Cervical plexus nerve displacement

Transposition of nerve means that when the proximal end of the damaged nerve is severely damaged and cannot be repaired by other methods, another normal nerve is cut off by surgery, and the proximal end is repaired and anastomated with the distal end of the damaged nerve. Make it functionally compensated. This surgery requires repairing motor nerve damage with motor nerves, and repairing sensory nerve damage with sensory nerves. This can maximize nerve regeneration and restore normal functional dominance. In addition, it is also required to consider as far as possible in the selection of donor nerves. Loss of function due to lack of donor site nerves. Since the donor and recipient nerves have different original innervation functions, the central innervation and regulation after displacement suture requires an adaptation and functional reorganization and coordination process. Practice has proved that the plasticity of central nervous system function is better in children than in adults, and the plasticity in patients who perform fine hand manipulation is better than that of general manual workers. This is worth noting when selecting cases. It is precisely for the above reasons that for nerves that need to restore coordinated voluntary motor function, it is best to use the nerve bundles that innervate the cooperative muscles for anastomosis. For patients with long nerve defects during nerve transposition, to ensure nerve tension-free anastomosis, nerve transplantation can still be used for nerve repair. This kind of nerve transplantation must also follow the principles of motor nerve and motor nerve transplantation, sensory nerve and sensory nerve transplantation to ensure the effect of surgery. Nerve displacement refers to sacrificing a small number of secondary nerve functions to restore more important functions of the affected neuromuscular, that is, anastomosis of some secondary uninjured nerves directly or through nerve bridge transplantation to the injured nerve.
