Management of acute lower extremity nerve injuries.

While repair of acute nerve injuries in the lower extremity has not been as aggressive as in the upper extremity, there should now be more effective early intervention. Newer microsurgical techniques can be used along with increased understanding of peripheral nerve internal anatomy to obtain more satisfactory repair and reconstruction of the injured nerves. The anatomy and vulnerability of the nerves in the leg are reviewed, and the decision process is analyzed in the context of the functional deficits following such injuries. A priority of goals in lower extremity nerve repair should be established to ensure salvage of the foot.
