Brain structure and function in patients after metal-on-metal hip resurfacing.
BACKGROUND AND PURPOSE Hip prostheses that use a metal-on-metal articulation expose the brain to elevated metal concentrations that, in acute excess due to prosthesis malfunction, is associated with neurologic damage, including visual and hearing loss and motor deficits. Here, we examined whether chronic exposure to lower elevated metal levels, typical of well-functioning prostheses, also affec...
متن کاملGroin pain after metal-on-metal hip resurfacing prosthesis
Total hip replacement continues to be a widely successful operation, but persistent groin pain following a metal-on-metal hip resurfacing remains a problem for some patients. The concern regarding the safety and efficacy of metal-on-metal total hip replacements has been rising. We present the case of a 47-year-old man with groin pain after metal-on-metal hip resurfacing. We observed high metal ...
متن کاملThe painful metal-on-metal hip resurfacing.
We carried out metal artefact-reduction MRI, three-dimensional CT measurement of the position of the component and inductively-coupled plasma mass spectrometry analysis of cobalt and chromium levels in whole blood on 26 patients with unexplained pain following metal-on-metal resurfacing arthroplasty. MRI showed periprosthetic lesions around 16 hips, with 14 collections of fluid and two soft-tis...
متن کاملSpinal and Pelvic Motion after Hip Resurfacing Arthroplasty and Metal on Metal Total Hip Arthroplasty
Introduction In normal individuals, hip flexion involves combined motion of the femur with respect to the pelvis and flexion of the lumbar spine. Conflicting reports site insufficient head to neck diameter ratio and fear of instability as limiting factors of post-hip resurfacing (SRA) and total hip replacement (THR), respectively. Restoring anatomical range of motion is important for THR and SR...
متن کاملMetal-on-metal hip resurfacing: a consensus from the Advanced Hip Resurfacing Course, Ghent, June 2009.
We report the consensus of surgical opinions of an international faculty of expert metal-on-metal hip resurfacing surgeons, with a combined experience of over 18,000 cases, covering required experience, indications, surgical technique, rehabilitation and the management of problematic cases.
