As the most fashionable procedure for disc removal, transforaminal surgery is a breakthrough in the treatment of intervertebral discs, as it allows for the effective removal of disc tissue under direct vision while maximizing minimally invasive. However, like other classical procedures, this surgical method has its advantages and disadvantages: I. Advantages: 1. Minimally invasive. The incision is 7 mm, the soft tissues are minimally invasive, and the bony structures are preserved intact. 2. Operation under direct vision. Through the endoscopic system, the surgical field of view is clearly displayed on the high-definition display, and every step of the operation is done under direct vision to ensure safety. 3.Local anesthesia. Communication with the patient throughout the operation. Patients who cannot tolerate general anesthesia can also achieve surgical treatment. 4.Immediate effect. After the surgery, the patient can feel the effect of the treatment and can go down to the floor after a few hours. Disadvantages: Not all cases are suitable for this type of surgery. Patients with foraminal stenosis, disc ossification, lumbar instability and spinal stenosis are not recommended or cannot be operated. As with all other simple disc removal procedures, the possibility of recurrence exists, but the recurrence rate is less than 1%.
