This is a report of the results of the clinical application of China-made Austin-Moore artificial femur prothese on 14 cases of femur head and femur upper section desease. Alien bone was used together with artificial femur protheses in two of these cases. Of the 14 cases, 7 were male and 7 female. The oldest was 75, and the youngest 39. The longest follow-up time was 2 years and 3 months, the shortest 5 months. One case died seven months after the operation due to fungus meningitis. One case of ...
