The biomechanical differences of rotational acetabular osteotomy Chiari osteotomy and shelf procedure in developmental dysplasia of hip

摘要

BackgroundRotational acetabular osteotomy (RAO), Chiari osteotomy and shelf procedure are important treatments to delay the progression of osteoarthritis in developmental dysplasia of hip (DDH) patients, but their biomechanical differences are still unknown. This study was to evaluate the different biomechanical changes of hip joint after these three surgeries.
