Effect of femoral head size on polyethylene wear and synovitis after total hip arthroplasty - A sonographic and radiographic study of 39 patients
Background and purpose The role of synovitis and high fluid pressure in the loosening process after total hip arthroplasty has gained increasing attention. We investigated the correlation between head size, polyethylene wear, and capsular distention. Patients and methods We analyzed 39 unrevised, radiographically stable hips that had been operated with 28 or 32 mm femoral heads 10 years earlier be
