[Emergency screw osteosynthesis of femoral neck fractures].

27 patients with femoral neck fractures have been treated by ORIF with 3 or 4 large cancellous bone screws. The operation has been performed as an emergency intervention within 5 1/2 hours after accident. Anterior arthrotomy in direction of the long axis of the neck for evacuation of the intraarticular hematoma has been performed as a routine. Personal follow-up with X-ray documentation after 18 to 106 months (mean 29.5 months) showed complete rehabilitation in 22 patients and 2 femoral head necroses (7.4%). We conclude that these good results are due to the short interval between accident and operation as well as to the evacuation of the intraarticular hematoma, together with a stable internal fixation and functional rehabilitation.
