Development of Upper Extremity Complex Regional Pain Syndrome After Prolonged Surgery in Lithotomy Position: A Case Report.

Complex regional pain syndrome (CRPS) is a chronic condition commonly consisting of allodynia, paresthesias, skin and temperature changes, and motor dysfunction. CRPS is relatively rare and classically develops in a limb after sustaining a traumatic or surgical insult. To date, CRPS developing in a previously uninjured limb after prolonged immobilization has not yet been reported. We describe a 45-year-old man with no known preexisting injury or neuropathy to his upper extremities who developed CRPS of his right wrist and hand after prolonged colorectal surgery.
