Total Elbow Arthroplasty System
US Patent:
6306171, Oct 23, 2001
Filed:
Apr 4, 2000
Appl. No.:
9/543160
Inventors:
Michael G. Conzemius - Ames IA
Assignee:
Iowa State University Research Foundation, Inc. - Ames IA
International Classification:
A61F 258, A61F 230
US Classification:
623 2011
Abstract:
A total elbow arthroplasty system, incorporating a humeral component, a radial component and a ball component, may be used as a total elbow replacement in the canine, as well as in other species. The implant of the present invention has an isometric humeral component and an isometric radial component. An isometric ball component having an isometric articular surface is mounted on the radial component. The humeral and radial components have stems for mounting in the medullary canals of the respective bones, which are angled so as to approximate the configuration of the original humerus and radius. The components work together to form a nonconstrained ball and socket joint. The invention is also directed to methods for implanting the novel endoprosthesis of the present invention in a canine elbow joint. The apparatus and methods of the present invention are useful in the treatment of elbow osteoarthritis in canines, as well as in other species, including other quadrupeds and humans.

Abstract:
The present invention is directed to novel two piece total elbow arthroplasty systems. In particular, the present invention is directed to total elbow implants, bone cutting guides for the installation of the implants, and methods for total elbow replacement. The apparatus and methods of the present invention are useful in the treatment of elbow osteoarthritis in canines, as well as in other species, including other quadrupeds and humans. The two piece implant of the present invention has an isometric humeral component and a radioulnar component that has an isometric articular surface. The components have stems for mounting in the medullary canals of the respective bones, which are angled so as to approximate the configuration of the original humerus, radius and ulna. In addition, novel cutting guides are provided to facilitate the removal of arthritic cartilage and a minimal amount of adjacent bone, thereby allowing the implantation of the two components (humeral and radioulnar), which are held in place by cement, such as polymethylmethylacrylate (PMMA). The result is a pain-free joint that has a near normal range of motion.
