Radiographic and histopathologic analysis of osteolysis after total shoulder arthroplasty.
HYPOTHESIS This study analyzed clinical, radiographic, and histologic data from failed total shoulder arthroplasties (TSAs) to determine factors associated with osteolysis. MATERIALS AND METHODS From 1985 to 2005, 52 patients (mean age, 61.6 years) underwent revision TSA at a single institution at a mean of 4.3 years after their index surgery. Patients were retrospectively assigned to 2 cohor...
متن کاملChallenges in total ankle arthroplasty.
In the past, total ankle arthroplasty was largely abandoned due to poor survivorship most often caused by loss of bone support. High complication rates were also reported. Despite this, there is renewed interest in ankle arthroplasty and encouraging results are seen in survivorship with midterm follow-up. The procedure, however, remains more challenging than total hip or total knee arthroplasty...
متن کاملBallooning osteolysis in 71 failed total ankle arthroplasties
Background and purpose - Aseptic loosening is a major cause of failure in total ankle arthroplasty (TAA). In contrast to other total joint replacements, large periarticular cysts (ballooning osteolysis) have frequently been observed in this context. We investigated periprosthetic tissue responses in failed TAA, and performed an element analysis of retrieved tissues in failed TAA. Patients and m...
متن کاملReview Article: Polyethylene wear and osteolysis in total hip arthroplasty.
Polyethylene wear has been accepted as a major cause of osteolysis in total hip arthroplasty. Submicron particles, which are secondary to abrasive wear, migrate into the effective joint space and stimulate a foreign-body response resulting in bone loss which is mainly mediated by macrophages. Diagnosis depends on serial radiographic evaluation and frequent follow-up. Polyethylene wear and osteo...
متن کاملManagement of instability and osteolysis after total hip arthroplasty.
William J. Hozack, MD: The radiographs demonstrate a dislocated total hip arthroplasty (THA) with extensive bone lysis on both the acetabular and femoral sides. Component fixation appears intact. Closed reduction is indicated in this case, as in virtually all cases of dislocation. A dislocated THA is painful for the patient and requires immediate attention. Furthermore, there are many instances...
