Bone fracture repair kit, components, and methods of use of same

A coupler that releasably attaches an intramedullary implant to a targeting guide used to secure the intramedullary implant to one or more fragments of a fractured bone via fasteners inserted through corresponding holes of the intramedullary implant and the targeting guide that are aligned when the intramedullary implant is attached to the targeting guide by the coupler, the coupler comprising:

• a sleeve comprising:
• a sleeve proximal end, a sleeve distal end, a sleeve body extending therebetween, and defining a sleeve lumen extending therethrough along a first longitudinal axis,
• wherein the sleeve comprises an engagement portion defining a recess that extends into the sleeve body radially toward the first longitudinal axis along a length of the engagement portion;
• and
• a fastener comprising:
• a fastener proximal end, a fastener distal end, a fastener body extending therebetween, and defining a fastener lumen extending therethrough along a second longitudinal axis, wherein the fastener distal end comprises a threaded surface, and
• herein a cross-sectional shape of a distal portion of the fastener body fits within the sleeve lumen.

A method of assembling a bone fracture repair kit, the method comprising:

• assembling a coupler comprising a fastener and a sleeve, wherein the sleeve has sleeve proximal end, a sleeve distal end, a sleeve body extending therebetween, and a sleeve lumen extending therethrough along a first longitudinal axis, and wherein the fastener has a fastener proximal end, a fastener distal end, a fastener body extending therebetween, and defining a fastener lumen extending therethrough along a second longitudinal axis;
• inserting the fastener distal end into and through the sleeve lumen;
• connecting the fastener distal end to an intramedullary implant while a portion of the fastener is within the sleeve lumen;
• abutting an actuator of a targeting guide with an engagement portion of the sleeve to secure a position of the sleeve relative to the targeting guide;
• disengaging the actuator from the engagement portion of the sleeve;
• and
• moving the targeting guide relative to the sleeve, fastener, and intramedullary implant while the actuator is disengaged from the engagement portion.

A targeting guide kit comprising:

• a first body defining a first set of one or more fastener guide holes extending therethrough;
• a second body defining a second set of one or more fastener guide holes extending therethrough;
• and
• an extension defining a third set of one or more fastener guide holes extending therethrough,
• wherein the extension is attachable to the first body in a first orientation, releasable from the first body, and attachable to the second body in a second orientation that is different from the first orientation.
