Abstract: In some embodiments, the present invention provides a reverse shoulder glenoid prosthesis which supports the attachment of multiple different types of modular attachments that can: 1) provide additional scapular fixation (ie external to the glenoid) in order to improve glenoid implant fixation in cases of severe bone loss/fracture, 2) provide joint line lateralization to improve tissue stability in cases of severe glenoid/scapula bone loss, 3) facilitate use and containment of glenoid bone graft in cases of severe glenoid/scapula bone loss—particularly in those cases in which the glenoid defect is uncontained/peripheral 4) achieve glenoid fixation while at the same time reconstructing the scapular bone in cases of scapula fractures, glenoid fractures, and/or acromial fractures, and 5) provide improved rTSA joint biomechanics, particularly posterior rotator cuff efficiency by changing the line of action of the infraspinatus and teres minor muscles to improve their muscle tension, and also increase each muscle's external rotation and abduction moment arm lengths.

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: Adaptable medical trays are disclosed herein. An adaptable medical tray includes a first component medical tray having a plurality of walls, a bottom, and a removable top, the plurality of walls and the bottom arranged to form a cavity in the first component medical tray; and a second component medical tray removably coupled to the first component medical tray, the second component medical tray including a plurality of walls, a bottom, and a removable top, the plurality of walls and the bottom arranged to form a cavity in the second component medical tray. The first component medical tray and the second component medical tray are constructed of a sterilizable material and the first component medical tray is decouplable from the second component medical tray after a sterilization process without removing the removable tops from the cavities.

IPC: A61B17/88
Abstract: A device including a first plate configured to interface with a first bone structure of a joint; a second plate configured to interface with a second bone structure of the joint opposite the first bone structure; and at least one mechanical actuation mechanism disposed between the first plate and the second plate and configured to apply a distraction force along an axis between the first plate and the second plate so as to urge the first plate and the second plate away from one another, wherein the device is configured so as to have a range of motion ranging from a minimum distance between the first plate and the second plate to a maximum distance between the first plate and the second plate, and wherein the mechanical actuation mechanism is configured such that the distraction force is substantially constant distraction force across the range of motion.
