. In 2007 about 7.5% of UK implants were metal-on-metal joint resurfacing (MoM RS) procedures. Due to poor revision performance and concerns about metal debris, the use of RS had declined by 2012 to about a 1% share of UK hip procedures. This study estimated the lifetime c...

EDUCATIONAL OBJECTIVES As a result of reading this article, physicians should be able to: 1. Identify the available types of reconstruction for failed total hip arthroplasty. 2. Summarize the preoperative workup of patients with failed total hip arthroplasty and massive proximal femoral bone loss. 3. Assess the surgical technique of proximal femoral replacement for failed total hip arthroplasty...

Performance of the controversial metal on metal hip prostheses “continues to create cause for concern,” says the latest annual report from the National Joint Registry of England and Wales. Revision rates—how likely it is that a patient will need an operation to replace a prosthesis—for hip replacements are by far the highest overall for metal on metal (so called because the head and the lining ...

BACKGROUND Hip and knee replacement are some of the most frequently performed surgical procedures in the world. Resurfacing of the hip and unicondylar knee replacement are increasingly being used. There is relatively little evidence on their performance. To study performance of joint replacement in England, we investigated revision rates in the first 3 y after hip or knee replacement according ...

We analysed data from the Oxford hip and knee questionnaires collected by the New Zealand Joint Registry at six months and five years after joint replacement, to determine if there was any relationship between the scores and the risk of early revision. Logistic regression of the six-month scores indicated that for every one-unit decrease in the Oxford score, the risk of revision within two year...

We undertook a randomised prospective follow-up study of changes in peri-prosthetic bone mineral density (BMD) after hip resurfacing and compared them with the results after total hip replacement. A total of 59 patients were allocated to receive a hip resurfacing (n = 29) or an uncemented distally fixed total hip replacement (n = 30). The BMD was prospectively determined in four separate region...

In 1938 Marion Smith-Peterson placed a cobalt chromium cup on a reshaped femoral head to perform the first hip resurfacing.15 Also, in 1938, Philip Wiles performed the first total hip replacement.17 Both procedures revolutionized the treatment of hip arthritis. Most surgeons are opposed to hip resurfacing because it is difficult to perform and there is a high rate of success with total hip repl...
