Objective: We hypothesized that as the patient’s age increases, the outcomes of Salter pelvic osteotomy (SPO) get worse. This studyaims to compare the results of surgery in developmental dysplasia of the hip (DDH) with at which age SPO is performed.Patients and Materials: Forthy six hips of 36 patients with at least 1 year of regular radiological and clinical follow-up were includedin this study. The patients were retrospectively divided into three groups, group I for ages between 18 months and 4 years, group IIfor ages between 4 and 6 years, and group III for ages over 6 years. The clinical and radiological results of the patients were comparedbetween groups.Results: At the time of surgery, the mean age of patients was 4.51 years (18 months-11 years). After a mean follow-up of 72.7 months;although there was no statistically significant difference between groups according to Severin’s radiological criteria, it was observedthat the success of the clinical outcome decreased and the avascular necrosis (AVN) rates increased in children who were operatedafter the age of 6 years.Conclusions: Although, SPO was an effective treatment option for patients with DDH after the age of walking, it might cause adecrease in the success of clinical outcomes and an increase in AVN after 6 years of age.
