It is reported of 81 patients (average age: 86.1 years) with fractures of the proximal femur who have been treated with Ender-nails. The results of the preoperative state justify the immediate operation. Local complications were found in 29.6% out of the cases, mainly outcracks of the corticalis in 14.8%. The hospital letality was 19.8%. In 35 patients a follow-up examination was done after an average period of 20.2 months. Before operation about 75% of patients had a very good or good degree of mobility, in follow-up examination the rate was about 50%.
