What is the result of taking nerve grafts from the legs to reconstruct the brachial plexus injury?

There is no real deleterious effect from removing the sural nerve grafts, except for minor scarring on the posterior aspect of the leg. Occasionally there is a small area of numbness on the foot; however, it is extremely unusual for a patient to even notice. In our experience, we have never encountered a complication or a complaint aside from the scarring.
