Midterm Follow-up Results of Müller Type Cemented Total Hip Arthroplasty in Our Coxarthrosis Cases

Abstract

Purpose: Total hip arthroplasty is commonly used for the treatment of diseases which manifest itself with degenerative arthritis, that is the cause of pain and disability.
Patients and methods: From November 1989 to September 1996, cemented Müller type total hip arthroplasty was performed in 43 hips of 37 patients in our clinic. 27 (72.9%) of the patients were women and 10 (27.1%) were men. The youngest patient was 45 years old and the oldest was 77 (average age was 61). Preoperative diagnosis of the cases were as follows: 15 primary hip coxarthrosis, 21 coxarthrosis secondary to congenital dislocation of the hip, 5 avascular necrosis of the hip, and 2 posttraumatic coxarthrosis. Cemented total hip arthroplasty was performed in the right hip in 13 of the cases, in the left hip in 18 cases, and in both hips in 6 cases. Shortest follow-up period as 16 months, longest was 98 months (average length of follow-up period was 48 months).
Results: Patients were clinically evaluated according to the Harris hip score: 17 (40%) hips were rated as excellent, 19 (44%) were rated as good, 6 (14%) were rated as fair, and 1 (2%) was rated as poor.
Discussion: Midterm follow-up results of cemented total hip arthroplasty in patients with coxarthrosis are satisfactory and favourable.
