Effects of different pelvic osteotomies on acetabular morphology in developmental dysplasia of hip in children

Abstract

Developmental dysplasia of hip seriously affects the health of children, and pelvic osteotomy is an important part of surgical treatment. Improving the shape of the acetabulum, preventing or delaying the progression of osteoarthritis is the ultimate goal of pelvic osteotomies. Re-directional osteotomies, reshaping osteotomies and salvage osteotomies are the three most common types of pelvic osteotomy. The influence of different pelvic osteotomy on acetabular morphology is different, and the acetabular morphology after osteotomy is closely related to the prognosis of the patients. But there lacks comparison of acetabular morphology between different pelvic osteotomies, on the basis of retrospective analysis and measurable imaging indicators, this study predicted the acetabular shape after developmental dysplasia of the hip pelvic osteotomy in order to help clinicians make reasonable and correct decisions and improve the planning and performance of pelvic osteotomy.

Mechanical osteoarthritis of the hip in a one medicine concept: a narrative review

“…Femoral procedures such as varization, femoral shortening, and derotation osteotomies [ 18 , 72 ] have special importance in decreasing femoral head forces and the predisposition for avascular necrosis [ 72 ]. Pelvic surgeries like triple osteotomy [ 18 , 69 , 72 ], juxta-articular double osteotomy [ 73 ], Salter innominate osteotomy [ 74 ], and periacetabular surgeries such as Dega transiliac osteotomy [ 75 ], Pemberton pericapsular osteotomy [ 76 ], and Bernese periacetabular osteotomy [ 77 ]), improve in general acetabular femoral head coverage, increase the cartilage weight bearing area and reduce local overload, preventing the development of OA [ 78 ]. Salvage procedures are other non-conservative options mainly used to relieve pain in cases of irreversible cartilage degeneration and to delay hip arthroplasty fitting [ 72 ].…”
