Implantable elbow joint assembly with spherical inter-support

摘要

A multi-component elbow joint assembly incorporated into reconditioned end surfaces established between an upper humerus bone and opposing lower radius and ulna bones. The assembly includes a first component anchored into the upper humerus reconditioned end surface and exhibits a first exposed support surface. A second component is anchored into the lower reconditioned bone end surface of at least one of the radius and ulna bones and exhibits a second exposed support surface. An intermediate component is supported in at least one of eccentric or rotational fashion between the first and second anchored components.

1. A multi-component elbow joint assembly incorporated into reconditioned end surfaces established between an upper humerus bone and opposing lower radius and ulna bones, said assembly comprising:
a first component anchored into the upper humerus reconditioned end surface and exhibiting a first support surface; a second component anchored into the lower reconditioned bone end surface of at least one of the radius and ulna bones and exhibiting a second exposed support surface; an elongated and uneven roller shaped intermediate component supported in rotational fashion between said first and second anchored components; and each of said anchored components further exhibiting a concave surface for supporting therebetween said intermediate component, said anchored components each further having a widened uneven surface for supporting a corresponding uneven profile associated with said intermediate positioned roller shaped component.
