Nowadays, hip dysplasia is recognized and treated mainly conservatively due to good screening program and early detection. There are still some cases found after first year of life, in later childhood and in adults. These cases are treated with pelvic osteotomies to improve femoral head coverage and joint stability and to decrease the hip stress with the final goal to preserve the joint in longer term. There are three subtypes of pelvic osteotomies. The ones pertaining to first type are redirectional osteotomies, which are incomplete osteotomies with the aim to reduce overall volume and redirect the acetabulum by a hinge located between triradiate cartilage and pubic symphysis. This type in-cludes Salter, Pemberton, Dega and San Diego osteotomies. The osteotomies pertaining to the second type are reorientational osteotomies, which are complete osteotomies with the aim to reorient the whole acetabulum. This type includes periacetabular and triple osteotomies. The osteotomies per-taining to the third type are salvage osteotomies which enlarge the acetabulum and medialise the hip center in arhritic and/or incongruent joint and are performed in hips in which the reorientational osteotomy is contraindicated. This type includes shelf and Chiari osteotomies. In University Medical Centre Ljubljana, most of the above-mentioned osteotomies are being performed, however, yearly numbers are small. Redirectional osteotomies have been performed for many years in the Pediatric orthopaedic department and yearly number is under 10 cases. Reorientational osteotomies on young adults are made through minimally invasive approach for periacetabular osteotomy described by Soebbale at al. (2015). In selected cases, electromagnetic surgical navigation system is used for more precise positioning of the acetabular fragment.
