Procedure
To do this, the damaged tissue must be removed so that the nerve fibers can sprout again from the healthy tissue. In order for them to know where to grow, they need a guiding structure along which they can grow to their final organ. Nerves that can be taken from other parts of the body without major damage can serve as a guide structure. Blood vessels (veins) can also be sutured as a bridge between two nerve endings for short defect sections.
In the case of recent transections, the nerve endings should be sutured back together within a few days if possible. In this way, the piece of nerve that lies after the transection site can serve as a guide structure for the newly growing nerve fibers.
If painful neuromas have already developed following a nerve injury, these must also be removed. Here too, the defect area must be reconstructed afterwards.
