 note = {Either primary or secondary coxarthrosis, once it occurs, always takes a progressive course regardless of the variations in the speed of progression. Such progression is difficult to treat without some surgical intervention. Many operative procedures for coxarthrosis have been developed in Western countries and also in Japan. But there is no almighty single procedure which can be indicated in any type of coxarthrosis. Therefore, we can only suggest to choose a treatment which is appropriate considering such factors as age, sex of the patient, stage and status of the arthrosis and any extenuating details related to the life style of the patient. The foregoing are my comments on the current operative procesures and their indications used by myself at Niigata University Hospital. I. Procedures to preserve the joint are the favored 1st choice. 1. Procedures which are indicated depending on the stage of coxarthrosis. a. Intertrochanteric varus osteotomy is indicated in pre-or early stages of arthrosis. If the CE angle is under 20°, then also Chiari's pelvic osteotomy is indicated. b. Intertrochanteric valgus or Bombelli's valgus-extention osteotomy is indicated in advanced stages of arthrosis and sometimes in final stage of arthrosis. The shelf operation is included if coverage of the femoral head is insufficient. c. Rotational acetabular osteotomy is indicated in pre- or early stages arthrosis without the condition of coxa valga. 2. Procedures which are indicated depending on the age of patients. Intertrochanteric varus osteotomy is indicated for the majority of patients under　45 years of age, and intertrochanteric valgus or Bombelli's osteotomy for those over 46. II. Arthrodesis is indicated in the patients with unilateral coxarthrosis under 50 years of age in whom varus, valgus, Bombelli's and rotational acetabular osteotomies are not indicated. III. The joint replacement with artificial materials is indicated in the patients in whom neither osteotomy nor arthrodesis is indicated. The type of artificial joint is chosen according to the extent of osteoporosis radiologically assessed. We generally use a cementless type of total prosthesis for patients under 69 and a conventional type of total prosthesis for patients over 70. Neither bipolar nor surface replacement type of prosthesis has been used in general.},
