An intramedullary nail includes one or more nail openings extending therethrough. The intramedullary nail is implantable within a medullary canal of the bone. A bone plate is configured to engage an outer surface of the bone. The bone plate includes one or more plate openings extending therethrough. The plate openings are spaced about the bone plate such that the bone plate is positionable to axially align the plate openings with the nail openings when the intramedullary nail is implanted within the medullary canal of the bone. An aiming guide includes one or more targeting openings. The targeting openings are spaced about the aiming guide such that the aiming guide is positionable to axially align the targeting openings with the plate openings and the nail openings for extending one or more stabilizing fasteners therethrough when the intramedullary nail is implanted within the medullary canal of the bone.

An orthopedic drill bit includes a cutting head formed to include diametrically opposed cutting lips leading to a central point and away to a radiused periphery to center said bit. The drill includes flutes extending from a cutting end, said flutes having a dulled periphery to prevent out of round holes. The flute design increases in width progressively from the tip up the shank, to maintain an adequate and unrestricted space for chips to easily move upward, preventing the chips from being compressed into a smaller opening while maintaining the tapered depth of the flutes for strength.

A method of repairing a fractured humerus may include implanting a prosthetic humeral stem into a humeral canal of the fractured humerus. First and second tuberosities of the fractured humerus may be robotically machined to include first and second implant-facing surfaces that are substantially negatives of first and second surface portions of the proximal end of the prosthetic humeral stem. The first and second tuberosities may be machined so that the first and second tuberosities have first and second interlocking surfaces shaped to interlock with each other. During implantation, the first and second implant-facing surfaces are in contact with the first and second surface portions of the proximal end of the prosthetic humeral stem, and the first interlocking surface interlocks with the second interlocking surface.

Disclosed are bone screw drill targeting guides and methods for using such targeting guides that are useful in surgical procedures for correcting hallux valgus deformity.

Provided herein are compositions and methods for treating bone fractures. In particular, provided herein are systems comprising carbon fiber sleeves and biocompatible polymers and the use of such systems in treating or preventing bone fractures.

In one aspect, an implant configured to attach a first bone section to a second bone section comprises an intramedullary portion and an extramedullary portion. The intramedullary portion is configured for insertion into the first bone section. The ex-tramedullary portion is configured to abut a surface of the second bone section and includes a first fastener aperture configured to eceive a bone fastener inserted in the second bone section. The intramedullary portion and the extramedullary portion are coupled such that the extramedullary portion is rotatable with respect to the intramedullary portion.

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 TM 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.

A surgical fastener includes a cannulated collapsible fastening body having a trailing end and a leading end and defining a passage extending from the trailing end to the leading end, and a pin having a non-threaded shaft at least partially disposed within the passage and an enlarged tip. A method of using the surgical fastener includes engaging an end of a driver with a recess in a head of the surgical fastener, including inserting an extension at the end of the driver into the passage, and inserting the fastener into a bore in a bone during which the extension of the driver abuts a trailing end of the shaft of the pin to prevent the pin from moving in a direction from the leading end to the trailing end relative to the fastening body.

A surgical instrument assembly configured to display a representation of the surgical instrument relative to a trajectory (e.g., a desired trajectory for drilling into an implant) based image data from an image sensor (e.g., a camera). For example, the surgical instrument assembly may be configured to determine a desired trajectory (e.g., a central axis of a distal hole of an intramedullary nail) based on X-ray image data representing at least one fiducial marker (e.g., an array of ArUco markers) and representing an anatomical structure and/or an implant. The surgical instrument assembly may in real time display a representation of the orientation and/or position of the surgical instrument (e.g., the orientation and position of a drill bit of the surgical instrument) in relation to the desired trajectory based on image sensor data that is generated based on an orientation of the at least one fiducial marker detected by an image sensor.
