The elbow prosthesis includes an ulnar component that has a bearing end and a stem. The stem attached to the bearing end and extends in a distal direction from it. The elbow prosthesis also has a humeral component that includes a holder end and a stem with the stem extending in a proximal direction from the holder end. The prosthesis further includes at least one bearing member that is connected to the holder end with the bearing end being attached within the holder end to allow for rotation and articulation against the at least one bearing member. The bearing end and holder are attached to each other by a coupling mechanism that includes an opening positioned on the posterior aspect of the holder end and a mating surface on the bearing body. A method of using the elbow prosthesis and a total elbow prosthesis kit are also disclosed.

An elbow prosthesis constructed in accordance to one example of the present teachings can include a capitellar implant having an articulating head and a stem. The articulating head can have a first articulating surface positioned generally between a lateral side and a medial side. A passage can extend through the articulating head from the lateral side to the medial side. The articulating head can define a counterbore formed at the lateral side and that is concentric with the passage. According to other features, the elbow prosthesis can include a coronoid implant that has a body and a stem. The body can have a superior articulating surface that includes a central ridge and an anterior buttress. The central ridge can be configured to accommodate articulation with a trochlea in an implanted position.

A method of stabilizing a patient's ulnohumeral joint including the steps of: obtaining a stabilizing assembly having a mounting portion and a buttressing portion; and implanting the stabilizing assembly into an operative position wherein the mounting portion of the stabilizing assembly is anchored at a proximal region of the patient's ulna and the buttressing portion is situated to abut the patient's humerus so as to limit subluxation at the ulnohumeral joint while allowing movement between the patient's ulna and humerus at the patient's ulnohumeral joint.

The present invention regards an elbow spacer device, including: at least one ulnar section, including a stem portion extending along a substantially longitudinal axis (x-x) between a proximal end and a distal end; at least one humeral section, including a stem portion extending along a substantially longitudinal axis (y-y) between a proximal end and a distal end, the distal end of the humeral section delimiting an engagement seat with the proximal end of the ulnar section; articulation means between the distal end of the humeral section and the proximal end of the ulnar section, positionable along an axis (z-z) that is orthogonal to the substantially longitudinal axis (y-y) of the humeral section. The proximal end of the ulnar section is engageable in the housing seat.

A method and apparatus for replacing a selected portion of the anatomy is described. In particular, a prosthesis can be provided to replace a portion of an articulating joint, such as an elbow. The apparatus can be modular for various reasons and each of the modular portions can include a different dimension to achieve a selected result. For example, the prosthesis can achieve a different size condylar replacement, a selected offset, a selected articulation, or combinations thereof.

Apparatus and methods for total elbow replacement are provided to allow a surgeon to intraoperatively select a linked or unlinked constraint by utilizing a connection located on the body of the ulnar and/or humeral stem. Additional modularity also allows the selection of a cemented or cementless stem as described herein. The modularity and adjustability provides a number of advantages.

Methods and devices are disclosed for joint (e.g., shoulder) arthroplasty, including for reverse joint arthroplasty. In one aspect, there is provided a trial device for determining inclination, offset, and/or version of a prosthetic tray with respect to a prosthetic stem or stemless implant. In another aspect, there is provided a joint (e.g., shoulder) prosthesis, which allows for variable offset, inclination or version or any combination thereof. In another aspect, there is provided a method for setting an offset or inclination angle or a version angle or any combination thereof of a prosthetic tray with respect to a stem or stemless device implanted or to be implanted in a bone of a joint (e.g., shoulder) by matching the corresponding offset or version or inclination or any combination thereof to a trial device.

An elbow prosthesis includes a stem structure and an articulating component. The stem structure is operable to be positioned in a bone of a joint and includes a stem portion and a C-shaped body portion. The stem portion is operable to be positioned in the bone. The C-shaped body portion includes a first articulating surface bound by a medial wall and a lateral wall. The medial and lateral walls are separated by a first distance. The articulating component includes a second articulating surface positioned between a medial side surface and a lateral side surface. The medial and lateral side surfaces are separated by a second distance that is less than the first distance. The second articulating surface is configured to slidably communicate in a medial/lateral direction along the first articulating surface of the C-shaped body portion.
