We analyzed 30 Bateman Universal Proxymal Femur (UPF) endoprostheses by clinical and radiographic examination. Of these 24 had had subcapital fracture (group 1), and 5 had had aseptic necrosis of the femoral head and 1 was of a bone tumor of the femoral head (group 2) . The patients were followed up over 3 years (mean 4 years, 3 months) . One had developed infection. The results in the 30 hips were evaluated by the JOA hip score; group 1 had a score of 81.3, and group 2 are of 83.3.
Radiographic evalution showed that no patient had proxymal migration, 5 patients had distal migration, 5 patients had ectopic ossification, and 8 patients had clear zone enlargement.
We concluded that the Bateman UPF is useful in the treatment of subcapital fracture in older patients and for those with aseptic necrosis of the femoral head.
