Objectives To compare 10 year mortality rates
among patients undergoing metal-on-metal hip resurfacing and total hip
replacement in England.
Setting English hospital episode statistics
database linked to mortality records from the Office for National
Population All adults who underwent primary
elective hip replacement for osteoarthritis from April 1999 to March 2012.
The exposure of interest was prosthesis type: cemented total hip
replacement, uncemented total hip replacement, and metal-on-metal hip
resurfacing. Confounding variables included age, sex, Charlson comorbidity
index, rurality, area deprivation, surgical volume, and year of operation.
Results 7437 patients undergoing metal-on-metal
hip resurfacing were … Read the rest

The purpose of this study was to evaluate the
clinical outcomes and possible causes of early
failure in a multicenter trial of metal-on-metal
hip resurfacing. Two hundred patients were
prospectively enrolled and followed for an
average of 31.2 months (range, 12-54 months). Of
200 patients, 14 (7.0%) required revision
surgery at a mean time of 19.5 months (range,
3-47 months). Patients with failures

Is there added risk in resurfacing a femoral head with cysts?
Thomas P Gross and Fei Liu 17 October 2011
Femoral head cysts have been identified as a risk factor for
early femoral failures after metal-on-metal hip resurfacing
arthroplasty (HRA) based on limited scientific data.
However, we routinely performed HRA if less than 1/3 of the
femoral head appeared destroyed by cysts on the preoperative
radiograph. This study was undertaken to analyze whether
there was an added risk of early femoral failures in HRA
when femoral head cysts were present.
This retrospective case-control study included 939 MOM
Previous data on the survivorship of the Birmingham Hip Resurfacing (BHR) implant have come from design surgeons and large national databases outside of the United States, and there is a lack of reported outcomes of surface replacement arthroplasty from US centers. A retrospective study was undertaken of 1271 hips treated with a BHR system (Smith & Nephew, Memphis, Tennessee) between June 2006 and September 2008 at 6 high-volume total joint centers in the United States. ..
…At 2 to 4 years of follow-up, the revision rate and the major complication rate with the … Read the rest
