	abstract = {AIM: To present the 18 year survival and the clinical and radiological outcomes of the M{\"u}ller straight stem, cemented, total hip arthroplasty (THA).

METHODS: Between 1989 and 2007, 176 primary total hip arthroplasties in 164 consecutive patients were performed in our institution by the senior author. All patients received a M{\"u}ller cemented straight stem and a cemented polyethylene liner. The mean age of the patients was 62 years (45-78). The diagnosis was primary osteoarthritis in 151 hips, dysplasia of the hip in 12 and subcapital fracture of the femur in 13. Following discharge, serial follow-up consisted of clinical evaluation based on the Harris Hip Score and radiological assessment. The survival of the prosthesis using revision for any reason as an end-point was calculated by Kaplan-Meier analysis.

RESULTS: Twenty-four (15\%) patients died during the follow-up study, 6 (4\%) patients were lost, while the remaining 134 patients (141 hips) were followed-up for a mean of 10 years (3-18 years). HSS score at the latest follow-up revealed that 84 hips (59.5\%) had excellent results, 30 (22.2\%) good, 11 (7.8\%) fair and 9 (6.3\%) poor. There were 3 acetabular revisions due to aseptic loosening. Six (4.2\%) stems were diagnosed as having radiographic definitive loosening; however, only 1 was revised. 30\% of the surviving stems showed no radiological changes of radiolucency, while 70\% showed some changes. Survival of the prosthesis for any reason was 96\% at 10 years and 81\% at 18 years.

CONCLUSION: The 18 year survival of the M{\"u}ller straight stem, cemented THA is comparable to those of other successful cemented systems.},
