Abstract
Traction injuries of the brachial plexus usually result in avulsion of the anterior and posterior roots from the spinal cord since these represent the weakest link in the plexus.3 This type of injury presents sufficiently characteristic electromyographic findings so that the site of the lesion can be accurately localized to the spinal canal (proximal to the level of the dorsal root ganglion).1,5 These findings depend on the functional integrity of the peripheral sensory axons which remain in continuity with the dorsal root ganglion. The motor axons, on the other hand, undergo Wallerian degeneration. The absence of Wallerian degeneration in the peripheral sensory axons is reflected by a normal evoked sensory nerve action potential during nerve conduction studies in spite of complete anesthesia of the involved extremity.
We are reporting the electromyographic data recorded from two patients with brachial plexus root avulsion.
