    Abstract: One embodiment of the present invention relates to a prosthesis, comprising: an acetabular cup, wherein the cup has an open end and a closed end, wherein the open end of the cup is defined by a rim and wherein the rim has an outer facing surface; at least one cavity disposed in the rim, wherein the cavity extends from a first end of the cavity at the outer facing surface to a second end of the cavity that is towards the closed end of the cup, and wherein the cavity comprises an undercut at the second end of the cavity; a locking ring; and at least one tab extending from the locking ring, wherein the tab comprises a first leg and a second leg having a separation therebetween, wherein each leg has a first end and a second end, wherein the first end of each leg is at the locking ring, wherein the second end of the first leg comprises a tab protrusion, and wherein at least the second leg is resilient such that the separation between the first leg and the second leg is reduced when the second leg is deflected towards the first leg; wherein the locking ring is removably locked to the cup by placement of the locking ring adjacent the rim and insertion of the tab into the cavity such that the second leg presses against a sidewall of the cavity to initially deflect the second leg towards the first leg as the tab enters the cavity and the tab protrusion of the first leg is urged into the undercut by the second leg subsequently deflecting back away from the first leg.

    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.
