Cluneal Nerve Entrapment and Low Back Pain Management

Cluneal nerve entrapment is an under-recognised cause of chronic low back pain, arising when sensory fibres of the superior cluneal nerves become compressed as they traverse fascial tunnels over the iliac crest. These nerves, originating from dorsal rami of T11–L5, pierce the thoracolumbar fascia to innervate the skin of the upper buttock. Entrapment may manifest as axial lumbar discomfort, buttock pain and occasional proximal leg symptoms. Diagnosis hinges on a focussed clinical examination, marked by a tender point roughly 7 cm lateral to the midline on the posterior iliac crest and confirmed by temporary relief following a diagnostic block. High-resolution ultrasonography can delineate nerve courses but is not yet universally adopted. Management strategies range from conservative measures—lumbar stabilisation exercises, targeted physiotherapy and ergonomic advice—to interventional techniques including ultrasound-guided hydrodissection, local anaesthetic or steroid injections, and, when refractory, surgical decompression. More recently, peripheral nerve stimulation has shown promise in cases unresponsive to conventional therapy. A multidisciplinary pathway, integrating accurate diagnosis with individualised treatment, is pivotal to reducing misdiagnosis and improving patient outcomes.

Cluneal Nerve Entrapment and Low Back Pain Management publication trend

The graph below shows the total number of articles in cluneal nerve entrapment and low back pain management across all publications each year (not limited to Nature Index journals).

Technical terms

Superior cluneal nerve: Sensory branch of the posterior primary rami (T11–L5) that pierces the thoracolumbar fascia to innervate the skin over the upper buttock.

Hydrodissection: Technique involving perineural injection of fluid to separate nerve fibres from surrounding tissues and relieve entrapment.

Peripheral nerve stimulation: Neuromodulation approach that delivers electrical impulses to peripheral nerves to modulate pain signalling.
