Abstract
This paper reports experimental work in rats in which the radial nerve was cut at its origin from the brachial plexus and connected by means of a nerve graft to the corticospinal tract of the spinal cord at the T3–T4 level. After surgery, the triceps and extensor muscles of the forearm were able to extend the elbow and the wrist and gave almost normal responses on EMG. This reinnervation was no longer cholinergic, as demonstrated by the Vecuronium test. Because of the drawbacks associated with implantation into the spinal cord, this technique could not be used in all cases of total avulsion of the brachial plexus but it might be useful in those rare cases in which avulsion of all the cervical nerves of the brachial plexus is associated with paraplegia: such cases are rare but are occasionally seen.
