Scoliosis is a disease that develops gradually and gets worse every year. Therefore early detection and early treatment are very important. Generally speaking, for adolescent idiopathic scoliosis of 40 to 60 degrees, if detected early, it can be corrected by relatively simple and safe surgery, when the treatment effect is the best, because the scoliosis is not very serious, and the spine is relatively soft, the surgery only requires the implantation of titanium screws in the key part of the spine, and the placement of corrective rods can be relatively easy to correct, the surgery is less risky, simple and safe. This time in the old revolutionary region of Jiangxi Ganzhou, the clinic received several patients with very serious scoliosis, these patients may have been diagnosed with scoliosis in other hospitals several years ago and recommended by doctors to operate, but perhaps due to negligence or family economic conditions, or perhaps concerns about surgery, scoliosis has now become quite serious. The degree of cobb angle between the two most inclined vertebrae of scoliosis is what we often call the degree of scoliosis And for this type of severe scoliosis, conventional techniques are not enough, and orthopedic spinal osteotomy surgery needs to be implemented. In layman’s terms, this means that the stiff and deformed spinal bones are amputated and reattached by special surgical tools to complete the orthosis. This is the most advanced technology in the treatment of severe spinal deformities – spinal osteotomy orthopedic technology. Can the spinal nerves be injured by osteotomy for scoliosis? Will it cause paralysis? Osteotomy for scoliosis may cause nerve damage. This is because compared to surgery without osteotomy, osteotomy involves an additional surgical step in which the bone around the nerve is splinted and removed using a special tool. This may have some contact with the nerve during the surgical operation, which in turn may damage the nerve, and the degree of delicacy of the osteotomy can be imagined. On the other hand, during osteotomy, the stiff and deformed spinal bones are amputated and then rejoined. During the joining process, the two bones may have docking problems, and if they are misaligned (which can happen even if the patient moves the limb during the recovery period), the nerves can be damaged. Therefore, osteotomy may injure the nerve, and the most serious consequence is paralysis. There are also patients who have abnormal nerve conduction during the recovery period when the nerve is in a normal state intraoperatively, and the limb is basically mobile for several days after surgery. So how can the surgeon prevent nerve injury during surgery? To prevent nerve injury, we often use measures such as nerve monitoring and arousal tests during surgery. Normally, the nerve has a current waveform on the display. If the surgeon touches the nerve during surgery, the wave amplitude on the display will generate an irritation signal, prompting the surgeon to avoid the location. Alternatively, the surgeon can actively send an electrical signal, for example, from the head to the muscles of the spine, and if this pathway is smooth, the nerve is not damaged. It’s actually continuous monitoring of the sensory nerves and having nerve monitoring all the way through the scoliosis surgery to protect you. Sometimes a brief intraoperative awakening of the patient is also performed to check the nerve conduction and the surgeon will adjust the details of the surgery according to the patient’s condition. Orthopedic spinal osteotomy, a very significant orthopedic procedure, often requires an experienced surgeon to master the surgical technique accurately. Choosing an experienced surgeon is the only way to ensure a safe surgery.
