Outcome of Allogenic Bonegrafting for Acetabular defect (Protusio Acetabulum)following Total Hip Replacement A Case Report

The use of allografts and autografts in the management of acetabular defects has been reported with varying results. Trabecular metal is an expensive option for correcting defects. This study aims to assess the outcome of allogenic bonegrafting following hip replacement.Materials and Methods- A 52 years old Male patient diagnosed as Transcervical Fracture neck of femor (8 weeks old) initially treated by local bone setter. We planned for uncemented total hip replacement for this patient. Cup size of 50mm femoral stem size of 1 (S N). Following procedure post op X-Ray shows radiological evidence of Protusio acetabuli ( Medial acetabular cup crosses Ilio Ischiel line ). For that we planned for Allogenic bone grafting (Taken from preserved femoral head) using same prosthesis. Bone graft taken from preserved femoral head packed and gentle reaming done. Results- Patient followed up for the past 8 months. Follow-up XRay shows good incorporation of bone graft, good range of motion, no graft lysis, and no change in the cup inclination and no evidence of infection. Patient was pain free at all times of follow up with maintenance of graft and implant position.
