Complex regional pain syndrome and NTOS

Abstract

Complex regional pain syndrome (CRPS) is a chronic pain condition with defined diagnostic criteria that occasionally develops following an injury. It may develop in NTOS patients following the initial traumatic event resulting in both nerve injury and compression within the thoracic outlet, or from intraoperative nerve injury during treatment of NTOS. Both are rare occurrences, but this chapter will explore the possible mechanisms involved in CRPS.
