Low back and leg pain is common in middle-aged and older adults over the age of 45. Among them, lumbar disc herniation is one of the most common causes of low back pain, accounting for 20% of the total. The so-called lumbar disc herniation is when the lumbar intervertebral disc ages, the annulus fibrosus ruptures, the nucleus pulposus protrudes and squeezes the nerve roots, thus causing back and leg pain and nerve dysfunction. Such patients often have a history of acute lumbar injury, with recurrent episodes of lumbar and leg pain, sometimes accompanied by radiating pain in the lower extremities, usually unilateral, and the symptoms are aggravated when coughing, sneezing and bending, and may be alleviated by bed rest. Generally speaking, when middle-aged and elderly people have low back pain or lower limb pain and numbness, doctors first suspect lumbar disc herniation, and the diagnosis can be confirmed by CT and MRI examinations of the lumbar spine. Routinely, the doctor will advise the patient to undergo conservative treatment first, by means of traction, massage, acupuncture, physiotherapy and, in severe pain, closure. If the symptoms still do not reduce, or even worsen, many people will go to orthopedics. Surgery may not stop the pain Currently, the main treatment in orthopedics is the surgical removal of the herniated disc. If the surgery is successful, the symptoms will disappear, but this surgery is very invasive and damages the bones of the lumbar spine and the surrounding soft tissues very badly, which is difficult for many people with poor physical fitness to tolerate. With the development of medical technology, people have gained a new understanding of lumbar disc herniation. It has been discovered that compression of the surrounding nerves by a herniated disc is not the only cause of pain, numbness and other discomfort symptoms. In some patients, CT or MRI examinations reveal that the herniated disc is not very strong, but the symptoms are severe, mainly due to the herniated or degenerated disc producing some inflammatory substances that irritate the surrounding nerve roots. For such patients, even if the herniated disc is surgically removed, the inflammatory substances produced by the disc do not disappear and the symptoms will not be relieved naturally. Minimally invasive intervention first stops the pain and then dissolves the disc. Therefore, if you have a lumbar disc herniation and the conservative treatment does not work well, but you do not want to go to orthopedics for surgery, what should you do? In recent years, the minimally invasive interventional method carried out by the pain department can solve the above problem well and has formed a major feature. For patients with herniated discs, the doctor uses a needle to penetrate the patient’s spinal canal under the guidance of CT or C-arm imaging, and then places a very thin catheter through the needle and allows the catheter to reach the “problem disc” precisely. A drug pump is attached to the outside of this catheter, and the drug pump continuously injects anti-inflammatory and analgesic drugs into the diseased disc. After the inflammation of the disc is eliminated, a drug called collagenase is injected into it, which dissolves the herniated disc, and the patient’s symptoms disappear. Moreover, even if this treatment does not work well, the patient can still opt for orthopedic surgery, and the results of the surgery will not be affected. It is important to note that before going to the pain department for minimally invasive interventional treatment, one cannot eat seafood, and patients who have been taking anticoagulant drugs such as aspirin and warfarin for a long time must stop taking these drugs one week before treatment; when using drugs to dissolve the disc, one must be absolutely bedridden for 48 hours; after the treatment is completed and discharged from the hospital, even if the symptoms disappear, one cannot engage in strenuous exercise for three months, do not sleep on a mattress that is too soft, and wear a lumbar brace when walking.
