AbstractAlthough there are many potentially effective therapeutic options for complex regional pain syndrome (CRPS), no definitive treatment exists. Therefore, patients often exhaust both medical and surgical treatment options attempting to find relief for their symptoms. As pain control and restoration of physical movement are primary treatment goals, strategies that include regional anesthesia techniques are commonly employed, but potentially underutilized, treatment modalities. The authors present a patient with refractory CRPS that had significant improvement in both pain control and the ability to tolerate intensive physical therapy following the placement of a superficial radial nerve catheter and an infusion of local anesthetic for 6 days as part of a multimodal analgesic regimen. This treatment approach also assisted in the decision-making process related to future treatment options. Although the use of regional anesthesia and perineural infusions of local anesthetic have previously been described as viable treatment options for CRPS, this case report represents the first known use of a superficial radial nerve catheter for treating CRPS as well as the first description of a technique for placing a superficial radial nerve (SRN) catheter using ultrasound guidance.
