Apparatus and method for use of the apparatus for fracture fixation of the distal humerus

摘要

A system for fixing fractured bone portions of a distal humerus in position with respect to one another. In one embodiment, the system includes a plate portion, a projection portion, and a fixation post. The plate portion includes a surface for contacting a posterior portion of the distal humerus adjacent one of a lateral side and a medial side thereof. The projection portion extends outwardly from the plate portion and includes an aperture for receiving the fixation post. The fixation post includes at least one fenestration, and extends from adjacent the one of the lateral and medial sides of the distal humerus to adjacent the other of the lateral and medial sides of the distal humerus.

1. A system for fixing fractured bone portions of a distal humerus in position with respect to one another, the system comprising:
a plate portion including a first surface, an opposite second surface, a first end, a second end, and a length between the first and second ends, the second surface being configured to contact a posterior portion of the distal humerus adjacent one of a lateral side and a medial side thereof; a projection portion extending outwardly from the second surface, the projection portion including a third surface, an opposite fourth surface, and an aperture therethrough between the third and fourth surfaces, the fourth surface being configured to contact the one of the lateral and medial sides, and the aperture being configured to receive a fixation post; the fixation post including a head portion, a shaft portion, a first end, an opposite second end, and plurality of fenestrations provided in the shaft portion, the shaft portion extending from the head portion to the second end, the head portion being configured to engage the aperture formed in the projection portion, the shaft portion being configured to engage the fractured bone portions and to extend from the one of lateral and medial sides to adjacent the other of the lateral and medial sides, each of the fenestrations having a longitudinal axis, wherein the longitudinal axes are not parallel to each other, and each of the fenestrations being configured to receive a cross member; and each of the cross members having a shaft portion, at least a portion of the shaft portion of each of the cross members being received in one of the fenestrations to attach the fixation post to each of the cross members, each of the cross members being configured to engage the fractured bone portions adjacent the fixation post, wherein, when the fixation post is positioned with respect to the fractured bone portions, and each of the cross members is attached to the fixation post, the fixation post and the cross members serve in stabilizing the position of the fractured bone portions.
