Displacement of subcapital fractures during internal fixation: a real problem?
The potential for femoral head rotation occurring during insertion of a compression hip screw has been investigated. Rotation to up to 30 degrees has been demonstrated, and was not visible on an image intensifier. The insertion of a guide-wire parallel to a hip screw does not control rotation adequately. Small threaded pins do not cause femoral head rotation.
