During past four years, twenty one surgical treatments were carried out on thirteen patients with aseptic necrosis of femoral head; drilling & bone nailing 1, intertrochanteric rotational osteotomy 7, cup arthroplasty 1, Moore's hip prosthesis 8, cup & socket arthroplasty 3 and total hip replacement 1.
13 patients who were followed up for more than six months after operation were clinically evaluated according to criteria of coxarthrosis of Jap. Orthop. Ass.
The patients who received intertrochanteric osteotomy showed good results in all cases. This method should be indicated as first choice of operation to early stadium with localized necrotic area. The results of hip endoprosthesis were also excellent for pain, mobility, gait and ADL. This operation was done in cases of moderate or advanced stadium in which the acetabular change was not observed.
Cup & socket arthroplasty and total hip replacement appear to be indicated to the case of severe stadium which shows narrowing of joint space and acetabular arthrotic change.
