Interposition arthroplasty of the hip is to create a new joint by interposing an inert and durable substance between the reshapened ends of the femoral head and acetabulum, usually for the treat meat of the primary and secon~ary osteoarthritis of the hip. The major goals of arthroplasty of the hip-are to relieve pain; ´restore joint motion, correct deformity, and to provide stability of the joint.
We reviewed the follow-up -results of 23 Smith-Patersen vitallium cup arthroplasties in a cons:cutive series of 20 patients with various arthritides of the hip, who were treated at the National Medical Centel between January 1962 and December 1970. Average duration of follow-up was 2 year and 10 months.
1. Male to female ratio .was 12 ~ 8. Averaga ags of the patients was 30 years.
2. Seven patients had rheumatoid arthritis or ankylosing spondylitis and five patients had ankylotic hips. Throe patients had primary osteoarthritis and another thiee osteoarthritis secondary to Legg-Calve-Perthes disease. There were one case each of tuberculous arthritis and traumatic dislocation.
3. Average duration of admission was 7 weeks.
4. Weight bearing was started gradually at 12 weeks post-operatively in majority of the cases.
5. Overall results of the 20 patients were satisfactory in 12 (60%), and unsatisfactory in 8 (40%).
6. Results of cup arthroplasty in patients with primary osteoarthriti`s -and osteoarthritis secondary to Legg-Calve-Parthes diseasewere satisfactory in all 6 cars, .but wera unsatisfactory in 5 out of the 7 cases of the rheumatoid arthritis and ankylosing spondylitis.
7. Three patients with bilateral cup arthroplasties yielded poor results.
B. Complications included .eight infections and one each of early dislocation of the cup and periarticular new bone formation.
