Comparison of the Results of Core Decompression and Sugioka’s Transtrochanteric Rotational Osteotomy for Osteonecrosis of the Femoral Head

stage osteonecrosis of the femoral head (ONFH), the factors normally considered are the progression of the disease and the patient’s age. Although most clinicians agree that the focus, when first treating patients under 50 years of age, should be on preserving the joint, there is significant controversy as to the appropriate procedure in any given case. Core decompression is one of the joint salvage surgical procedures that has generated a great deal of controversy among researchers, who dispute both its effectiveness and the incidence of complications. Despite this controversy, core decompression is the most widely used method, based on its being a relatively simple surgical techniques and the widespread acceptance of its efficacy in treating diseases in the earlier stages. A transtrochanteric rotational osteotomy, which is also called the Sugioka Operation owing to its introduction by Sugioka et al. in 1978, is widely recog-
