Complex regional pain syndrome (CRPS) is a multifaceted, progressive, and potentially devastating disorder generally affecting the extremities. In addition, scant information is available regarding the types of patients who develop lower-extremity CRPS. This is a retrospective chart review study of 64 patients who presented to a pain clinic with CRPS of the lower extremity. ⋯ The most common inciting surgical events were bunionectomy, tarsal tunnel release, and heel-spur surgery. Referral to the pain clinic was delayed more commonly in trauma patients than in postsurgical patients, with a corresponding increase in pain clinic visits for treatment. This study may act as a guide for physicians treating the lower extremity to aid in the recognition of lower extremity complex regional pain syndrome and its characteristics.
