Morselized bone autograft for high placement of acetabular component closure with hip arthroplasty revision after 3-years screws and cup loosening: A case report

Introduction and importance: Aseptic loosening in high placement of the acetabular component seriously affects the hip and femoral head loads. Surgery revision is highly recommended with defect closure in previous place. Case presentation: A-40-year-old man came with chief complaint of right groin pain and noticeable leg length discrepancy gait. The first hip arthroplasty through pseudo-acetabulum cup was done three years ago after neglected femoral head necrosis due to eight years of unknown hip dislocation in vehicle accident. On hip x-ray there is a screws and cup loosening, without any sign of infection from blood or from soft tissue which undergoes pathological and mold examination. The patient than assessed with periprosthetic aseptic loosening of hip dextra and simple total hip arthroplasty revision using true acetabulum location was done. The pseudo-acetabulum area closed with morselized bone autograft. One weeks after surgery, the wound healed properly. Hence, the patient sent to the rehabilitation. Clinical discussion: Hip arthroplasty revision of aseptic loosening in high placement acetabular component should perform by returning to anatomical acetabular position. Cancellous morselized bone autograft (MBA) was used to closed the defect formed by previous procedure. Conclusion: Revision of hip arthroplasty combined with morselized bone autograft can be considered for high placement acetabular component defect closure to provide better stability and strength in weight loads transfer.
