Prosthetic devices to improve the mechanics of the joint in knee arthroplasty

摘要

The prosthetic device of claim 13 wherein the proximal segment and the humeral stem are multiple modular segments disclosed herein is a kit that includes a humeral stem having a central longitudinal axis.The humeral stem configured to attach to the resected bone; the first tuberosity component having a first thickness relative to the central longitudinal axis of the humeral stem; the 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.Translation of the summary summary "prosthetic devices to improve the mechanics of the joint in knee arthroplasty" this invention relates to a kit that includes a shaft of humerus has a central longitudinal axis.The shaft of the humerus configured to attach to a bone dry; a first component of the tuberosity having a first thickness in relation to the longitudinal central axis of shaft of humerus; a second component having a second thickness tuberosity in relation to the central axis longitudina L of the shaft of the humerus.In the first thickness of the first component of the tuberosity is different from the second thickness of the second component of the tuberosity; and at least one of the proximal segment is configured to pick up, at least in the first component and the second component tuberosity of the tuberosity.In a form of realization, the first thickness of the first component of the tuberosity is at least 20 mm in relation to the central axis of the shaft of humerus, and the second thickness of the second component of the tuberosity is at least 20 mm in relation to the central axis of the shaft of the humerus.
