A retrograde intramedullary nail for insertion in the medullary canal of a femur includes a body that is elongate and defines a leading end and a trailing end spaced from each other at a length sufficient to extend from an intercondylar region at least to a subtrochanteric region of the femur. The body further defines a leading portion that extends to the leading end. The leading portion defines at least one locking hole configured to receive a fixation member. The at least one locking hole defines a central hole axis that is oriented to extend through the neck and head of the femur.

Bone plate

A bone plate comprises a plate body and at least one tab. The plate body defines an inner body surface configured to face an underlying bone, an outer body surface opposite the inner body surface, and an outer side surface that extends between the inner body surface and the outer body surface. The outer side surface defines an outer perimeter of the plate body. The at least one tab includes a head and an arm that extends from the plate body to the head. The tab defines a tab aperture that extends through the head and is configured to receive a bone anchor. The bone anchor can be coupled with a screw hole in the nail. The arm is configured to deflect with respect to the plate body so as to move the head between a pre-fixation position and a fixation position spaced from the pre-fixation position.

An intervertebral implant for insertion into an intervertebral disc space between adjacent vertebral bodies or between two bone portions. The implant includes a spacer portion, a plate portion operatively coupled to the spacer portion and one or more blades for securing the implant to the adjacent vertebral bodies. The blades preferably include superior and inferior cylindrical pins for engaging the adjacent vertebral bodies. The implant may be configured to be inserted via a direct lateral trans-psoas approach. Alternatively, the implant may be configured for insertion via an anterior approach.

In one embodiment, a targeting guide is formed by aligning an axis of a cutting instrument with a bone-anchor fixation hole of an intramedullary nail. The cutting instrument is inserted through the bone-anchor fixation hole such that the cutting instrument is in contact with a guide body of a targeting guide, where the targeting guide is supported relative to the intramedullary nail such that the guide body is spaced outwardly from at least a portion of the intramedullary nail along a radial direction. The cutting instrument is then driven through the guide body so as to form an alignment aperture in the targeting guide. The alignment aperture has a central axis that is aligned with the bone-anchor fixation hole.

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.

A guide sleeve for use in anchoring a fixation member to an intramedullary nail and to bone includes a sleeve body that is elongate along a central axis and has an internal surface that defines a bore extending along the central axis to a distal end of the sleeve body. The sleeve body also defines a plurality of guide channels that are each recessed radially outwardly from the internal surface and each include a helical proximal portion and a linear distal portion that extends from the helical proximal portion toward the distal end. The linear distal portion is parallel with the central axis. The guide channels are configured to receive respective complimentary followers of an instrument for driving the fixation member through the bore and subsequently through the intramedullary nail and into the bone.

In one embodiment, an intramedullary nail insertion system has a handle, a coupler, and a securement member. The handle has a body that includes a distal body end, and a proximal body end that is spaced from the distal body end along a proximal direction. Further, the handle defines an aperture that extends from the distal body end to the proximal body end. The coupler includes a distal coupler end having a first fastener that fastens to an intramedullary nail, and includes a proximal coupler end having a second fastener sized to be received through the distal body end in the proximal direction into the aperture of the handle. The securement member has a third fastener that fastens to the second fastener of the coupler so as to capture the handle body between the securement member and the intramedullary nail. The system can be assembled using a two-handed operation.

An expandable interbody spacer () is provided that includes a pair of oppositely facing endplate components () and an interior component that includes one or more vertically extending stacks of arranged C-clip members () radially surrounding one or more bosses () protruding interiorly from one of the endplates, wherein the size and configuration of the bosses and the C-clip members are designed to allow the incremental expansion of expandable interbody spacer.
