Nerve Lesions

As far as nerve anatomy and the classification of nerve injuries is concerned we may look at the classic works by Seddon,6 Sunderland,7 Dellon8 and Lundborg9 and others.

From a clinical point of view, nerve injuries may be classified in various ways depending on the etiology (mechanical, thermal, ischemic, chemical) and on the way they arise (acute, chronic) the most frequent being the acute post traumatic lesions presenting an increasing incidence, due to road and work place accidents. The effects of a traumatic lesion on a nerve may be divided into 6 groups as classically stated by Sunderland (Table 2.1). Here we will examine the microsurgical reconstruction of severely damaged nerves, unable to obtain a spontaneous recovery.

The surgical treatment of these lesions must take into consideration the various factors which condition nerve regeneration. Therefore, the different techniques of nerve repair are described through the analysis of these factors together with the indications for the treatment of peripheral nerve injuries.
