A drill guide handle configured to engage a variable angle drill guide, including: a handle grip; a first cannula extending from a proximal end of the drill guide handle to a distal end of the drill guide handle, wherein the first cannula is configured to provide a zero degree insertion angle for a drill bit; and a body including: a first tab and a second tab wherein the first and second tabs include a first and second tab protrusion, respectively, wherein each of the first tab and the second is configured to flex so that the first and second tab protrusions engage a horizontal groove on a variable angle drill guide; and a body protrusion on an inner surface of the body, wherein the body protrusion is configured to engage a vertical grove on the variable angle drill guide.

A modular system for treating a bone includes a main body including a channel extending therethrough. A distal end includes a driving feature sized and shaped to engage a corresponding driving structure of one of first and second bone screws. The system also includes an inner shaft sized and shaped to be inserted into the channel and including a distal end including a retaining feature for engaging a corresponding retaining structure extending within a recess at a proximal end of the first screw. Furthermore, the system includes an outer shaft extending longitudinally and including a channel extending therethrough. The channel of the outer shaft is sized and shaped to slidably receive the main body therein and including a retaining feature extending along a distal end thereof. The retaining feature of the outer shaft engages a retaining structure extending along an exterior surface of the second screw.

A driver for engaging an endcap of an intramedullary nail. The driver includes a handle extending along a longitudinal axis of the driver from a proximal end to a distal end. The handle having a handle channel extending longitudinally therethrough. The driver also includes a shaft extending through the handle channel from a proximal end to a distal end along the longitudinal axis. The shaft having a shaft channel extending longitudinally therethrough. The distal end of the shaft extends distally from the handle. The distal end of the shaft forms a driving element to be inserted into a head portion of the endcap. The driver further includes a retention pin slidably received in the shaft channel. The retention pin extends also extends along the longitudinal axis. The distal end of the retention pin is configured to reversibly lock the shaft to the head portion of the endcap.

An endcap for engaging a proximal end of an intramedullary nail. The endcap includes a body extending from a first end to a second end and configured to engage a channel of an intramedullary nail. The endcap also includes a head portion at the first end of the body. The head portion includes a recess sized and shaped to receive a driving element of a drive shaft. The recess includes elastic tabs extending radially toward a central axis of the recess to engage and retain a driving element received therein.

An implant insertion assembly including an insertion handle extending from a proximal end to a distal end, the distal end including a recessed portion, an outer wall of the recessed portion having a first shape about a perimeter thereof and including an engagement mechanism. The implant insertion assembly also includes an implant extending from a distal end to a proximal end including an opening configured to receive the recessed portion of the insertion handle, the opening having a second shape configured to mechanically interlock with the outer wall of the recessed portion when the recessed portion is inserted therein to transmit torque from the insertion handle to the implant, the proximal end including a receiving structure in a wall thereof, the receiving structure being positioned and oriented to receive the engagement mechanism to removably lock the insertion handle to the implant in the axial direction.
