Restoration of Proximal Femoral Anatomy during Total Hip Arthroplasty for High Developmental Dysplasia of the Hip: An Original Technique

Objective To introduce a modified osteotomy method for proximal femur reconstruction (PFR) in total hip arthroplasty (THA) for high developmental dysplasia of the hip (DDH). Method A retrospective study was performed in a series of 24 patients (26 hips) with Crowe III/IV DDH who underwent THA and simultaneous PFR. We used an animated video to illustrate and help understand the procedure for this technique. Patients were reviewed clinically and radiographically with an average follow‐up of 31 months. The Harris hip score (HHS) was recorded preoperatively and at 3 and 12 months postoperatively. Results All patients achieved primary bone union. No revision was needed up to the latest follow‐up. One patient had a dislocation due to self‐fall and received manual reduction under general anesthesia. No patient had intraoperative femoral fractures, sciatic nerve injury, or infection. The mean HHS improved from 33.48 ± 9.06 preoperatively to 84.61 ± 4.78 immediately after surgery and 90.84 ± 4.96 at 12 months. Conclusion Proximal femur reconstruction is a simple and practical technique for femoral remolding during THA in patients with high DDH.
