Effectiveness of structural bone graft in total hip arthroplasty for Hartofilakidis type Ⅱ developmental dysplasia of the hip

To summarize the effectiveness of acetabulum reconstruction with autologous femoral head structural bone graft in total hip arthroplasty (THA) for Hartofilakidis type Ⅱ developmental dysplasia of the hip (DDH). A clinical data of 24 patients (27 hips) with Hartofilakidis type Ⅱ DDH, who underwent acetabulum reconstruction with autologous femoral head structural bone graft in primary THA between October 2012 and October 2020, was retrospectively analyzed. There were 3 males and 21 females, with an average age of 40 years (range, 20-58 years). The body mass index was 19.5-35.0 kg/m² with an average of 25.0 kg/m². There were 21 cases of unilateral hip and 3 cases of bilateral hips. The hip Harris score was 51.1±10.0. The leg length discrepancy of unilateral hip patients was (19.90±6.24) mm. The intraoperative blood loss, wound healing, and complications were recorded. The postoperative bone union, coverage rates of acetabular prosthesis and bone graft, and aseptic loosening of the prosthesis were evaluated based
