A RETROSPECTIVE STUDY OF THE PATIENTS WITH DEVELOPMENTAL DYSPLASIA OF THE HIP OPERATED ON IN IMAM KHOMAINI HOSPITAL OF AHWAZ FROM 1983-2001

Developmental Dysplasia of the Hip (DDH) is a spectrum of disorders of the hip that present in different forms at different ages. In case of early diagnosis in infancy it can be easily treated by pelvic Harness with a high rate of success. However, if the disorder is undiagnosed or the patient is not referred early to the physician especially after six months, surgery is often becomes necessary. Furthermore, as the child grows older not only the treatment becomes more difficult but the result is also less successful. The purpose of this study was to review of surgical procedures performed on those DDH patients who were referred to Ahwaz Imam Khomaini Hospital, after the age of six months. The results showed that between 1983 and 2001, 133 patients (120 girls and 13 boys) were operated on. The most common operation was adductor tenotomy + open reduction + innominate (Salter) osteotomy (75 cases). The age of the patients was between 6 months to 10 years. The left- and right-side involvements were 33 and 27 % of cases respectively, and bilaterally in 40 % of the cases.
