Introduction. Developmental dysplasia of the hip (DDH) represents one of common diseases of the locomotor system. Late discovery and inadequate healing of this defect leads to serious disability in the best years of human life. Objective. The aim of this study was to analyze the quality of functional and anatomic restitution of the diseased hip, depending on the age of the patient at the time of surgery. Methods. Our retrospective study was developed on 78 children surgically treated for DDH. The examiners were distributed in three groups according to age in which they had been operated. The data were produced on the basis of full-scale medical documents for each patient. Results. We analyzed and compared anatomic and functional results of surgeries treating DDH in the group of examiners. On examination, we got data that the most prevalent were distorted gait, inequality of the legs and positive Trendelendburg’s sign in the group of children who had been operated in the oldest age. The patients who were surgically treated in older age had worse postoperative results in aspect value angle of flexion and abduction in treated hip, higher frequency in manifesting pain and asymmetric gait. Better corrective results on aspect of dimension of the colodiaphyseal and Hilgenrainer’s angle will be obtained if DDH treatment is conducted in younger age of patients. In 94.95%, the patients were treated with Salter innominate osteotomy of pelvis with osteotomy of the femur involving its shortening and reverse rotation. Preoperative treatment with Pavliks harness was provided in 44.02% children, with abduction of Hilgenrainer’s apparatus in 2.6%, with abductions “Niva” slips in 2.6% and preoperative extension in 28.2%. Conclusion. The surgical treatment of DDH in the observed patients done at the earlier age of growth resulted in the evidently better anatomical and functional results at postoperative observation.
