Abstract : Hip dysplasia is a structural abnormality of the hip joint resulting from altered morphology of the acetabulum, the proximal femur, or both, which leads to insufficient coverage of the femoral head and abnormal joint loading. Advances in neonatal and pediatric screening programmes, particularly clinical and ultrasound-based protocols, have contributed to earlier diagnosis and a reduction in the incidence of severe, untreated dysplasia progressing to early osteoarthritis in many populations. However, residual or late-presenting dysplasia in adolescents and adults remains a major cause of pain and early hip degeneration, often necessitating joint-preserving surgery or, in advanced cases, total hip arthroplasty. Among available surgical options for symptomatic acetabular dysplasia, the Roy-Camille shelf arthroplasty represents a conservative, extra-articular procedure that augments acetabular coverage using an iliac crest bone graft. Compared with more complex reorienting osteotomies such as periacetabular osteotomy, shelf procedures are technically less demanding, preserve the integrity of the pelvic ring, and are associated with relatively rapid postoperative recovery and low major complication rates when performed in appropriately selected patients with minimal osteoarthritis and a congruent joint. In this context, the present work reports the case of a 35-year-old woman with symptomatic right acetabular dysplasia treated by Roy-Camille shelf arthroplasty. The case is used to illustrate the indications, surgical technique, and early postoperative course, and is complemented by a literature review comparing the advantages, limitations, and long-term outcomes of shelf arthroplasty with other hip-preserving procedures for dysplasia.
