Treatment of dysesthesia of the sensory branch of the radial nerve by distal posterior interosseous neurectomy.
Complete injuries to the sensory branch of the radial nerve may lead to the development of an area of dysesthesia in the dorsoradial aspect of the hand. However, lesions of the radial nerve proximal to the elbow level, affecting both the sensory branch and the posterior interosseous nerve, will never develop an area of distal dysesthesia. Therefore, it seems likely that the dysesthesia observed in isolated injuries of the sensory branch of the radial nerve is transmitted to the cortical receptors through the intact posterior interosseous nerve. On the basis of the above clinical observations, we have successfully treated 43 patients with radial dysesthesia by division of the distal posterior interosseous nerve. There have been no complications or functional deficits related to this procedure.
