A bone reamer includes a shaft having a first and a second end. The second end is configured to connect to a rotating power source. A head of the reamer includes a rear face connected to the first end of the shaft, a cutting face on an opposing side of the head relative to the rear face, and a perimeter portion having an inner perimeter diameter and an outer perimeter diameter. The outer perimeter diameter defines outer boundaries of the rear face and the cutting face. A blade member of the reamer is disposed upon the cutting face and extends at least across the inner perimeter diameter of the perimeter portion. A center drill bit is disposed on the cutting face. The drill bit and cutting blade are concentric about a center axis of the reamer.

Bone reamer and methods of use

Implants, device, systems and methods for replacing an articulation surface in a joint, for example, a reverse glenoid implant with a baseplate, a central screw, a peripheral screw, a modular taper, and a post. Methods for implanting the glenoid implant are also disclosed.

Implants, systems and methods of using the same

Implants, device, systems and methods for replacing an articulation surface in a joint, for example, a glenoid implant with an articular surface and an opposing bone contacting surface having a ring and post extending therefrom that respectively mechanically connect with cortical bone and cancellous bone of a glenoid. Methods for implanting the glenoid implant are also disclosed.

An elbow arthroplasty system having a ball and a socket. The ball is configured for coupling to at least one member of one of the following groups: (i) a humerus, and (ii) a radius, an ulna, or both of the radius and the ulna. The socket is configured for coupling to at least one member of the other of the following groups: (i) the humerus, and (ii) the radius, the ulna, or both of the radius and the ulna. The socket defines a cavity that is configured to receive at least a portion of the ball. The ball may be a spheroid, an ellipsoid, a sphere, or a portion of one of the foregoing with a convex surface. The socket may be configured with a concave surface that is spheroidal, ellipsoidal, or spherical and designed to mate with the ball. An elbow arthroplasty method using a ball and a socket.

System, apparatus, and method for elbow arthroplasty

A single-use handle is configured to attach to a working shaft that can support a sounder for measuring the medullary canal of a proximal radius, and a planarizer that is configured to planarize a proximal edge of the proximal radius after the proximal radius has been resected. The handle can further include a plurality of sizing cavities that are configured to receive the resected bone so as to determine the size of the resected bone. The handle can further include an ejector that is configured to decouple the planarizer from the working shaft.

Surgical instrument handle with implant sizing feature and method of using

Implants, device, systems and methods for replacing an articulation surface in a joint, for example, shoulder prostheses with stemless humeral components or stemmed humeral components. Methods for using the shoulder prostheses with stemless humeral components or stemmed humeral components are also disclosed.

An orthopedic implant apparatus, said apparatus comprising: a body, said body having a generally cylindrical shape and comprising a first material, a flat bottom surface, a concave upper surface disposed opposite said bottom surface, and a longitudinal axis disposed through the center of said body; a cylindrical bore, said bore disposed along said longitudinal axis through said top surface of said body; cylindrical plug, said plug comprising a second material and disposed within said bore of said body; and at least one stem, said at least one stem connected to said bottom surface of said body.

Radial head orthopedic implant apparatus and method of using same

An orthopedic trial implant having a plurality of bearing component augments of differing heights, where each augment releasably, slidably connected to the trial implant.

Trial radial head implant

An orthopedic implant apparatus, said apparatus comprising: a body, said body having a generally cylindrical shape and comprising a first material, a flat bottom surface, a concave upper surface disposed opposite said bottom surface, and a longitudinal axis disposed through the center of said body; a cylindrical bore, said bore disposed along said longitudinal axis through said top surface of said body; a cylindrical plug, said plug comprising a second material and disposed within said bore of said body; and at least one stem, said at least one stem connected to said bottom surface of said body.

A trial orthopedic implant having a plurality of bearing component augments of differing heights, where each augment releasably, slidably connected to the trial implant.

A single-use handle is disclosed for releasably engaging an orthopedic device. The handle includes an elongate body that has a first portion that, in turn, defines a connection end adapted for connection to an upper end portion of a broach. The handle includes a second end portion adapted to be griped by a user. The handle further includes a cylindrical bore at the connection end. The bore is configured to receive a corresponding male portion of a surgical instrument. The handle further includes a button that is adapted to releasably connect the instrument in the bore. The handle further includes a plurality of sizing cavities that have a predetermined size and shape that corresponds to the size and shape of an orthopedic implant. The handle is of a biocompatible, disposable material.
