Dual mobility versus unipolar total hip arthroplasty for neck of femur fractures : a single centre study.

Current national guidelines (NICE) recommends that all medically fit, independently-mobile patients without cognitive impairment receive a total hip arTHAoplasty(THA) for displaced intracapsular neck of femur (NOF) fractures. Dislocation is a concern(2-10%). Dual mobility cups have been suggested to address this complication.

What effect has the major trauma network had on perceptions of trauma care delivery amongst trauma teams in major trauma centres and neighbouring trauma units?

Introduction: The Trauma network was established in April 2012 in England to improve the care of patients with trauma. The care of major trauma was centralised to major trauma centres. This article aims to survey trauma team members (TTM) to compare perceptions of trauma care delivery in major trauma centres (MTC) and trauma units (TU) from where major trauma care has been diverted.

Uncemented metal-on-metal acetabular component: follow-up of 112 hips for a minimum of 5 years.

Background: Aseptic loosening is the major cause of implant failure. In cemented hip arthroplasty, failure of the acetabular side is mainly due to lysis caused by wear particles. By using an implant with low wear characteristics and by enhancing acetabular fixation using an uncemented implant, we aimed to reduce acetabular lysis and thereby loosening.

Early results with the thrust plate prosthesis in young patients with osteoarthritis of the hip.

The purpose of this study was to evaluate the results of the Thrust Plate Prosthesis as a treatment option for osteoarthritis of the hip in young patients. Of the fifty patients (63 hips) reviewed, 31 (62%) were males and 19 (38%) females. Pre-operative diagnosis included primary osteoarthritis (23), developmental dysplasia (8), avascular necrosis (7), Perthes (4), post-traumatic arthritis (3), rheumatoid arthritis (2), ankylosing spondylitis (1), psoriatic arthropathy (1) and slipped upper femoral epiphysis (1).

Changes in metal levels and chromosome aberrations in the peripheral blood of patients after metal-on-metal hip arthroplasty.

A prospective study was performed to investigate changes in metal levels and chromosome aberrations in patients within 2 years of receiving metal-on-metal hip arthroplasties. There was a statistically significant increase of cobalt and chromium concentrations, with a small increase in molybdenum, in whole blood at 6, 12, and 24 months after surgery. There was also a statistically significant increase of both chromosome translocations and aneuploidy in peripheral blood lymphocytes at 6, 12, and 24 months after surgery.
