Abstract.
Stress distribution in the humeroradial joint was analyzed with pressure-sensitive film, a tactile sensor, and by the three-dimensional finite element method. Fifteen cadaveric elbows with minimal osteoarthritic changes were loaded perpendicular to the articular surface of the radial head in the full pronation, supination, and neutral positions from 0° to 90°. Finite element analysis of stress distribution in the joint was based on a model of the same conditions. The patterns of stress distribution were similar with all three analysis methods. High stress was concentrated laterally in supination, and medially in the neutral and pronation positions. The results of the analyses closely resembled those found in some studies of the pathophysiology of degenerative changes in the humeroradial joint.
