Abstract: Disclosed is a prosthetic augment designed to reconstruct a lateral tuberosity shape of a humerus in a subject having proximal bone loss that includes a humeral adapter tray configured to connect a humeral liner of a reverse shoulder prosthesis to a humeral stem of the reverse shoulder prosthesis and an augment member having a first face adapted for contacting the humeral stem of the reverse shoulder prosthesis and a second face adapted for contacting an underside of a muscle, wherein at least a portion of the second face includes a bulbous surface adapted to alter a wrapping angle of the muscle around the lateral tuberosity, and wherein the second face has a radius of curvature selected from one of a constant radius of curvature or a variable radius of curvature.

Abstract: An apparatus includes a processor and a non-transitory memory. The processor is configured to receive pre-operative patient specific data. The pre-operative patient specific data is inputted to a first machine learning model to determine a first predicted post-operative joint performance data output including first predicted post-operative outcome metrics. A reconstruction plan of the joint of the patient is generated based on a medical image of the joint, and at least one arthroplasty surgical parameter obtained from the user. The at least one arthroplasty surgical parameter is inputted into a second machine learning model to determine a second predicted post-operative joint performance data output including second predicted post-operative outcome metrics. The second predicted post-operative joint performance data output is updated to include an arthroplasty surgery recommendation, in response to the user varying the at least one arthroplasty surgical parameter, before the arthroplasty surgery, during the arthroplasty surgery, or both.

Abstract: Disclosed herein are components of a reverse shoulder prosthesis. In an embodiment, a reverse shoulder prosthesis includes a humeral adapter tray configured to sit near a resected surface of a humerus, the humeral adapter tray comprising: a cavity; a central bore; and a distal face including a boss, the boss: (i) configured as an extension of the distal face, (ii) posteriorly offset from the central bore by at least 10 mm, and (iii) configured to engage a humeral stem; and a humeral liner comprising: a distal rim configured to sit within the cavity of the humeral adapter tray; and a concave articulating surface configured to mate with a convex articulating surface of a glenosphere. In an embodiment, the boss, in addition to being posteriorly offset, is superiorly offset from the central bore by at least 8 mm. In an embodiment, the reverse shoulder a humeral stem which engages the boss.
