Patients with low back and leg pain are most commonly seen in orthopedic clinics and online, and the leading cause of this is lumbar disc herniation. The medical diagnosis is lumbar disc herniation. This disease gives patients the feeling that conservative treatment is prone to recurrence and complete cure is difficult, but they are afraid of surgery, so they put it off again and again, which is very painful. Therefore, many patients will ask at the consultation, “Can this disease be cured? Do you need surgery? Will it be paralyzed? Is it very traumatic? Is the recovery time long? And so on a series of questions. To answer these questions, we first need to have a scientific understanding of lumbar disc herniation. The human spine is made up of several vertebrae, and between the two vertebrae there is a disc-shaped elastic cushion, which is surrounded by a fibrous ring and ligaments, and this disc-shaped cushion is what we call the intervertebral disc. It can play the role of cushioning pressure. Humans are upright animals, in the standing position or sitting position, the greater the pressure on the intervertebral disc, especially the lumbar disc is more obvious. As the human body ages, the intervertebral disc degenerates (this process begins after the second decade of our lives) or acute trauma and chronic accumulation of trauma causes the rupture of the annulus fibrosus, resulting in the protrusion of the nucleus pulposus of the intervertebral disc and compression or stimulation of the nerve roots on both sides caused by sciatica and a series of symptoms of lumbar pain, compression over time, the nerve will degenerate or even necrosis, clinical numbness of the lower limbs will appear Even the symptoms of muscle weakness. It is the common orthopedic disease – lumbar disc herniation. A diagnosis of lumbar disc herniation can only be made when the clinical history, signs (physical examination findings) and imaging evidence are consistent. For most patients with lumbar disc herniation the first option is conservative treatment. For patients who have a herniated disc for the first time, traction, physiotherapy, medication and strict bed rest for about 1 week can be chosen for the acute onset of pain and a gradual return to normal work and life after 6 weeks. If conservative treatment fails, surgery is the only effective way to relieve pain in the short term and prevent further nerve compression and degenerative necrosis. Minimally invasive intervertebral disc surgery is favored by patients for its advantages of less trauma and faster recovery. Transdiscoscopic lumbar disc removal is the safest and most effective form of minimally invasive disc surgery. It uses advanced tools such as discoscopy to perform the surgery, making a small hole in the herniated disc segment with an opener, placing a working set of a-tubes, introducing a miniature disc camera and light source, and magnifying the surgical surface more than 60 times to remove the nucleus pulposus on a 17-inch display. The operation can be done under the guidance of a slim digital endoscope without the large incision and extensive stripping of normal tissues such as paravertebral muscles and ligaments necessary for conventional open surgery. Accidental injury can be avoided because of the micro digital camera system that tracks the entire procedure and magnifies the surgical surface 64 times and projects it on the display through fiber optic transmission, so that the neurovascular vessels are clearly visible. A successful procedure allows the patient to be out of bed within a day or two and back to work within 3 weeks. For an experienced spine specialist, the success rate of the procedure is over 95%. Since 2002, the department has carried out transdiscaloscopic lumbar disc removal and has relieved a large number of patients without any surgical complications. over the past 10 years, the department has devoted itself to the development of minimally invasive spine surgery and has continuously innovated, carrying out a series of new techniques such as percutaneous balloon-expanded vertebral body retrobulbar plasty for osteoporotic spine fractures in the elderly and percutaneous pedicle screw fixation technique, making its minimally invasive spine surgery techniques It is at the forefront of the province. Nowadays, minimally invasive spine surgery has become one of the main specialties and research directions of the department.
