Total hip arthroplasty on dysplastic hip : Assessment of difficulties and results
Year: 2026
Type: article
Abstract: Developmental Dysplasia of the Hip (DDH) is a major cause of early-onset osteoarthritis in young adults and poses significant technical challenges when performing a Total Hip Arthroplasty (THA). This study reports the experience with ten patients operated on for end-stage osteoarthritis on a dysplastic hip, predominantly severe forms of Crowe type III and IV. Preoperative clinical and radiological evaluation allowed for precise planning, and all patients underwent a dual-mobility THA via a posterolateral approach. Anatomical acetabular reconstruction required bone grafting in 40% of cases, while a femoral shortening osteotomy was performed in 20% of the interventions. Postoperative results show significant functional improvement with a mean Harris score of 84 points, disappearance of pain, and recovery of walking distance. No major complications were observed. This series confirms that, despite the inherent anatomical complexity of DDH, THA provides very good functional outcomes when the surgical strategy is adapted and rigorous
