Bone fixation device and method

摘要

In a method and system for corrective surgery of a bone, a bone is cut into a first bone segment and a second bone segment. A plate is positioned over the first bone segment and the second bone segment such that at least one member of the plate is positioned to engage the second bone segment. The at least one member of the plate is inserted into the second bone segment. At least one bone screw is screwed into the first bone segment through at least one compression slot of the plate causing an application of compressive force to secure the first bone segment and the second bone segment to form a corrective construct. The at least one member is positioned at an angle or an offset from the second plate segment.

主权项

1. A bone fixation system, comprising:
a plate comprising:
a first segment comprising:
at least two members each including a first portion and a second portion angled with respect to the first portion and defining a free end, the second portions being and configured for engagement with a second bone segment; anda planar second segment that is elongated along a first direction comprising:
at least one compression opening including a first radius at a first end, a second radius at a second end that is larger than the first radius, side surfaces tangentially connecting the first and second radii, and a chamfer such that the compression opening is configured for receiving at least one male fixation member therethrough and into a first bone segment so that the fixation member acts against the chamfer to translate the plate and thereby apply a compressive force to secure the first bone segment with the second bone segment to form a corrective construct; andat least one substantially circular fixation aperture,wherein the first portions of the at least two members comprise linear portions that diverge from each other as they extend from the second segment to the second portions along the first direction, and are coplanar with the second segment, and wherein the first portions of the at least two members form a void that extends therebetween that is elongated along the first direction.
