Biomechanical factors influencing the reduction of dislocated hips with the Pavlik harness in patients of Developmental Dysplasia of the Hip (DDH) were studied using a three-dimensional computer model simulating hip reduction dynamics in (1) subluxated and (2) fully dislocated hip joints. Five hip adductor muscles were identified as key mediators of DDH prognosis, and the non-dimensional force ...

We report the mid- to long-term (mean 20.3 years, 10 to 32.5) results of the Chiari pelvic osteotomy in patients with pre- to advanced stage osteoarthritis in dysplastic hips. We followed 163 Japanese patients (173 hips) with a mean age at surgery of 20 years (9 to 54). Overall, 124 hips (72%) had satisfactory results, with Harris hip scores ≥ 80. Satisfactory results were seen in 105 of 134 hi...

Introduction Abnormalities of the bony pelvis in exstrophy-epispadias complex (EEC) and their possible relation to hip disease are well described. However, there is a lack of information about long-term orthopedic consequences and hip function in patients with EEC. Therefore, we investigated clinical and radiological results in an EEC patient cohort after long-term follow-up. Patients and Metho...

Introduction: Congenital Zika syndrome can generate microcephaly and spastic motor syndromes, limb deformities, arthrogryposis. Hip dysplasia, associated with this syndrome, is frequent but poorly studied. Objective: To describe the radiographic alterations of hip in patients Syndrome (CZS). Methods: Observational cross-sectional cohort study. We studied 25 a serological diagnosis CZS sample 50...
