[The lag screw fixation of medial femoral neck fractures (author's transl)].
The lag screw osteosynthesis of medial femoral neck fractures is a straightforward procedure with little danger of complications. A conclusion may be drawn from the results of several authors that this method may even have a favourable influence in reducing the frequency of pseudarthrosis. In order to come to a final conclusion, however, the results of large treatment programmes would have to be studied. Fractures which are technically accurately treated allow probably full weight bearing. Lag screw osteosynthesis using more than 2 spongiosa screws in a parallel position has proved, both theoretically and practically, to be a useful method of treatment. The caudal screws increase the stability due to their position on the caudal rim of the femoral neck, while the cranial screws ensure against rotation and exertion of tensile force.
