Abstract
A method and apparatus for proper sizing and centralization of a shoulder humerus implant are provided. The method and apparatus replicate the proper stem height and position for a shoulder humerus implant, and may be used during trialing and maintaining the proper height and orientation during implantation. The apparatus further assists in maintaining the shoulder humerus implant stem at the center of the humeral canal to allow for proper cementing technique, and facilitates selection of the appropriate humeral head replacement.
Claims15
A shoulder proximal centralizer, comprising:
- a head wherein an attachment hole is located, the attachment hole is sized to match a stem neck of a shoulder humerus implant;
- a body extending from the head to an outer diameter to form a fan-like shape with a defined radius between 20 millimeters to 60 millimeters extending from the head to the outer diameter;
- a visualization window located towards a distal end of the body for visualization during surgery;
- a mid-panel separating the attachment hole and the visualization window, wherein an anti-rotation pin is located to mate with a shoulder humerus implant during use;
- and
- a distal end panel having a lip with a first thickness, and an outer end with a second thickness, the first thickness is greater than the second thickness.
