Background and Purpose. The Salter innominate osteotomy has been an effective method to treat the developmental dysplasia of hip (DDH) over the past decades; however, several postoperative complications and deficiencies were reported. In this study, we evaluated outcome of a newly modified Salter osteotomy in patients presenting with DDH. Methods. We reviewed retrospectively 76 patients (90 hips) with DDH aged ≥ 18 months, who underwent open reduction and a modified osteotomy by a single surgeon. The distal osteotomy segment of pelvis was shifted anterolaterally in the amount of osteotomy cross-section, but not downwards. The mean age at surgery was 2 years and 11 months (1.5 to 16 years). Femoral shortening was conducted when necessary. The duration of operation varied between 60 and 90 minutes. The mean follow-up was 4 years and one month (range 15 months to 7 years and 9 months). All patients were followed up both clinically (based on the modified MacKay criteria) and radiologically (based on the modified Severin criteria). Results. Clinically, 94.5% of hips had excellent and good results at final follow-up, and only 5.5% had a fair condition. Radiographically, at the final follow-up 77.8% of hips were grade IA (excellent), 12.2% were grade IB, 6.7% were grade II, and 3.3% were grade III (fair). The preoperative mean acetabular index was 47.85° (41° to 59), which decreased to 17.16° (13° to 22°) immediately after the surgery (p<0.0001) and progressed to 11.24° (7° to 19°) at the final follow-up (p<0.0001). The mean initial postoperative center-edge angle was 30.3° (25° to 42°) significantly improved to 39.1 (31° to 56°) at the final follow-up (p<0.0001). Avascular necrosis of femoral head occurred in 4.4% of hips (4 patients). Conclusion. The results show that our modified Salter osteotomy is safe and associated with significant benefit for the management of patients suffering from DDH.

Summary. Hip dysplasia is the most common orthopedic problem in the practice of pediatric orthopedists. A significant problem with hip dysplasia is the divergence of nomenclature units, which is related to different points of view on the pathophysiology of the process. Contemporary conception defines hip dysplasia as a dynamic condition – “developmental dysplasia of the hip (DDH)”, which (in the absence of treatment) worsens with age and leads to the development of early hip osteoarthritis and requires hip replacement in young people. The leading macromorphological substrate of DDH is acetabular dysplasia, which is a spatial and structural change of acetabulum. For the treatment of acetabular dysplasia, conservative or surgical treatment (depending on the age of the child and the presence of previous treatment) is used. The most problematic solution is the treatment tactics for walking-age children. This is due to two factors: 1) increased loading on certain parts of the articular cartilage of the acetabulum during gait, which leads to the progression of deformity of the acetabulum and to progression of pathology; 2) changes in morphology of the intra-articular and extra-articular structures. However, better results with fewer complications are achieved after surgery. Biomechanically justified for acetabular dysplasia are pelvic osteotomies, which are divided into reconstructive and “salvage” procedures (preference is given to reconstructive procedures, which allows saving the native articular cartilage of acetabulum). Each osteotomy has its own advantages and disadvantages. When comparing three pelvic osteotomies commonly used in children (Salter, Pemberton and Dega), it is found that better results are achieved in children younger than 4 years after Salter’s osteotomy, results in older children are better after Dega’s osteotomy, and there is a high risk of femoroacetabular impingement following Pemberton’s osteotomy in the future.
