**5. Conclusions**

Brachial plexus injuries continue to pose serious treatment dilemmas. Although the proximal injuries have a reasonable good prognosis, the distal ones not always get a good functional recovery. There has been a big improvement over the years, but research is needed to further improve the functional results, particularly in pan-brachial plexus avulsions. To start a new peripheral nerve unit is an exciting endeavor that demands enthusiasm, long-term commitment, and daily persistence.
