Bone fixation system including K-wire compression

摘要

A bone fixation system includes a bone plate, bone anchors, temporary fixation members, and forceps. The temporary fixation members are configured to be inserted through apertures in the bone plate and into underlying bone segments that are separated by a bone gap. The forceps are configured to apply a force to the temporary fixation members that causes at least one of the underlying bone segments to translate with respect to the other bone segment, thereby reducing or distracting the bone segments without interfering with final fixation by screws of bone segments.

主权项

1. A forceps configured to apply a biasing force to a pair of temporary fixation members, each temporary fixation member having a distal portion and an engagement member disposed proximal of the distal portion, the engagement member defining a dimension greater than that of the distal portion, the forceps comprising:
a pair of arms, each arm having:
a proximal end and an opposed distal end;an arm engagement member defining a first pocket that extends into the distal end such that the first pocket defines a channel that extends through the distal end along a vertical direction, the first pocket further defining an engagement surface that defines a horizontal radius of curvature swept along a horizontal direction and a vertical radius of curvature swept along the vertical direction, the horizontal radius of curvature being equal to or greater than the vertical radius of curvature; wherein relative movement of the arms causes the distal ends to correspondingly move, such that each first pocket at least partially receives a respective one of the temporary fixation members and each engagement surface applies a biasing force against the engagement member of respective one of the temporary fixation members.
