Claims19
A bone fixation system, comprising:
- a bone fixation device comprising:
- a stabilizing body comprising:
- an obverse side;
- a reverse side opposite the obverse side;
- and
- a plurality of fastener openings extending through the obverse side and the reverse side;
- and
- a first leg integrally formed with the stabilizing body and extending from the reverse side of the stabilizing body to a first free end;
- and
- a second leg integrally formed with the stabilizing body and extending from the reverse side of the stabilizing body to a second free end;
- wherein the first free end is separated from the second free end by a first distance when bone fixation device is in an elastically deformed state;
- wherein the first free end is separated from the second free end by a second distance when the bone fixation device is in a relaxed state, the first distance being different than the second distance such that the bone fixation device provides a force at the first and second free ends when the bone fixation devices is in the elastically deformed state;
- wherein a longitudinal axis of the first leg and a longitudinal axis of the second leg are configured to converge when the bone fixation device is in the relaxed state;
- and
- wherein at least a portion of the stabilizing body between the first leg and the second leg is configured to deform when the bone fixation device transitions from the elastically deformed state to the relaxed state;
- and
- a plurality of fasteners configured to be positioned within the one or more fasteners openings of the stabilizing body and to extend through the stabilizing body.
