“…One cause of LBP that often localizes to the iliac crest and the buttock region is superior cluneal nerve entrapment. The superior cluneal nerves are sensory nerves that consist of cutaneous branches of the posterior rami of the T11-L5 nerve roots [ 4 ]. These nerves run from superior-medial to inferior-lateral and penetrate the thoracolumbar fascia at the iliac crest.…”

Low back pain (LBP) is a common complaint that can be nonspecific. Superior cluneal nerve entrapment should be included in the differential for LBP because, without a precise diagnosis, treatment may be less effective. A 61-year-old female with a history of chronic LBP and sacroiliac (SI) pain requiring opioids for pain control presented with minimal relief following SI joint fusion. Physical exam showed tenderness over the iliac crest with burning, radicular pain into the buttock. The patient received a superior cluneal nerve injection of local anesthetic that provided 100% pain relief for 72 hours without the use of opioids and no complaints of burning or radicular pain. This confirmed the diagnosis of superior cluneal nerve entrapment syndrome causing superior cluneal neuralgia. Superior cluneal nerve entrapment syndrome should be considered when evaluating causes of LBP to avoid unnecessary procedures and reduce the use of opioids.

“… 3 However, unlike a central motor nerve injury or nerve root radiculopathy, patients lacked abnormal deep tendon reflexes, muscle weakness, or abnormal Babinski reflex. 4 In addition, there was also a lack of tenderness over the vertebrae or costovertebral angles.…”

“…10 Surgical treatment involves making an incision over the posterior iliac crest about seven centimeters from midline, dissecting down to the fascia, and opening the fascia surrounding the branches as they cross over the iliac crest. 4 Surgical pathology of SCN entrapment syndrome reveals enlarged nerve branches with decreased myelinated fiber density, increased thinly myelinated fibers, perineural thickening, subperineural edema, and Renaut bodies. 11 Although awareness is increasing in the adult population, little attention has been paid to this pain disorder in adolescents.…”

Superior Cluneal Nerve Entrapment Syndrome: Thought to Be Spondylolysis

A rare but typically overlooked diagnosis in the orthopaedic surgery community is superior cluneal nerve (SCN) entrapment syndrome. The cluneal nerves function as purely sensory fibers, and the SCNs provide cutaneous innervation to the posterior parasacral, gluteal, and posterolateral thigh regions. When irritated, this syndrome can cause acute and chronic lower back pain and lower extremity symptoms. A 14-year-old adolescent girl presented to the clinic for an evaluation of pain in the right side of her lower back. The patient's physical examination showed tenderness to palpation on the right posterior iliac crest seven centimeters from the midline. Her neurologic examination demonstrated normal deep tendon reflexes, muscle strength, and sensation in the L2-S1 dermatomal distribution. Although imaging showed evidence of a left L5 spondylolysis, she responded positively to a steroid injection over the posterior iliac crest but negatively to one over the L5 pars defect. She later underwent a right SCN decompression surgery. After the procedure, she reported at least 90% improvement in her pain and rated it as a one in severity, on a scale of 0 to 10. Research regarding SCN entrapment syndrome has increased in the past several years. However, most of these studies are limited to the adult population. Therefore, more reports highlighting the potential for this syndrome in adolescents are needed as well.
