Deformities and Limitation of Motion of the Forearm

  • Benjamin Joseph


Pronation and supination are complex movements of the forearm that enable positioning the hand appropriately to execute functions related to the activities of daily living. Recent studies suggest that pronation and supination are not brought about by mere movement of the radius around a static ulna but entails movement of the radius, ulna, and the interosseous membrane (Weinberg et al. 2000; Nakamura et al. 1999). The integrity and normal structure of the proximal and distal radioulnar joints, the radius and ulna, the interosseous membrane, and the muscles that pronate and supinate the forearm are all needed for normal forearm motion. It follows that abnormalities in any of these structures can compromise pronation and supination (Ogino and Hikino 1987; Dal Monte et al. 1987; Yasutomi et al. 2002; Tynan et al. 2000; Price et al. 1990; Sibinski et al. 2007; Kreulen et al. 2007) (Fig. 28.1).

Supplementary material

Video 28.1

This child with a congenital radioulnar synostosis is attempting to comb his hair. The awkward way in which he does it is evident (MPG 4420 kb)

Video 28.2

The same child as in Video 23.1 is demonstrating how he gets his hand to his mouth. The excessive adduction and external rotation of the shoulder which are compensatory mechanisms are seen (MPG 4573 kb)

Video 28.3

The child is demonstrating how he mops his face and forehead (MPG 4830 kb)
