Outcome of one stage surgical correction of Developmental Dysplasia of Hip (DDH) in children older than three years of age

Aim: to study the outcome of one stage correction of developmental dysplasia of hip (ddh) in children older than three years of age methods: this prospective study was carried out at orthopaedic and spine unit of hayatabad medical complex,peshawar from july 2007 to december 2014. with non-probability consecutive sampling technique,a total of 28 hips with ddh in 22 children of age more than 3 years (03-08) were included in the study. all the patients were managed with primary one-stage triple procedure including open reduction of the hip joint,pelvic and femoral osteotomy and were followed for a minimum of one year. modified mckay's criteria was used for the clinical evaluation. the degree of dislocation of the femoral head was assessed by tonnis classification system. severin's grading system was used for radiographic evaluation,salter classification system was used for assessment of avascular necrosis. results: a total of 22 patients (28 hips) were operated for developmental dysplasia of the hip. the mean age of the patients at the time of ward admission was 4.4 years. the mean follow-up period was 23 months. the average acetabular index pre operatively was 42 degrees and it to 28 degrees post-operatively. according to modified mackay's scoring system system 14 (50%) hips were excellent (stable hips with pain free full range of motion,no limp and negative trendeleburg sign),09(32%) hips were good,03(11%) hips were fair and 02 (07%) hips were poor. conclusion: one stage,triple procedure of open reduction,femoral shortening and salter osteotomy is a very safe and effective method for the treatment of ddh in older children.
