Appl. No.:

09/838698

Inventors:

N. Grusin - Memphis TN, US
Christopher Jobe - Redlands CA, US

Edward Duke - Bartlett TN, US

International Classification:

A61F002/40

US Classification:

623/019140

Abstract:

A modular humeral prostheses for replacement of the humeral head of a humerus. The prosthesis generally comprises a stem for insertion in the medullary canal of the humerus, a head for replacing the natural humeral head, and a connecting member for connecting the head to the stem. Specifically, the connecting member of the prosthesis and the engagement of the connecting member to the head provides varying degrees of eccentricity as desired.

Abstract:

A series of humeral stems, each stem including an axial bore and longitudinal slots along the distal end to allow for distal compression. The compression force necessary to compress the distal diameter of each stem varies by stem diameter. Thus, as the stem diameter increases through the series, the compression force decreases. The axial bore and longitudinal slots together form a series of stem segments that assume the shape of the medullary canal, reducing the force exerted upon the canal by the humeral stem.
