| Summary: | © Journal Of The Medical Association Of Thailand. Background: The use of a cemented Moore’s endoprosthesis is a very common procedure for osteoporotic hip fracture treatment in Thailand due to its relatively low cost, low dislocation rate, and short operating time. Recently, increasing concern over acetabular erosion has ignored the use of this implant. Objective: To analyze the effects of acetabular erosion after Moore’s endoprosthesis on the functional outcomes. Materials and Methods: Fifty patients (male 23:female 27, age 61 to 93 years) who undergone Moore’s unipolar hemiarthroplasty (HA) due to an osteoporotic femoral neck fracture in Chiang Mai University Hospital between 2010 and 2012 were included in the present retrospective cohort study. The effects of acetabular erosion on Harris Hip Score (HHS) functional outcomes were analyzed. Results: The acetabular erosions were observed about 22%, 46%, and 59% after the first 12 months, 24 months, and 36 months of the implantations, respectively. Half of the patients after Moore’s HA had acetabular erosion at 30.9 months. Patients 75 years or older increased 1.6 times the risk of acetabular erosion after three years follow-up. However, occurrence of acetabular erosion did not result in worse outcomes at three years after the replacements (p=0.818). Conclusion: Physicians can overlook acetabular erosion after Moore’s HA and concentrate on surgical techniques that closely restore the native hip geometry with Moore’s prostheses. |
