Bone fixation apparatus and method

摘要

A bone fixation apparatus comprises an extramedullary component, an intramedullary component, and a fastener configured and dimensioned to interconnect the extramedullary component and the intramedullary component. The fastener has a head portion and a shank portion. The head portion is configured and dimensioned to be received in the extramedullary component. The shank portion is configured and dimensioned to be received in the intramedullary component. The fastener has a first longitudinal axis extending through both the head portion and the shank portion. The extramedullary component has a second longitudinal axis. The extramedullary component also includes an elongated surface defining an opening through which the shank portion of the fastener passes when the shank portion is received in the intramedullary component. The opening has a V shape. The V shape is oriented transverse to the first longitudinal axis and to the second longitudinal axis.
