[Late results of the operated patients with femoral neck fractures. results of the a-o technique and the endoprosthesis from 3 to 5 years after operation (author's transl)].

The late results of 133 operatively treated patients with femoral neck and trochanteric fractures were evaluated. The series consisted of 86 women and 47 men, 72 femoral neck fractures and 61 trochanteric fractures. 99 patients were treated by A-O osteosynthesis and 34 by endoprosthesis. The average age of the group with osteosynthesis was 71 and of the group with endoprosthesis 76 years. From 3 to 5 years after the operation the nailing results of the patients with femoral neck fractures were poor in 7.1 and with trochanteric fractures in 15.4 per cent. During the same observation period the results of the patients treated with endoprosthesis were poor in 14.3 per cent. There were no statistically significant difference between the A-O group and the endoprosthesis group with femoral neck fractures. Between the mortality of the nailed patients with femoral neck fractures and the endoprosthesis group there was no statistically significant difference.
