IRCT20231121060129N1 IRCT 2023-12-11 Tabriz University of Medical Sciences Laser therapy in lumbar discopathy Investigation of the clinical effects of percutaneous laser disc decompression in the treatment of Lumbar Intervertebral Disc 2023-12-22 anticipated 36 Complete https://irct.ir/trial/73885 interventional Randomization: Not randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Blinding description: The target population includes all patients referred to the Imam Reza Hospital clinic with radicular pain caused by intervertebral disc herniation. Subjects are included in the study by considering the entry and exit criteria through non-random sampling. Then they are divided into intervention and control groups using RAS software using random block method with 2 and 4 blocks. Flow chart (Loss to follow up) will be mentioned. N/A Lumbar discopathy. Patients in the intervention group, after determining the affected areas of the lumbar spine, taking a history, physical examination, imaging such as MRI, CT scan and electromyography - nerve conduction velocity (EMG-NCV), in an outpatient setting, with injection A one-step needle into the disc space will be treated. Disc material is not removed. Instead, the nucleus pulposus will be vaporized by laser. Patients are treated with a 1000 J 980 nm diode laser (a product of LaserStar Technologies Corp, manufactured in Germany with a 200 micron fiber) at a power of 5 watts. After sterile skin preparation and dressing, the disc space is identified with the help of a C-arm fluoroscope. The craniocaudal movement of the fluoroscope tube defines the margin of the disc. The fluoroscope tube is rotated obliquely to bring the superior articular process to the midline, and a 7-inch 18-gauge needle is inserted immediately anterior to the superior articular process and superior to the transverse process through a triangular safe zone. Advancement with the C-fluoroscope arm is observed to be strong enough and of good quality to provide an overview of the area. When finished, the tip of the needle should be in the center of the disc..
