Abstract:
Avascular necrosis of the femoral head is generally localized in the anterosuperior aspect of the head. The posterior part of the head often retains a normal, smooth contour containing healthy cartilage even in much advanced cases. Because of this anatomical localization of the lesion, Y. Sugioka has devised a transtrochanteric rotational osteotomy in young and middle-aged person, which reduces the weight-bearing force on the necrotic area, and transfers shearing forces to the healthy posterior cartilage of the femoral head to prevent progressive collapse of the articular surface and improve alignment when articular collapse followed femoral head subluxiation. The authors reviewed 13 cases of Sugioka operation, performed at the Department of Orthopedic Surgery, Seoul National University Hospital during the period from December 1983 to Feburary 1986 and the following results were obtained. 1. There were 11 males and 1 female. The average age of the 13 cases was 33.3 years. 2. In all the cases of Grade I and Grade II hips, there was not progressiveness of necroticarea of femur heads. 3. By U.C.L.A. hip rating system, preoperative mean scores of pain, walking ability, function and activity were 2.5, 5.7, 4.8 and 4.3, respectively, while postoperative scores of these were increased to 7.7, 9.5, 8.4 and 7.8, respectively. 4. Average ranges of motion of hip joint were increased more postoperatively than preoperatively.
