Abstract

See full text

A fracture fixation system comprising an elongated inner member 20 and a hollow barrel 14 adapted to receive the inner member 20. The barrel 14 includes an integral protrusion portion 15 for mating with a corresponding recess 24 on the inner member 20. The protrusion portion 15 is selectively removable by separation from the barrel 14, so that if the protrusion 15 is not removed, the protrusion 15 and corresponding recess 24 prevent rotation between the barrel 14 and the inner member 20, or alternatively, if the protrusion 15 is removed, this allows rotation between the inner member 20 and the barrel 14.
