An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.

Tools for cutting bone, specifically cutting a hemispherical cavity in bone. Preferably, tools including an adaptor device configured to provide independent control of the cutting orientation.

The present disclosure relates to a system and method for repairing an articular surface. A guide pin may be secured to an articular surface of a glenoid, wherein the guide pin defines a working axis and the working axis is positioned at an angle α relative to the articular surface, wherein angle α is less than or equal to 90 degrees. An excision device may be advanced over the guide pin, wherein the excision device includes a cannulated shaft and at least one cutter, wherein the at least one cutter is generally aligned in a single plane. A generally hemi-spherical excision site may be formed with the excision device within the articular surface of the glenoid.

Milling device for prosthetic surgery comprising a milling tool rotating about a milling axis, and a handling body. The handling body is provided with a drive rotating rod which develops along a longitudinal axis of linear rotation and is connected to the milling tool in order to make the milling tool rotate about the milling axis.

A drill guide assembly for drilling a tunnel having a fixed, non-zero radius of curvature, where the drill guide assembly includes a housing and a sleeve, or cutting tube, configured to reciprocate within the distal portion where the sleeve, or cutting tube, is configured to receive a bone cutting instrument.

A kit for use in performing joint arthroplasty on a head of a long bone is disclosed. The kit includes: a first implant including a first implant articulating surface and an opposed first implant mounting surface having a first implant location feature; and an instrument for preparing a cavity in the head of the long bone. The instrument includes a body and a punch extending from the body. The punch includes a portion thereof having a shape similar to the first implant location surface of the implant. A method for providing joint arthroplasty is also disclosed.

A rotary cutting tool including an elongated housing having a proximal end and a distal end, the elongated housing extends circumferentially around a first axis. A drive shaft disposed within the elongated housing and extending between the proximal end and the distal end and rotatable about the first axis. A cutting bit housing coupled to the distal end of the elongated housing and rotatable relative to the drive shaft about an articulation axis between a non-articulated position and one or more articulated positions. A rotary cutting bit coupled to the cutting bit housing and the drive shaft and rotatable about the articulation axis with the cutting bit housing, the rotary cutting bit and drive shaft forming a constant velocity joint.

A modular reverse shoulder prosthesis according to embodiments of the present invention includes a stem having a proximal taper and a primary stem axis, the proximal taper extending from the stem about a metaphyseal axis, the metaphyseal axis at an angle with respect to the primary stem axis, a metaphysis having a proximal end, a distal end, a first aperture in the distal end configured to be placed over the proximal taper, and a second aperture in the proximal end having an insert axis that is eccentrically offset from the metaphyseal axis, the metaphysis configured for attachment to the stem at any rotational position of the metaphysis about the metaphyseal axis, and a reverse insert, the reverse insert having a proximal end and a distal end, wherein the proximal end comprises a concave cup formed about a cup axis and configured to receive a glenosphere, and wherein the distal end comprises a locking protrusion, wherein the locking protrusion has an outer surface with a cross-sectional shape that is rotationally symmetrical about the insert axis with respect to a corresponding inner surface of the second aperture, wherein the rotational symmetry has an order of six, seven, eight, nine, or ten.

A system for reaming a bone including a guiding wire configured to be attached to the bone; a tubular depth guide configured to cover at least a portion of the guiding wire, the tubular depth guide including a first end configured to abut the bone, and a second end opposite the first end; a reaming device including an elongate recess therein that extends between a reaming tool of the reaming device and an interior of the reaming device, wherein the elongate recess is configured to receive each of the guiding wire and depth guide therein, the elongate recess includes a reduced diameter section that defines a shoulder, and the shoulder is designed to abut the second end of the tubular depth guide to control a depth to which the bone is reamed.

A drill guide includes a working portion and a shaft, with a joint formed between the working portion and the shaft so that the shaft is movable relative to the working portion about the joint. The working portion includes at least one drill guide hole which receives a drill for making a hole in a bone. The joint isolates the working portion from unintentional movements of the shaft so that the working portion remains stable against a bone surface. The joint also enables the shaft to be used as a retractor or pry bar against surrounding anatomical structures if desired. The drill guide may be included in a system with an implant component and/or other surgical instruments.
