Abstract: The present disclosure is directed towards implants configured to compress a tendon in place relative to a bone, as well as associated systems, devices, instruments, and methods for performing tenotomy and tenodesis procedures utilizing the implants. The systems for compressing the bone include a sleeve having a first end, a second end, and a through-hole extending longitudinally through the sleeve from the first end to the second end, and a fixator having a sharp tip, the implant configured to be inserted through the through-hole. The implant includes a head, a stem extending from the head, and a cavity having a first opening in the head. The cavity extends through the head and into at least a portion of the stem, and a hard tip is connected to the stem.

Abstract: A reverse shoulder system can include, for example, a glenoid baseplate comprising a longitudinal axis, the glenoid baseplate further including a stem and a central channel within a sidewall of the stem. The stem can include a longitudinal axis. The longitudinal axis of the glenoid baseplate can be angled with respect to the longitudinal axis of the stem, wherein the longitudinal axis of the glenoid baseplate is not perpendicular with respect to the longitudinal axis of the stem. Other components including a glenosphere, tools, and methods of use are also disclosed.

Abstract: In some embodiments, disclosed is a glenohumeral implant with improved joint mobility. The implant can include a backing component; a neutral non-inclined bearing component on a concave side of the backing component, the bearing component made from a different material than the backing component and configured to touch a glenosphere having a center of rotation.

Abstract: Disclosed are prosthesis systems and methods that provide porous fixation rings by which the articulating surfaces of the implant can be exchanged such that the anatomic surfaces can be converted to reverse surfaces, while not exchanging the fixation components. Also disclosed herein are methods by which the surgeon can implant an inset anatomic articulating glenoid implant whereby at a later date, can remove the anatomic articulating surface and replace it with a reverse articulating surface such that the primary means of fixation remains well fixed in the glenoid fossa at the moment of articular exchange.

Abstract: In some aspects, a shoulder implant with improved joint mobility, includes a backing component, a neutral non-inclined bearing component, and a peg. The neutral non-inclined bearing component is located on a concave side of the backing component. The bearing component is made from a different material than the backing component and is configured to touch a glenosphere having a center of rotation, wherein the bearing component is substantially radially symmetrical. The peg extends from the backing component and is configured to be connected to a humeral stem. The longitudinal axis of the peg of the backing component is offset from the center of rotation of the glenosphere and the longitudinal axis of the backing component is aligned with the center of rotation of the glenosphere.
