Recently, our pain department successfully performed transforaminal minimally invasive surgery for 2 patients with lumbar disc herniation. One patient, female, 57 years old, was admitted to the hospital with lumbar pain with radiating pain in the left lower limb for 15 years, which had been aggravated for one year, and was diagnosed with “lumbar disc herniation (L4-5)” after lumbar spine MRI examination showed herniation of L4-5 intervertebral discs with part of the calcification. Another patient, male, 34 years old, had lumbar pain with radiating pain in the right lower limb for more than 1 year, and was admitted to the hospital with the diagnosis of “lumbar disc herniation (L5-S1)” after MRI examination of the lumbar spine showed a huge herniated intervertebral disc with prolapse in the L5-S1 intervertebral disc. Both patients had been repeatedly treated with conservative treatment for many times, and the patients themselves were afraid of open surgery, and had been taking non-steroidal anti-inflammatory drugs for a long time, which made the treatment unsatisfactory. Under the leadership of Director Zhang Fei-e of the Pain Management Department, after careful preoperative preparation, transforaminal foramenoscopic disc removal surgery was successfully completed for the two patients, with a small incision of about 7mm and bleeding of no more than 20 ml. The patients’ pain and numbness in the lower limbs disappeared after the surgery, and they could get up and move around the next day, and all of them recovered and were discharged from the hospital within a week after the surgery. Minimally invasive transforaminal surgery for lumbar disc herniation is currently the most minimally invasive and effective treatment for lumbar disc herniation, the advantage is that there is no need for incision, percutaneous puncture, enlargement of the intervertebral foramen, the endoscope, i.e., the laminoscope, is placed into a specific location of the spinal canal, and the dural sacs, the nerve roots, and the protruding discs can be clearly seen under the direct visualization on the monitor, and the protruding nucleus pulposus is removed through the special forceps, thus fundamentally relieving the pain and numbness to the nerves and the herniated discs. The pressure on the nerve root is fundamentally relieved and the ruptured annulus fibrosus is repaired. The surgery is not only less traumatic, short time, less bleeding, but also obvious effect, after the operation, the back and leg pain can be relieved immediately, and you can be discharged from the hospital in 3 days, which really achieves the surgical purpose of “achieving the best therapeutic effect with the least pain”.
