The load on the radius and ulna in different positions of the wrist and forearm. A cadaver study.
Nine cadaver specimens were tested with load cells attached to both sides of an osteotomy of the distal radius and ulna. The load along the radius relative to the ulna could be measured in different positions of the wrist and forearm. There was less load along the radius in a position of wrist flexion, ulnar deviation and full forearm pronation.
