The Outcome of Salter Innominate Osteotomy for Developmental Hip Dysplasia before and after 3 Years Old.

ABSTRACT

BACKGROUND: Developmental dysplasia of the hip (DDH) is one of the most important and challenging conditions in the field of pediatric orthopedics; if not diagnosed and treated in time, it would lead to remarkable morbidity. Methods of treatment based on the patient's age can vary. The aim of this study is to compare the outcomes of Salter osteotomy surgery in two groups of patients under and over three years old. METHODS: In this retrospective study, medical records of patients who had undergone innominate Salter osteotomy, within the past ten years, due to non-pathological DDH were collected. Mean follow up of all patients is 70.28 months (min=25, max=118). RESULTS: eventy patients were selected including 85 operated hips. Radiological satisfaction based on modified Severin score system rate was 86% and 85% for lower three years old group and second group, respectively. In clinical assessment, it was found that results in 82% of the patients under 3 years old and 82.9% of patients older than three years old were satisfactory. There was no statistically significant difference between the two groups based on Modified MacKay criterion. CONCLUSION: Results in both groups of patients under and over 3 years old were found satisfactory. Difference in patient satisfaction rates based on clinical and radiological outcomes was not statistically significant between the two groups. It should also be noted that complications such as redislocation and deep wound infection would cause poor clinical and radiological outcomes.
