Delayed cementless total hip arthroplasty for neglected dislocation of hip combined with complex acetabular fracture...

Total hip arthroplasty (THA) for an untreated acetabular fracture is technically challenging and the long-term result is not so favorable. A 45-year-old female patient with untreated column and comminuted posterior wall fracture of the acetabulum was treated in our institution by reconstruction of the posterior wall using iliac strut autograft and plate stabilization of the posterior column with cancellous grafting and cementless THA in a single stage. At 3 years?follow-up, the patient was independently mobile without limb length discrepancy. Radiological evaluation showed well integrated components and bone grafts. No evidence of aseptic loosening or osteolysis was found. This report aims to emphasize that bony acetabular reconstruction allows the use of primary hip components, which improves prosthesis longevity and preserves bone stock for a future revision.
