Levels of metal ions after small- and large-diameter metal-on-metal hip arthroplasty.
Metal-on-metal (MOM) bearings for hip arthroplasty are increasing in popularity. Concern remains, however, regarding the potential toxicological effects of the metal ions which these bearings release. The serum levels of cobalt and chromium in 22 patients who had undergone MOM resurfacing arthroplasty were compared with a matched group of 22 patients who had undergone 28 mm MOM total hip arthro...
متن کاملIntermediate-term trends in serum levels of metal ions after hip resurfacing arthroplasty
BACKGROUND The potential risks associated with hip resurfacing arthroplasty (HRA) are controversial and underestimated. The aim of this study was to explore intermediate-term trends for the levels of cobalt (Co), chromium (Cr), and molybdenum (Mo) ions after HRA. METHODS Forty patients who underwent HRA from October 2005 to December 2010 were recruited to this study. The serum levels of metal...
متن کاملChronic Expanding Hematoma After Metal-on-Metal Total Hip Arthroplasty.
A 76-year-old woman who underwent bilateral metal-on-metal total hip arthroplasty fell 3 years after this procedure and subsequently incurred continuous pain in her buttock. Plain radiographs showed no fracture and no loosening of the hip prosthesis. Magnetic resonance imaging revealed an abnormal, large, thick-walled mass with heterogeneous signal intensity at the right buttock. The prerevisio...
متن کاملGreater Trochanteric Fragmentation After Failed Metal-on-Metal Hip Arthroplasty.
Adverse reaction to metal debris (ARMD) involving the hip joint has emerged as an important reason for failure and revision among patients with metal-on-metal (MOM) hip arthroplasty. To the authors' knowledge, there are no reports of adverse radiographic sequelae in the greater trochanter subsequent to revision for ARMD. The authors describe clinical and radiographic findings in 2 patients who ...
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...
