Irritation of the sinuvertebral nerve by a posterior or posterolateral disk desiccation can cause somatic referred pain that can mimic a lumbar radiculopathy. We present a case of a patient presenting with this condition and the positive result in pain improvement after endoscopic radiofrequency ablation of the sinuvertebral nerve. An 18-year-old Olympic runner presented to our clinic with back pain and left leg pain in a clear L5 distribution. He did not have a history of trauma. His imaging did not demonstrate any lesion causing compression of the left L5 nerve root as expected. He was found to have a left healing L5 pedicle fracture and ipsilateral chronic L5 pars interarticularis fracture. He was also found to have an ipsilateral minor left L5-S1 disk desiccation. His visual analog scale (VAS) score was 7. After a positive provocative diskogram, the patient underwent percutaneous transforaminal endoscopic radiofrequency ablation of the left L5 sinuvertebral nerve, which was irritated by the left L5-S1 disk desiccation. At his 6-month follow-up visit, the patient's VAS score was 1. It is important for clinicians to remember that back-associated leg pain can be caused by somatic referred pain because of irritation of the sinuvertebral nerve. Endoscopic radiofrequency of this nerve can be beneficial in pain control, but further randomized prospective trials are needed to study these techniques further.
