Surgical Treatment For Developmental Dislocation Of The Hip At Early Age

Objective:To evaluate the results of surgical treatment of developmental dislocation of the hip (DDH) in children aged from 12 to 18 months.Methods:A retrospective analysis of clinical data of 59 patients (aged from 12 to 18 months, mean 16 months), of whose 72 hips were developmental dislocation of the hip, treated with surgical treatment from 2004 to 2006. Fifty-one of the patients were female and eight were male.Thirteen patients had bilateral dislocation and fourty-six were affected unilaterally. All cases were performed surgery without traction pre-operation,53 hips were operated by open reduction and Salter innominate osteotomy; 19 hips were operated by open reduction and Pemberton transiliac osteotomy. Then 6 weeks spica cast immobilization after surgery were applied to these patients.Results:All patients had been followed up for 3 years to 5 years,50 months in average after operation. According to the modified McKay clinical criteria, Severin radiographic classification and Salter AVN diagnostic criteria., the excellent and good rate with Severin classification and modified McKay criteria were 94.4%,93 % respectively, Avascular necrosis of the femoral head occured in 2 hips(2.8%). Conclusion:Surgical treatment without preoperative traction is feasible for the management of DDH in children aged from 12 to 18 months.
