Contralateral c7 transfer for treatment of brachial plexus root avulsion.
Since the first report of the clinical application of contralateral C7 transfer, this procedure has become widely accepted and is used in the treatment of brachial plexus root avulsion injuries. The technique of this procedure has been markedly improved during the past years. The prespinal route may lead to a shorter nerve graft or even to direct coaptation. The results differ a lot from the different studies. There are many factors affecting the results of contralateral C7 transfer, such as age, time for regeneration and techniques of contralateral C7 transfer. Although dividing C7 will not cause a permanent loss in sensory and motor function of the healthy limb, it is worth pointing out that the C7 transection level should not be too distal, otherwise the fibers from the upper and lower trunk could be injured and permanent motor and sensory deficits may occur. Also, the surgeons should balance the risks and benefits for the patient before making the decision to operate in this manner.
