Brief summary (from the registry)
Lumbar disc herniation (LDH) is a common and frequently-occurring disease giving rise to low back pain and (or) leg pain. There are about 1.5 million people with LDH-related pain, accounting for 10% of outpatients each year in China. The mechanism of LDH-related pain is that the degeneration causes the protrusion of the intervertebral disc directly to the lower lumbar nerve root or spinal cord, and the chemical stimulation plays a key role in it. Currently, LDH treatments are mainly divided into conservative treatment, surgical treatment and minimally invasive treatment. The minimally invasive technique is a new technology that has been arising in recent years, with small wound, little bleeding and quick recovery. It mainly includes collagenase dissolving, laser decompression, radiofrequency ablation, etc. Intervertebral disc radiofrequency ablation is an early application of minimally invasive technique with a wide range of applications in a long time. The percutaneous transforaminal endoscopic discectomy (PTED) is a new technique, which is applied in clinics with shorter time, and the implementation and efficacy of the technique need to be further discussed. A case-control clinical trial is designed to compare the efficacy and safety of PTED with radiofrequency ablation in the treatment of LDH. Main outcome is Visual Analogue Scale for leg pain, secondary outcomes are Oswestry disability index, quality of life assessment, Burns Depression Checklist, recovery rate, complications, operation time and radiation exposure time, etc. The follow-up time points are 7 days, 1 month, 6 months and 12 months post-operation.
