Results of open reduction and Salter innominate osteotomy for developmental dysplasia of the hip

We aimed to evaluate the clinical and radiological results of open reduction (OR) and Salter innominate osteotomy (SIO) for patients with developmental dysplasia of the hip (DDH). In this study, the results of 45 instances of OR and SIO treatment on 36 DDH patients between 2004 and 2012 were evaluated retrospectively. 28 (77.77%) of the patients were female and 8 (22:33%) of them were male. The mean age was 28.8 (18-55) and the mean follow-up period was 41.8 months (6-101). A recovery percentage was calculated by measuring the acetabular index on plain radiographs recorded before surgery, immediately after surgery, and final checkup. During patients’ final checkup, the clinical evaluation was performed according to a modified version of McKay’s criteria and the evaluation of the range of the joint motion was carried out according to the Trevor-Johns-Fixen scoring system. The acetabular index values recorded from patients’ hips had an average of 39.9 (35-47) degrees before the operation, but had a mean of 30.5 (20-35) degrees after the operation and an average of 18.5 (10-30) degrees during the final checkup. Clinically, excellent results were obtained in 22 hips (49%), good results were obtained in 17 hips (38%), and satisfactory results were obtained in 4 hips. Two of the patients could not be evaluated since they could not be mobilized due to cerebral palsy. Re-dislocation emerged in 3 hips (6.6%), deep infection emerged in 1 hip (2.2%), and a supracondylar femur fracture emerged for 1 patient (2.2%). OR and Salter’s innominate osteotomy is a highly effective surgical technique in the treatment of DDH cases that have lasted more than 18 months.
