Incidence of Complex regional pain syndrome after foot and ankle surgery

Random Friday by Marc Schmitz:

Complex regional pain syndrome (CRPS) is known as a neuropathic pain syndrome that can occur postoperatively as a complication of surgery or (micro-trauma). CRPS is an uncommon complication surgery, and it is characterized by severe pain, skin changes, and swelling. The natural history has been characterized by chronicity and relapses that can result in disability. 

The pathophysiology includes different mechanisms of motor, sensory, and autonomic dysfunction and is not entirely clear. The diagnosis of CRPS is made clinically, and no diagnostic tests are available. Little information is available in published studies regarding the types of patients who develop CRPS specifically in relation to foot and ankle surgery. The aim of this study was to determine the incidence of  CRPS in patients who had undergone foot and/or ankle surgery and to establish the patient factors associated with its development.

In conclusion, females and those with a history of anxiety or depression undergoing elective foot and ankle surgery should be counselled regarding the risks of developing CRPS during the  consent process > from Rewhorn et al., J Foot Ankle Surg 53 (2014) 256–258. All rights reserved by the American College of Foot and Ankle Surgeons.
