A total of 351 femoral neck fractures were treated from 1986 to 1987.
The fractures were classified into three groups according to Pauwels.

rnal fixation was performed, while in 16% total hip endoprosthesis was
done. Of these patients 254 were reexamined three years later. In onl
y 24.4% of the 254 patients were poor results - necrosis of the femora
