Reduction of developmental dislocation of the hip is difficult to achieve in children after walking age and particularly in older children. In fact, at this age the important retraction of the muscles around the hip associated with a marked acetabular dysplasia and elongation of the joint capsule explain the difficulty and instability of reduction and the frequency of complications. In this study we reviewed retrospectively the clinical and radiological results of 26 developmental dislocations of the hip treated by open reduction, pelvic osteotomy and femoral shortening in 21 children aged more than 5 years. Age at surgery ranged from 5 to 11 years (mean 7.5 years) with a follow-up of 1 to 8 years (mean 2 years 7 months). According to the clinical classification of MC Kay, 17 hips had a good result while 9 hips had a fair or poor result. According to the Severin classification system 18 hips had an excellent and good radiological result. Ten hips developed an avascular necrosis of the femoral head following the reduction.

The goal of this study was to determine the indications and assess the results of surgery in the treatment of gastro-duodenal ulcers in children and adolescents. This is a retrospective study of 45 patients operated for duodenal ulcer in Sahloul Teaching Hospital (Susa, Tunisia) over period of 14 years (1988 - 2001). The study is about 41 boys and 4 girls aged between 8 and 18 years (mean age: 15 1/2 years). Surgery was undertaker in cases of bleeding ulcer (9 cases), perforation (26 cases), stenosis (7 cases), resistance to medical treatment (3 cases). The after-effects were mild in 40 cases with an average hospital stay of 6 days. Later after-effects comprised ulcerous relapse (2 cases), stricture of the pyloroplasty (2 cases), an diarrhea follwing vagotomy combined with pyloroplasty in one case. Indications of surgical treatment of gastro-duodenal ulcers in children and adolescents are, nowadays, nearly limited to complicated forms of the illness. Outcomes of surgical treatment are globally satisfactory.
