Pain
-
Traction lesions of the brachial plexus are becoming more frequent. Many of the lesions involve avulsion of nerve roots from the spinal cord. This very often results in severe pain which is associated with deafferentation. ⋯ The single most effective manoeuvre that reduces pain is absorption by the patient in work. There remains a significant number of young men with severe pain who may expect to suffer such pain indefinitely. There is urgent need for new methods to be developed to control this pain.
