Stability of the Birmingham hip resurfacing arthroplasty at two years. A radiostereophotogrammetric analysis study.
The Birmingham hip resurfacing metal-on-metal arthroplasty was introduced in 1997 and has shown promising short- to mid-term results. We used radiostereophotogrammetric analysis (RSA) to study the stability of 20 resurfacing arthroplasties over a follow-up period of 24 months. Radiological examinations for RSA were performed immediately after surgery and at two, six, 12 and 24 months after oper...
متن کاملBiomechanics of the Birmingham hip resurfacing arthroplasty.
The effects of the method of fixation and interface conditions on the biomechanics of the femoral component of the Birmingham hip resurfacing arthroplasty were examined using a highly detailed three-dimensional computer model of the hip. Stresses and strains in the proximal femur were compared for the natural femur and for the femur resurfaced with the Birmingham hip resurfacing. A comparison o...
متن کاملAdverse reaction to metal debris after Birmingham hip resurfacing arthroplasty
BACKGROUND AND PURPOSE Concern has emerged about local soft-tissue reactions after hip resurfacing arthroplasty (HRA). The Birmingham Hip Resurfacing (BHR) was the most commonly used HRA device at our institution. We assessed the prevalence and risk factors for adverse reaction to metal debris (ARMD) with this device. PATIENTS AND METHODS From 2003 to 2011, BHR was the most commonly used HRA ...
متن کاملBirmingham hip resurfacing arthroplasty. A minimum follow-up of five years.
We report the survival at five years of 144 consecutive metal-on-metal resurfacings of the hip implanted between August 1997 and May 1998. Failure was defined as revision of either the acetabular or femoral component for any reason during the study period. The survival at the end of five years was 98% overall and 99% for aseptic revisions only. The mean age of the patients at implantation was 5...
متن کاملRoentgen stereophotogrammetric analysis of the Birmingham hip resurfacing arthroplasty. A two-year study.
The Birmingham hip resurfacing (BHR) arthroplasty is a metal-on-metal prosthesis for which no medium- or long-term results have been published. Despite this, it is increasing in popularity as an alternative to stemmed prostheses for younger patients. Since the fixation of the socket is conventional, the major concern is long-term failure of the femoral component. This can be predicted by the us...
