Fretting and corrosion in modular-neck total hip arthroplasty femoral stems.
BACKGROUND During total hip arthroplasty, use of a modular femoral neck on a stemmed implant allows optimization of neck anteversion, length, and offset, resulting in more accurate balance. We performed a retrospective analysis of a consecutive cohort of patients who had undergone total hip arthroplasty with a modular-neck hip system with ceramic-on-ceramic bearings. METHODS We reviewed the r...
متن کاملFretting and Metal Release of Modular Neck Total Hip Arthroplasty
INTRODUCTION: In current total hip arthroplasty, modularity between the head-neck connection of the femoral stem is well established. More recently, implants with an additional modular connection between the neck and stem have become more popular. The ability to adjust the head centre relative to the stem axis intraoperatively, by connecting the neck in different positions, guarantees high vers...
متن کاملOsteotomy for Revision Total Hip Replacement
Discussion. We previously reported bone and fat levels some I 2 times higher than those after systemic injection (Hoddinott et al 1990) and have now extended our sampling to provide a pharmacokinetic profile over the important 24 hours after operation (Fig. 1). The results indicate that the regional intravenous administration of a single 750 mg dose of cefuroxime gave satisfactory haematoma lev...
متن کاملEnhanced Wear and Corrosion in Modular Tapers in Total Hip Replacement - An in-vitro biomechanical study
Introduction The use of large cobalt chrome femoral heads reduces dislocation and increases the range of motion. However, failure of large head metal on metal hip replacements (LHMMHR) has recently been identified and is believed to be associated with the high torque at the interface of standard modular taper junction leading to fretting and corrosion. Compared with standard 28 mm heads the rel...
متن کاملEarly corrosion-related failure of the rejuvenate modular total hip replacement.
BACKGROUND The Rejuvenate modular-neck stem implant (Stryker Orthopaedics, Mahwah, New Jersey) was recently recalled due to corrosion at the femoral neck-stem junction. The purpose of this study was to investigate the rate of corrosion-related failure and survivorship of this implant and analyze the correlation of implant and patient factors with serum metal ion levels and revisions. METHODS ...
