Dual constraint elbow prosthesis

摘要

An artificial elbow has a humeral member and an ulnar member. A connecting segment has first and second ends. A first pin assembly connects the humeral member to the first end for pivotal rotation relative thereto in response to a first torque. A second pin assembly connects the ulnar member to the second end for pivotal rotation relative thereto in response to a second torque. The second torque is less than the first torque.
