A 47-year-old woman was presented to the emergency department. The limb of the patient was shortened, and her hip was mildly flexed, adducted, and internally rotated. Initially, the patient was misdiagnosed as posterior hip dislocation. However, after careful history taking and radiologic evaluation, her final diagnosis was developmental dysplasia of hip, which was a sequelae of poliomyelitis.

Introduction
 Developmental dysplasia of the hip (DDH) includes femoral head subluxation or dislocation and/or acetabular dysplasia. The gold standard treatment for DDH during walking age remains controversial. Treatment modalities that have been proposed to treat after are osteotomy and pelvic osteotomy. aim this study was assess radiographic results surgical age.
 Case Presentation&...

Osteoarthritis secondary to developmental dysplasia of the hip is a surgical challenge because of the modified anatomy of the acetabulum which is deficient in its shape with poor bone quality, torsional deformities of the femur and the altered morphology of femoral head. Particularly in Crowe type III and IV, additional surgical challenges are present, such as limb-length discrepancy and adduct...

background: the prevalence of neglected developmental dysplasia of the hip (ddh) has been decreasing. nowadays, the disease is rarely seen in walking age children. the purpose of this study is to assess the results of simultaneous osteotomy of femur and pelvic bones in such children. method: we performed a retrospective study on 30 children aged 3.8±0.9 (range: 1.5-7) years old, with ddh who un...
