Periprosthetic fracture, Revision arthroplasty , BMHRAbstract
Periprosthetic fractures involving both the acetabulum and femoral neck following Birmingham mid-head resection (BMHR) arthroplasty are extremely rare. We report a case involving both without any evidence of adverse tissue local reaction and metallosis. The patient underwent single-stage revision hip arthroplasty using a cage and bone grafting. At 12-month follow-up, radiographs demonstrated fracture union and a stable implant, with the patient achieving full independent ambulation. Combined acetabular and femoral fractures in BMHR arthroplasty can occur by low energy trauma in rheumatoid arthritis. Revision arthroplasty can yield better results that fracture fixation. BMHR should be avoided in female patients who are on steroid and immunosuppression therapy.
