The term developmental diszplázia of the hip includes different malformations of the hip: acetabular diszplázia, subluxation and dislocation. Pelvic osteotomies are common procedures in pediatric orthopaedics. They are used to correct acetabular deficiency, improve femoral head coverage, stimulate normal acetabular growth and development, and decrease high contact stresses between the femoral and acetabulum. They can be classified as reconstructive and salvage procedures. Reconstructive osteotomies can be acetabuloplasties, osteotomies with pelvic fragments displacement, redirectional osteotomies. Salvage/augmentation osteotomies are non-physiologic, indicated after bony maturity, to improve the coverage of deformed femoral heads, and to delay the arthroplasty. The most frequently used femur osteotomy is the intertrochanteric osteotomy. Operations which combine the pelvic with femur osteotomy and open reposition are called one-stage operations. At our clinic the most frequently used oseotomies under 10 years of age were the Pemberton and Dega, combined or not with femur osteotomy or open reposition. Salvage osteotomy, the Chiari technique, was used in patients older than 16 years of age.
