Complex Regional Pain Syndrome Associated with Cervical Disc Protrusion and Foraminotomy

Abstract

Study Design: Case report. Objective: To report a previously undescribed association between complex regional pain syndrome (CRPS) and surgery for cervical disc protrusion. Summary of Background Data: Although CRPS has been associated with disc protrusion and lumbar spine surgery, there is no record in the literature of a similar association with cervical disc protrusion. Methods: Description of a clinical case. Results: A patient with radicular pain due to cervical disc protrusions underwent posterior foraminotomy, which did not relieve his pain. Within 3-4 weeks, he developed features of CRPS. Review at 16, 22, and 34 months revealed some, but limited, improvement. Conclusions: This case provides circumstantial evidence of a hitherto undescribed association between CRPS and cervical disc protrusion. The mechanism is elusive, but may involve damage to small nerves in or near the intervertebral foramina. Wiley Periodicals, Inc.
