Unrecognised joint penetration in treatment of femoral neck fractures.
Screw devices used to treat fractures of the femoral neck are usually positioned under image-intensifier control, using anteroposterior and lateral views. The volume projected by these views is over 27% larger than the femoral head; the tips of screws so placed may be outside the femoral head. This can be avoided by placement within the central two-thirds of the head: we have designed a template which can confirm safe placement.
