Brief summary (from the registry)
Low back pain is one of the most common musculoskeletal disorders affects individuals at least one during lifetime. Chronic low back pain (CLBP) lasts more than 3 months and decreases quality of life and causes work loss all over the world. Most common causes of Chronic Low back pain (CLBP) are lumbar disc herniation and/or degeneration, degenerative facet joints and sacroiliac joint pathologies, However, superior cluneal nerve (SCN) entrapment is another cause of CLBP that is ignored. It was reported that Superior cluneal nerve entrapment prevalence is % 1,6 - % 14 in CLBP patients. The Cluneal Nerves originate from the cutaneous branches of the dorsal ramus at T11-L4 and SCN innervates the skin of the upper part of the gluteal region. The nerves pass over the iliac crest through a tunnel formed by the thoracolumbar fascia and the upper edge of the iliac crest, that is the entrapment area. There are methods such as nerve blocks, neuromodulations and surgery in resistant cases. However, SCN entrapment is an overlooked diagnosis that should be considered in differential diagnosis. Recently, radiofrequency ablation (RFA) of the SCN was performed under fluoroscopic guidance, total of 78% of patients reported nearly full analgesia for an average of 3 months. Although ultrasound-guided imaging and blocking of SCN is well described, there was not enough study that shows the effectiveness of ultrasound-guided SCN RFA and compares it to conventional physical therapy (CPT) in the treatment of CLBP.
