Core Tip

Core Tip: This is a retrospective study on 36 patients with ages ranging from 8 to12 years with late stage Perthes disease (re-ossification and healing stages) underwent femoral valgus osteotomy with rotational component which result in pain relief, improved gait, and increased range of motion. In addition, relative neck lengthening is also achieved that can correct limb length discrepancy resulting from head deformity associated with the disease which for many patients may be the only problem encountered Preoperative hip arthrography is done to see the sphericity of the hip and whether there are lateral osteophytes or not.
