Objective: The aim of this study was to evaluate the results of open reduction and Salter Innominate Osteotomy (SIO) for the treatment
of developmental dysplasia of the hip (DDH).
Materials and methods: In this study, the results of the open reduction and Salter Innominate osteotomy in 56 hips (50 patients: 44 girls,
6 boys) who had been operated on Bakırköy Dr. Sadi Konuk Training and Research Hospital, Department of Orthopaedics and
Traumatology, between January 2000 - January 2007 was evaluated. At the time of surgery, mean age of the patients was 22.4 months
(11-60). Forty-four of the patients were unilateral and 6 of them were bilateral. After routine preparations standard Salter Innominate
Osteotomy was performed without preoperative traction. Adductor and iliopsoas tenotomy were added if it was needed at the
intraoperative evaluation. Femoral derotation or shortening were not performed. Postoperatively pelvipedal cast was applied for 45 days
and hip abduction brace (Dennis-Brown type) was worn for another 45 days. All of the patients were evaluted after a mean of 21.6 months
(7-44) follow-up. The modified Mac Kay criteria were used for the clinical and Severins criteria was used for radiological evaluation, and
the Kalamchi - MacEwen classification was used for the assessment of the developed avascular necrosis of the femoral head.
Results: The mean follow up of the patients was 21.6 months (7-44). Of the 56 hips who were operated, 51 of them (91.1%) were group I
(very good), 4 of them (7.1%) were group II (good), 1 of them (1.8%) was group III (average) clinically. Of the 56 hips, 44 of them (78.5%)were
group I (very good), 8 of them (14.3%) were group II (good), 3 of them (5.4%) were group III (average), 1 of them (1.8%) was group IV (bad)
radiologically. Avascular necrosis (3 hips 4.92% and type 1) and dislocaton (1 hip 1.64%) were detected postoperatiely.
Conclusion: The Salter Innominate Osteotomy was an effective surgical treatment technique for the DDH patients of 18-60 months age
and the results of our study were parallel with the successfull results of the literature.
