MIIG HV Case Analysis

Total hip arthroplasty revision due to osteolysis is of considerable concern to the orthopedic surgeon because revisions make up 25% of all total hip arthroplasties today. These revision rates coupled with improvements in cup fixation highlight a common, yet challenging problem of osteolytic lesions in the presence of well-fixed acetabular components. Two case reports are presented of osteolytic lesions treated with debridement and a calcium sulfate graft without the removal of a well-fixed cup. At 3 years postoperatively, both cases show excellent results and no evidence of component compromise. (Journal of Surgical Orthopaedic Advances 17(1):58–61, 2008)
