A bone screw insertion device, comprises an outer sleeve extending from a proximal end to a distal end and including a channel extending therethrough and a driving member extending longitudinally through the channel of the outer sleeve from a proximal end to a distal end configured to engage a driving recess of a bone screw, the outer sleeve movable relative to the driving member between a first position in which the distal end of the outer sleeve extends over and covers a proximal portion of a bone screw engaged with the driving member, to a second position in which the distal end of the outer sleeve is longitudinally aligned with a proximal end of a bone screw engaged with the driving member.

Self-retaining screw and screwdriver

A screwdriver assembly includes a screwdriver shaft and an insert. The screwdriver shaft extends longitudinally from a proximal end to a distal end and having a longitudinal channel extending therethrough. The insert has a longitudinal shaft received within the longitudinal channel and a distal end extending distally relative to the distal end of the screwdriver shaft. The insert shaft is rotatable relative to the screwdriver shaft. The distal end of the insert is sized and shaped to engage a head of a screw. The distal end of the insert is disengaged from the screw head by rotating the insert relative to the screwdriver shaft.

Self-retaining screwdriver with engaging tip feature

In one example, a system has an insertion handle that can be coupled to an intramedullary nail and includes a first coupler that defines one of a recess and a projection, and one of a latch and an abutment surface. The system has an aiming guide that includes a guide body that defines at least one alignment aperture therethrough. The aiming guide includes a second coupler that can couple the guide body to the first coupler such that the at least one alignment aperture is positioned to guide an instrument towards at least one bone-anchor fixation hole of the intramedullary nail. The second coupler defines another of the recess and the projection, and another of the latch and the abutment surface. The first and second couplers can couple to one another by receiving the projection in the recess and by engaging the latch with the abutment surface.

System and method of coupling an alignment guide to an intramedullary nail insertion handle

In one embodiment, a strike instrument that couples to an insertion handle of an intramedullary nail has a shaft that extends along a shaft axis, and an abutment that extends outward relative to the shaft. The abutment is rotationally fixed to the shaft such that the shaft can rotate the abutment between a first orientation, where the abutment can be removed or inserted into the insertion handle, and a second orientation, where the abutment forms an interference with the insertion handle that prevents the abutment from being removed from the handle. The strike instrument includes a strike surface that can transfer an impaction force to the insertion handle, and a lock that engages the insertion handle so as to prevent the abutment from rotating from the second orientation to the first orientation after the abutment is rotated within the insertion handle from the first orientation to the second orientation.

Strike instrument for intramedullary nail

A system for treating a bone fracture includes an intramedullary nail sized and shaped to be inserted through a medullary canal of a bone to extend across a fracture site of the bone, the intramedullary device extending from a first end to a second end and including a plurality of openings extending laterally therethrough, the openings sized and shaped to receive bone fixation elements therethrough, and an insertion device including a base portion and a handle portion extending therefrom, the base portion integrally formed with the intramedullary nail and connected thereto via a plurality of connection points which, when a force is exerted thereon, break to disconnect the insertion device from the intramedullary nail, the base portion including a plurality of guide channels extending therethrough, each of the guide channels being aligned with a corresponding one of the openings of the intramedullary nail.
