Dermatosensory Peripheral Nerve Interfaces: Prevention of Pain Recurrence Following Sensory Neurectomy.

Chronic pain is a significant health care problem. Many patients' pain can be linked to a neuropathic origin, diagnosed with a thorough history and physical examination, and confirmed with a diagnostic nerve block. There are new procedures designed to address neuropathic pain from symptomatic neuromas by providing physiologic targets for regenerating axons following neurectomy. Dermal wrapping of the end of a sensory nerve following transection, a technique called dermatosensory peripheral nerve interface, may provide an optimal environment to prevent neuroma pain and reduce chronic neuropathic pain.
