The outcomes of salter innominate osteotomy in the treatment of developmental dysplasia of the hip [Geliçimsel kalça displazisinin tedavisinde salter'in i?liyak osteotomisi sonuçlarimiz]

Abstract

Objective: The aim of treatment in developmental dysplasia of the hip (DDH) is the reduction of the hip joint and by maintaining the reduction, enabling the physiological development of the hip. Salter innominate osteotomy (SIO) is one of the surgical methods that is used in certain age groups with this aim. In this study, we examined the results of the SIO technique that we had used in the treatment of patients at a certain age. Material and Methods: Seventy-nine hips in 61 patients who underwent SIO due to DDH between the years 1994-2002 were included in the study. The acetabular angle and the center-edge angle were measured before the procedure and at the final follow-up visit in all patients. Clinical assessment was made using McKay's criteria in the follow-ups. Radiological assessment was made using Sever criteria. In addition, Kalamchi and MacEven radiological criteria were used in assessing the presence of aseptic necrosis. Results: The mean age was 29.2 ± 12.7 (16-84) months at the time of operation and 91.2 ± 37.2 (30-180) months at the final follow-up visit. Before the operation, the mean of the acetabular angle was 38.7 ± 5.9, whereas at the last follow-up the mean of the acetabular angle and the center-edge angle were 20.9 ± 7.6 and 35.1 ± 11.3, respectively. Patients were followed for an average of 60.5 ± 35.1 (6-107) months. In the follow-up visits, redislocation in one hip (1.3%), subluxation in 2 hips (2.6%), deformation in the acetabulum in 2 hips (2.6%), fibre migration in 3 hips (3.9%) and a broken femur resulting from taking off the plaster of the lower extremity in 1 patient (1.3%) were determined. In addition, avascular necrosis (AVN) was present in 10 hips (12.6%). Clinical assessment revealed that 36 hips (45.5%) were excellent, 28 hips (35.5%) were good, 12 hips (15.1%) were fair and 3 hips (3.9%) were poor. Conclusion: We saw, by assessing clinical, radiographic results and complications, that the SIO technique was effective in the surgical treatment of patients with DDH in the 1.5-6 age group.
