Effects of Prosthesis Shape and Material on the Contact Mechanics of Elbow Joints Following Radial Head Arthroplasty: An In-Silico Investigation.

The lower contact areas, higher contact stresses, and lower stresses at the radial neck observed in the presence of most axisymmetric RHPs and anatomic Cobalt RHP can be correlated to postoperative complications. The findings suggest that polymeric anatomical RHPs may be superior to conventional metallic axisymmetric options in preserving elbow biomechanics and reducing postoperative complications. However, their long-term effects need to be further explored.
