The present disclosure relates to a shoulder prosthesis comprising a glenoidal component having a glenoidal articulation surface and a humeral component having a humeral articulation surface, and a separate mobile glenohumeral bearing component comprising a glenoidal bearing surface and a humeral bearing surface arranged on opposite sides of the glenohumeral bearing component. The glenoidal bearing surface contacts in an implanted state the glenoidal articulation surface and/or the humeral bearing surface contacts in an implanted state the humeral articulation surface. At least one of the glenoidal and humeral bearing surfaces is concave. The glenohumeral bearing component is disposed in an implanted state between the glenoidal component and the humeral component. Both the glenoidal and humeral articulation surfaces are convex.

A modular reverse shoulder orthopaedic implant includes a humeral stem component and a separable fracture epiphysis component having a number of suture holes formed therein. The fracture epiphysis component is configured to receive a number of sutures for surgically repairing a proximal humeral fracture.

Orthopaedic Implants Having Self-Lubricated Articulating Surfaces Designed to Reduce Wear, Corrosion, and Ion Leaching

An orthopaedic implant can replace a joint in a patient. The orthopaedic implant includes a first component having a first component surface and a second component having a second component surface. The first component surface and the second component surface mate at an interface. The first component surface includes a metal substrate, a nanotextured surface, a ceramic coating, and a transition zone. The nanotextured surface is disposed directly upon the metal substrate and has surface features in a size of 10.sup.−9 meters. The ceramic coating conforms to the nanotextured surface and includes a plurality of bio-active sites configured to attract and retain calcium and phosphorous cations. The transition zone is disposed between the metal substrate and the ceramic coating. The transition zone includes a concentration gradient transitioning from the metal substrate to the ceramic coating and there is no distinct interface between the metal substrate and the ceramic coating.

GUIDES FOR FRACTURE SYSTEM
20170258607 · 2017-09-14 ·

A prosthetic shoulder implant system includes a prosthetic humeral implant and a version device. The humeral implant includes a catch member aperture and a first locking pin aperture. The version device includes a rotatable member with a body and a flexure member, and a plate with a catch member and a projection contacting the flexure member. A first locking pin extends from the version device and is adapted to mate with the first locking pin aperture. In an unlocked condition of the system, the rotatable member has a first rotated position in which the flexure member is in an uncompressed state and the plate is in a first position, and in a locked condition of the system, the rotatable member has a second rotated position in which the flexure member is in a compressed state and the plate is in a second position proximal of the first position.

System and method for fracture replacement of comminuted bone fractures or portions thereof adjacent bone joints

The system and method serves in facilitating replacement of comminuted bone fractures or portions thereof adjacent bone joints. The system and method employs a prosthesis to replace at least a portion of the comminuted bone fractures. The prosthesis serves in reproducing the articular surface of the portion or portions of the comminuted bone fractures that are replaced. In doing so, the prosthesis serves in restoring joint viability and corresponding articulation thereof.

TRIAL NECK PIECE FOR A JOINT ENDOPROSTHESIS

A trial neck piece for a joint endoprosthesis is designed for temporary arrangement on a separate shaft body (60) that is insertable into a tubular bone (9). It comprises a fastening region (12) which can be plugged temporarily onto a head part (61) of the shaft body (60) by means of a plug connection (l l), and a neck region (IO) for receiving a joint element (19) of the joint endoprosthesis. The trial neck piece (I) is designed as a separate, plug-on attachment piece which, with its fastening region (12), can be plugged with form-fit engagement onto the head part (61) and locked. A latching device (2) is provided which comprises a plurality of latching stages for different height stages of the trial neck piece (I). The invention thus makes available an easily attachable trial neck piece which can be arranged in a defined manner in different height positions in order, on the one hand, to obtain a secure and defined arrangement and, on the other hand, to permit the setting of different heights. The invention further relates to an arrangement with a trial neck piece and with an excavating tool, in particular a reamer, and to an instrument set comprising a trial neck piece and an insertion instrument.

SHOULDER PROSTHESIS COMPONENTS AND ASSEMBLIES

An inserter includes a first end, a second end, and a body extending between the first end and the second end. A first impacting surface is disposed at the first end, and a second impacting surface is disposed adjacent to the second end. An interface disposed at the second end and is configured to engage an implant. The first impacting surface is configured to direct a first impacting force along the body of the inserter in a first direction, and the second impacting surface is configured to direct a second impacting force along the body in a second direction that is different from the first direction. Methods of use also are disclosed.

SHOULDER PROSTHESIS COMPONENTS AND ASSEMBLIES

Various embodiments disclosed herein relate to stemmed and stemless humeral anchors for use in shoulder arthroplasty procedures. For example, the humeral anchor can include a first end, a second end, and an interior surface extending between the first end and the second end. The interior surface can be disposed about a recess disposed between the first end and the second end. The recess can be configured to secure a coupling of a shoulder articular body directly to the interior surface.
