ABSTRACT:
Biocompatible metal balls are secured by affixation stems to the humerus and the scapular region of the shoulder. The balls are rotatably captured between a pair of cutout plastic hemispheres, which are secured to each other to form a spheroid by a metal shell. The prosthesis accordingly provides a wide range of articulation with substantially high stability.
