Pelvic osteotomy is a surgery for correcting acetabular deformity, which causes incomplete coverage of the femoral head or biomechanically abnormal load to the hip joint. Pelvic osteotomy can be divided into two categories: reconstructive or realignment osteotomy and salvage osteotomy. Reconstructive osteotomy can be performed to correct the dysplastic hip with good congruency, and include most pelvic osteotomies, except Chiari osteotomy. Among these, Bernese osteotomy, rotational acetabular osteotomy, and periacetabular rotational osteotomy are commonly being used. Salvage osteotomy, which include Chiari osteotomy only, can be performed to increase the coverage of the femoral head of hip joint with joint incongruency due to the severely deformed femoral head and acetabulum or advanced osteoarthritis. Chiari osteotomy is a kind of arthroplasty reducing the pressure applied to the head, and increasing the bone coverage on the upper part of the femoral head. It is effective in reducing hip pain and slowing degenerative changes; however, as the surface is covered by fibrous cartilage, it is vulnerable to degenerative changes. The pelvic osteotomy is a very important and useful surgical technique to preserve joints, despite being a difficult procedure that is technically demanding.
