The superior and middle cluneal nerves are sources of low back, buttock, and leg pain. These nerves are cutaneous branches of the lateral branches of the dorsal rami of T11- S4. Pain arising from entrapment or dysfunction of one or more of these nerves is called "cluneal nerve syndrome." A clear understanding of the anatomy underlying cluneal nerve syndrome and its treatment has been hampered by the very small size of the cluneal nerves and their complex, varying anatomy. Because of differing methods and foci of investigation, the literature regarding cluneal nerves has been confusing and even contradictory. ⋯ Cluneal nerve syndrome is characterized by a triad of pain, tender points, and relief with local anesthetic injections. The pain is a deep, aching, poorly localized low back pain with variable involvement of the buttocks and/or legs. Tender points are localized at the iliac crest or caudal to the posterior superior iliac spine. Muscle weakness and dermatomal sensory changes are absent in cluneal nerve syndrome. If the pain returns after injections, neuroablation, nerve stimulation, or surgical release may be needed.

Postoperative Pain in Adolescent Idiopathic Scoliosis Surgery: A Randomized Controlled Trial.
Adolescent idiopathic scoliosis (AIS) is the most common type of scoliosis, and its treatment is essentially surgical for curves above 40 degrees. Posterior spinal instrumentation (PI) is the usual technique, while the vertebral body tethering (VBT) method is tested technique for this study as a new treatment option. ⋯ From our results, both techniques can be employed for AIS surgery, but a meticulous approach is essential for the prevention of acute pain for VBT.

Randomized Controlled Trial
Comparison of Changes in the Optic Nerve Sheath Diameter Following Thoracic Epidural Normal Saline Injection in Laparoscopic Surgery.
Thoracic epidural analgesia is useful for postoperative pain control after upper abdominal surgery. However, epidural analgesia in patients undergoing laparoscopic surgery may potentiate an increase in intracranial pressure (ICP). ICP can be effectively evaluated by measuring the optic nerve sheath diameter (ONSD). ⋯ The lapa-saline group showed the most pronounced increase in the ONSD. The ONSD values higher than 5.8 mm were observed only in the lapa-saline group. The increase in the ONSD continued even after the deflation of pneumoperitoneum only in the lapa-saline group.

Chronic neuropathic pain is a disabling condition that affects quality of life. Despite recommendations and guidelines, treatment remains suboptimal as it often does not result in significant symptom relief. Capsaicin 8% patch has been used for the treatment of several peripheral neuropathic pain etiologies with encouraging results. ⋯ Capsaicin 8% patch is a valuable option for the treatment of peripheral neuropathic pain, providing a significant reduction in pain intensity and painful area. It is well tolerated and has a high treatment compliance.Ethics Committee Reference Number: 16/16//04/2021.

Pudendal neuralgia (PN) is one of the most common forms of genital pain. Only 42.2% of PN patients respond to the first-line treatment. Novel neuromodulation techniques in the treatment of refractory PN patients are urgently required. ⋯ These data imply that SNS can have beneficial effects on patients with refractory PN.
