Abstract
System, including methods, apparatus, and kits, for bone fixation using a fixation device including a mounting portion and a fastener that attaches to the mounting portion. In some embodiments, the fixation device may include first and second mounting portions configured to be disposed across a bone from each other and secured with a fastener that extends from one of the mounting portions, through the bone, and to the other mounting portion. The system also may include a tool to facilitate installation of the fixation device.
Claims20
An instrument for installing a bone fixation device, the instrument comprising:
- a frame member formed to include a distal jaw and a drill stop including a notch, wherein the distal jaw and the drill stop extend from a body portion of the frame member in a same direction, wherein the drill stop is not part of the distal jaw;
- a carriage formed to include a proximal jaw, the carriage slidably coupled to the frame member so as to form a receiver region between the distal jaw and the proximal jaw;
- and
- a drive screw engaged with the frame member and/or the carriage such that rotation of the drive screw causes relative movement between the frame member and the carriage, wherein relative movement between the carriage and the frame member adjusts a distance between the distal jaw and the proximal jaw.
An instrument for installing a bone fixation device, the instrument comprising:
- a frame member formed to include a distal jaw;
- a carriage formed to include a proximal jaw, the carriage slidably coupled to the frame member so as to form a receiver region between the distal jaw and the proximal jaw, wherein the frame member has a greater length than the carriage, and wherein each the distal jaw and the proximal jaw includes one or more projections extending into the receiver region;
- a drive screw engaged with the frame member and/or the carriage such that rotation of the drive screw causes relative movement between the frame member and the carriage along an axis, the axis parallel to a longitudinal axis of a body portion of the frame member, wherein relative movement between the carriage and the frame member adjusts a distance between the distal jaw and the proximal jaw along the axis;
- and
- a gauge configured to display an indication corresponding to the distance between the proximal and distal jaws.
An instrument for installing a bone fixation device, the instrument comprising:
- a frame member formed to include a distal jaw and a drill stop including a notch, wherein the distal jaw and the drill stop extend from a body portion of the frame member in a same direction, the distal jaw is at a distal end of the frame member and the drill stop is at a proximal end of the frame member;
- a carriage formed to include a proximal jaw, the carriage slidably coupled to the frame member so as to form a receiver region between the distal jaw and the proximal jaw;
- and
- a drive screw engaged with the frame member and/or the carriage such that rotation of the drive screw causes relative movement between the frame member and the carriage, wherein relative movement between the carriage and the frame member adjusts a distance between the distal jaw and the proximal jaw.
