An assembly includes a first portion including an anchor pivotally attached to a first end of the first portion, the anchor to be inserted into an intramedullary canal of a first bone fragment; a second portion pivotally attached to a second end of the first portion and including a first skin-interfacing portion; a second skin-interfacing portion to interface with and secure the assembly to skin adjacent to the first bone fragment; and an actuation mechanism attached between the first portion and the second portion that actuates pivoting of the second portion to the first portion; wherein a lateral force is generated between the first skin-interfacing portion against a second bone fragment, adjacent to the first bone fragment, and a holding force is provided by the anchor when the actuation mechanism is actuated, so the first portion pivots with respect to second portion, while the anchor is in the intramedullary canal.

Implants and instruments for providing an ideal trajectory for the insertion of instruments and screws during implantation of an interbody implant in a spinal surgery are disclosed.

An extracorporeal bone compressing link and apparatus and method using same. Active devices that incorporate the extracorporeal bone compressing link can transport and compress bone through external means by acting on conventional bone fasteners including but not limited pins or wires that penetrate through the skin and fixate into bone.

A pin removal tool includes a first arm member and a second arm member opposing the first arm member and connected to the first arm member at a pivot axis. The first and second arm members form a first interface therebetween at a first end of the tool configured to remove a headless pin and a second interface therebetween at a second end of the tool configured to remove a headed pin.

A universal wire driver attachment comprises a driveshaft forming a lumen extending along a longitudinal axis. The driveshaft forms a plurality of channels extending perpendicularly from the longitudinal axis. The attachment further comprises a plurality of primary jaws movably disposed at least partially within the channels. The primary jaws comprise a plurality of wire gripping surfaces facing the longitudinal axis and configured to grip the surgical wire. The primary jaws cooperate with the channels such that the primary jaws are constrained from moving in an axial direction along the longitudinal axis. The primary jaws are capable of moving outward from the longitudinal axis when the surgical wire is inserted between the primary jaws, and the primary jaws are capable of being urged inward toward the longitudinal axis by the securing mechanism to increase a grip force on the surgical wire.

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.

A bone fastener assembly instrument that can assemble a two-component bone fastener during surgery is provided. The bone fastener may be of a type that comprises a threaded bolt and nut for securing an implantable device to bone, such as a spinous process. A method for using the bone fastener assembly instrument is also provided.

A femur fixation system includes an intramedullary nail that includes a first bending stiffness and a bone plate that includes a second bending stiffness and a second torsional stiffness. In the femur fixation system either at least one of the second torsional stiffness compensates for the first torsional stiffness and the first torsional stiffness is insufficient to enable the intramedullary nail to stabilize the bone fracture independently of the bone plate or the first bending stiffness compensates for the second bending stiffness and the second bending stiffness is insufficient to enable the bone plate to stabilize the bone fracture independently of the intramedullary nail.

An instrumentation system (100) and an intramedullary femoral nail system (1) for antegrade or retrograde implantation with laterally inserted bone screws, the system comprising a nail stem (2) having a multi-featured proximal end (3), a distal end and a central conduit (22) configured to accommodate a fastener (4), wherein the multi-featured proximal end (3) comprises a plurality of holes (20) configured to accommodate at least two bone screws (50, 52), wherein the first bone screw (50) is at an angle that is horizontal relative to the central conduit (22) and is on a coronal plane, and the second bone screw (52) is at an angle of between 120° to 130° relative to the central conduit (22).

This disclosure describes exemplary screw and intramedullary devices that are better able to bring bone fragments into close proximity with each other, generate a compressive load, and maintain that compressive load for a prolonged period of time while healing occurs. The devices are made of a shape memory material.
