Abstract: Devices and methods for bending or cutting implants are disclosed herein. In some embodiments, an instrument can include a rotatable drive shaft that urges first and second portions of a modular bending or cutting template toward one another to bend or cut an implant disposed between the template portions. A linkage assembly can be included to provide a mechanical advantage in urging the template portions toward one another. In some embodiments, an instrument can include a rotatable drive shaft that, depending on direction of rotation, pushes or pulls a first modular template portion with respect to a second modular template portion to bend an implant disposed between the template portions in one direction or another direction. In some embodiments, an instrument can include a worm drive that rotates a cutting wheel with respect to a cutting plate to cut an implant inserted through openings formed in the cutting wheel and the cutting plate.

Abstract: An intramedullary (IM) nail insertion assembly includes an IM nail extending longitudinally from a proximal end to a distal end. A proximal portion of the IM nail has an internal threading. The IM nail insertion assembly also includes a connecting screw extending longitudinally from a proximal end to a distal end. A distal portion of the connecting screw has an external threading for engaging the internal threading of the IM nail. One of the proximal portion of the IM nail and the distal portion of the connecting screw has a feature to resist a disengagement of the proximal portion from the distal portion.

Abstract: 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 bead by rotating the insert relative to the screwdriver shaft.

Abstract: A nut for treating a bone includes a head and a body extending longitudinally from the head to a free end and including a channel extending longitudinally thereinto from the free end, the channel configured to engage an end of a bone screw, and an exterior threading extending about the body from an exterior surface thereof along an entire length thereof, an outer contour of the exterior threading defined via radially outermost edges of the exterior threading, a first portion of the outer contour adjacent the head portion having a smaller diameter than a second portion of the outer contour extending from the first portion to the free end of the body.

Abstract: A device includes an outer sleeve of flexible material forming an outer conduit extending longitudinally therethrough for the insertion of a bone treatment device (“BTD”) to target sites within a living body. A distal opening of the outer conduit is open so that, when the outer sleeve is in a desired position within the body, BTD is inserted through the outer conduit exits the outer sleeve adjacent to a target portion of a bone. The device also includes an inner sleeve received within the outer sleeve and defining an inner conduit within the outer conduit to form a protective covering. The inner sleeve is split longitudinally. Portions of the inner sleeve on opposite sides of the split are coupled to one another so that a diameter of the inner conduit is adjustable in response to forces exerted thereon by one of BTD and tissues surrounding the outer sleeve.
