Loss of radiál nerve function causes significant limitation of hand usage. A patient is not able to extend the- ir wrist, fingers and thumbs, and consequently has great problems gripping objects. Gripping objects and poor grip strength, as a result of extension loss in the wrist, are the most difficult handicaps for the patient. In cases where the effect of nerve reconstructions implies worse functional results, a tendon transfer - which eliminates the potential negative results of nerve restoration - should be carried out as part of these proce- dures.
