[Primary Zweymuller total hip arthroplasty for osteoarthritis secondary to congenital acetabular dysplasia].

OBJECTIVE: To evaluate the effectiveness of Zweymuller prothesis in replacing osteoarthritis secondary to congenital dysplasia of the hip. METHODS: From January 1996 to June 2000, Zweymuller prothesis was used to reconstruct 32 hips in 29 patients with congenital acetabular dysplasia(3 bilateral cases). All patients were female. According to the classification of Perner, 19 hips belonged to type I, 7 type II, 5 type III, and 1 type IV. The mean follow-up period was 27.5 months (6-53 months). The preoperative Harris hip score ranged from 25 to 59(average 44.5). RESULTS: The pain was completely relieved, and the Harris hip score ranged from 63 to 97(average 85). CONCLUSION: We consider that the Zweymuller total hip arthroplasty provides stable fixation of the cup in the presence of moderate acetabular dysplasia without structural bone grafting or cementing.

[Cementless implantation of Zweymueller-Endler total endoprosthesis of the hip. Clinical, radiologic and scintigraphic follow-up of 2 years].

Sixty-four patients with cementless Zweymueller-Endler total endoprostheses of the hip underwent follow-up postoperatively for 2 years. In 3 patients loosening or infection occurred. In 61 patients no complications were observed. However, in 74% of these patients increasing activity uptake at the tip of the shaft was found by scintigraphy. This was associated with hypertrophy of the corticalis and/or with a marrow cavity reaction, observed radiologically. The results show that scintigraphic evaluation of cementlessly implanted Zweymueller-Endler endoprostheses of the hip must be interpreted differently compared to isoelastic or to cemented prostheses.
