The outcomes of collagen hydrolysis vs PTED effect for lumbar disc herniation


Lumbar disc herniation (LDH) is a common disease with an incidence of 1%-3%, usually manifested as low back pain radiating to the lower extremities, which seriously affects patients' quality of life. Collagen hydrolysis was effective in treating LDH, it makes the protrusion smaller or disappeared, relieving or resolving the compression of nerve root by the protrusion.Percutaneous transforaminal endoscopic discectomy (PTED) is a less invasive techniques to treat LDH. However, the outcomes of collagen hydrolysis vs PTED effect was still unknown.
