Abstract
Autologous transplantation in brachial plexus injuries has become significantly more efficacious through increased knowledge of the microtopographic anatomy of the fascicle structures and the refinement of microneurosurgical techniques. Recovery of shoulder and upper arm functions can be achieved with autologous transplantation in the majority of patients under optimized conditions. However, attempts to restore forearm, hand and finger functions in this way have been disappointing so far. Therapeutic success is primarily governed by early decision making, selection of adequate surgical strategies and intensive and longlasting postoperative management.

Abstract
Neurotization procedures represent an important therapeutic option in patients with complete root avulsion due to traumatic brachial plexus injuries. A variety of normal donor nerves can be used, including intercostal nerves, accessory nerve, parts of the cervical plexus, phrenic nerve, and/or the contralateral C7 nerve root. The reconstructive neurotization procedure should be performed within 3-6 months following the trauma and, when successful, can lead to substantial improvement in motor function for the shoulder and upper arm and in sensory function for the forearm, hand and finger region. Neurotization can also be combined with neurolysis and/or transplantation to restore upper limb motor and sensory function in order to achieve greater therapeutic benefit for patients with posttraumatic brachial plexus lesions.

Abstract
The occurrence of sever pain is one of the most disabling symptoms after the traumatic lesion of the brachial plexus. Avulsion of one or more cervical roots of the brachial plexus is the main cause of severe pain, known as deafferentation pain. Lesion of the dorsal horn of the cervical spinal cord due to root avulsion may lead to important pathological changes and scarring that are responsible for the induction of pain sensations. Different medical and surgical treatment modalities have been established to relief such pain after brachial plexus injury. In contrast to drug therapy, which usually offers only limited benefit, surgical treatment over the last years has shown positive results. Coagulation of the dorsal root entry zone (DREZ) is one of the most efficient surgical treatments for these patients. Understanding of the pathophysiological changes and different pain mechanisms induced by traumatic injury of the brachial plexus is fundamental for the planning and step-wise treatment of such patients.
