Abstract: A proximal portion of an implant for repairing a multipart fracture of a proximal humerus includes an asymmetric body having a proximal end, a distal end, a medial side, a lateral side, an anterior edge, and a posterior edge a medial surface extending along Sat least a portion of the medial side and having a proximal end and a distal end; a protrusion forming the lateral side of the asymmetric body, offset in an anterior direction, and pointing toward a bicipital groove of the humerus when the proximal portion is implanted in the humerus, an anterior support surface configured to support a lesser tuberosity; a posterior support surface configured to support a greater tuberosity; an angled surface having a first side defined by the medial surface, a second side defined by the anterior support surface, and a third side defined by the posterior support surface; and an anchoring point.

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 herein is a kit that includes a humeral stem having a central longitudinal axis, the humeral stem configured to attach to a resected bone; a first tuberosity component having a first thickness relative to the central longitudinal axis of the humeral stem; a second tuberosity component having a second thickness relative to the central longitudinal axis of the humeral stem, wherein the first thickness of the first tuberosity component is different than the second thickness of the second tuberosity component; and at least one proximal segment configured to engage at least one of the first tuberosity component and the second tuberosity component. In an embodiment, the first thickness of the first tuberosity component is at least 20 mm relative to the central axis of the humeral stem, and the second thickness of the second tuberosity component is at least 20 mm relative to the central axis of the humeral stem.
