Disc chemolysis is the use of collagenase, a specific substance for dissolving intervertebral discs, which is injected into or on the surface of the herniated discs in CT or X-ray C-arm imaging interventions to combine with the collagen tissue of the discs, causing the collagen molecules to break down and be absorbed, so that the herniated discs will become smaller, achieving the goal of similar surgical resection and relieving the herniated discs of the oppression and irritation of the nerve roots, thus leading to the cure of the herniated discs. Thus, the herniated disc can be cured. This method is characterized by safety, certainty of efficacy, small trauma, low cost, etc. It is one of the advanced minimally invasive interventional techniques at home and abroad, which can make most of the patients with cervical and intervertebral disc herniation exempt from surgery. Advantages: It can quickly eliminate the pain caused by herniated disc, and the cure rate is more than 90% in 3-month follow-up. Disadvantages: It requires doctors to have excellent puncture skills and is not easy to be popularized at the grassroots level.
