Surgical positioners may include platforms, surgical item positioners and/or surgical references as well as methods for using stabilizer platforms, surgical item positioners and/or surgical references. Stabilizer platforms may include low profile platforms rigidly mounted to portions of an individual's anatomy. Various items may be secured and/or stabilized by the stabilizer platform, including support platforms as well as surgical references. Support platforms may stabilize and assist surgeons in using, navigating, aligning and positioning surgical items. Surgical references may include modular fiducial systems that may be secured to stabilizer platforms, support platforms, surgical items and/or directly to portions of an individual's anatomy.

Surgical positioners

Embodiments of the present invention include products and methods for reducing fractures with the aid of image guidance. In one embodiment, products and methods are directed to reduction for the placement of an intramedullary nail.

Image-guided fracture reduction

An apparatus for guiding the resection of the head of a humerus is provided. The apparatus includes a base, a cut block, and a stylus. The guide is used in connection with a reamer or other tool that is inserted into the intramedullary mayal of the humerus with the shank of the reamer extending superiorally above the head of the humerus to establish the axis of the humerus. The base is in rotatable connection with the reamer. The cut block is removably attached to the guide and has a component for receiving a saw blade. The stylus attaches to the cut block, preferably by engaging the component for receiving the saw blade, and extends around the articular margin of the humeral head to aid in setting height and version.

Humeral head resection guide

A series of humeral stems, each stem including an axial bore and longitudinal slots along the distal end to allow for distal compression. The compression force necessary to compress the distal diameter of each stem varies by stem diameter. Thus, as the stem diameter increases through the series, the compression force decreases.

Humeral stem with distal tri-slot

A modular radial head system including a modular implant for replacing the head of the proximal end of a radius and for articulating with the capitellum of a humerus. The modular implant includes a modular head and an modular stem. The system further includes a modular radial head locking instrument for locking the modular head and the modular stem of the modular implant to one another. The locking instrument includes a first jaw, a second jaw, and a control mechanism for urging the first and second jaws together to provide offset axial compression of the modular head and the modular stem of the modular implant.

Radial head implant system including modular implant and modular radial head locking instrument

A system including modular radial head implants, sizers for trial reduction of the joint, and instrumentation for preparing the radial head, implanting the sizers, assembling the implants.

Modular implant for replacing end of radius and having drainage passage for trapped fluid

An intramedullary nail for use in combination with a proximal bone screw. The nail includes an elongated body having a proximal end and a distal end with a central axis extending between the proximal end and the distal end. The proximal end of the body has a transverse slot therethrough, the transverse slot therethrough with contour for allowing the proximal bone screw to be inserted through the transverse slot and through the proximal end of the body with the longitudinal axis of the proximal bone screw located at an angle to the central axis of the body of the nail within a range between an acute angle on either side of a plane extending transverse to the central axis of the body of the nail.

Modular intramedullary fixation system and insertion instrumentation

A femoral neck anteversion guide for use with a femur having a prepared intramedullary canal. The guide includes a radiolucent stem having a distal end for inserting into the prepared intramedullary canal; and a radiopaque angle locator wire embedded within the stem at a known angle for allowing the femoral neck angle and femoral neck anteversion to be determined.
