Long-term results of an anatomically implanted hip arthroplasty with a short stem prosthesis (MiniHipTM)

AIM: system. Elderly patients were not excluded from this study, thus the mean age at the time of surgery was 59.3 years (range 32 to 82 years). Surgery and the follow-up assessments were performed at two Centers. Up until now, the mean follow-up was 112.5 ± 8.2 mo. The Oxford Hip Score (OHS) and the Hip Dysfunction Osteoarthritis and Outcome Score (HOOS) was assessed pre- and each year after surgery. The clinical follow-up was accompanied by standardized a.p. and axial radiological examinations. Periprosthetic lucencies, hypertrophies within the Gruen zones one to fourteen were assessed. A subsidence of the stem was investigated according to Morray and heterotopic ossifications were assessed according to Brooker. RESULTS: ., bony hypertrophies or bone appositions of more than 2 mm, were also not detected. CONCLUSION: is a reliable partial-neck retaining prosthesis with good a clinical long-term outcome in younger as well as elderly patients.
