The effect of distal radial and ulnar length change on forearm bone loading is not well understood during simulated dynamic wrist loading. This thesis presents two studies which investigate the effect of these length changes on distal forearm loading under simulated dynamic wrist motion. The first study investigates the effect of radial length change on axial loading at the distal radius and ulna and relationship between ulnar variance and distal forearm loading. The complex variation in axial loads in the distal radius and during length change and dynamic wrist motion were studied and discussed. There was no correlation between native variance and distal loads. The second study investigates the effect of ulnar change on axial loading at the distal radius and ulna and the effect of triangular fibrocartilage ligament complex (TFCC) on this relationship. Variation in axial loads during ulnar lengthening followed similar trends to radial shortening and vice versa.
