The state of the art in restoration of severed peripheral nerves is outlined. Discussion of the prerequisites for an optimal nerve-repair such as intraneural anatomy of peripheral nerves (topography of nerves in cross-section), techniques for preparation of nerve stumps, lesions in continuity, precise rotational orientation, nerve-suture, interfascicular dissection and nerve-grafting, including harvesting of autologous nerve grafts and finally the postoperative management after restoration of peripheral nerves are discussed.

The imaging of peripheral nerve lesions remains limited to the radiographic demonstration of secondary skeletal lesions in birth trauma, reflex sympathetic dystrophy, neuropathic arthropathy, leprosy, and congenital indifference to pain. Nerve root avulsions can be imaged directly and the newer imaging modalities now allow delineation of lesions that previously could not be studied using conventional radiography. ⋯ Imaging of peripheral nerve lesions remains in its infancy. With further refinement in the signal-to-noise ratio made possible by advances in MRI technology, we may be optimistic about future imaging of peripheral nerve pathology.
