A Prospective Metal Ion Study of Large-Head Metal-on-Metal Bearing: A Matched-Pair Analysis of Hip Resurfacing Versus Total Hip Replacement
The current study measured ion release among large-head metal-on-metal hip bearings. Twenty-six patients with a modular, Profemur® TL with A-Class® big femoral head total hip replacement were matched (gender, femoral…
Revisions of Metal-on-Metal Hip Resurfacing: Lessons Learned and Improved Outcome
This retrospective, consecutive case series of a single surgeon performed between 2001 and 2010 assesses the outcome following revision of metal-on-metal hip resurfacing arthroplasties (N = 113). Mean time to revision…
The Future of Hip Resurfacing
With experience in metal-metal resurfacing, several opportunities to improve resurfacing technology have been identified. There is a need for better education on hip resurfacing in residency training programs. The majority…
Failure Modes of 433 Metal-on-Metal Hip Implants: How, Why, and Wear
Metal-on-metal total hip replacements (THRs) and hip resurfacings are coming under increasing scrutiny in light of concerns that they fail because of high wear and elevated metal ions. The aim…
Incidence and Significance of Femoral Neck Narrowing in the First 500 Conserve® Plus Series of Hip Resurfacing Cases: A Clinical and Histologic Study
Narrowing of the femoral neck after metal-on-metal hip resurfacing arthoplasty has been reported as a common radiologic feature, although its significance is still unknown. This study reports the presence and…
Comparison of Fully Porous-Coated and Hybrid Hip Resurfacing: A Minimum 2-Year Follow-Up Study
The purpose of this study was to compare clinical and radiological outcomes of the first 191 fully porous-coated hip resurfacing arthroplasties with 96 hybrid hip resurfacing arthroplasties performed during the…
Imaging of Metal-On-Metal Hip Resurfacing
Conventional radiography is the primary imaging modality to evaluate the condition of hip resurfacing implants and the preferred method of assessing implant stability over time. Radiographs assess the angle of…
Reducing Metal Ion Release Following Hip Resurfacing Arthroplasty
Recent guidelines have suggested that routine postoperative care of patients with metal-on-metal hip prostheses should involve metal ion analysis. This study sought to investigate the relationship between bearing surface wear…
Complications After Metal-on-Metal Hip Resurfacing Arthroplasty
This article determines the incidence and cause of the complications commonly associated with metal-on-metal hip resurfacing implants and the proposed methods to prevent these complications. The literature available in PubMed…
