When a patient has lumbar spinal stenosis, orthopedic surgery is generally not allowed. This is because lumbar spinal stenosis is a bony stenosis, which can easily cause the spinal nerve roots in the spinal canal to be compressed, leading to pain and numbness in both lower limbs. If orthopedic treatment is performed, the bony stenosis may lead to repeated irritation of the spinal cord and nerve roots in the spinal canal, which will aggravate the patient’s symptoms and may lead to paralysis of both lower limbs. Therefore, patients with lumbar spinal stenosis should not undergo orthopedic treatment, which may aggravate the patient’s clinical symptoms, while lumbar spinal stenosis, if more serious, may lead to spinal cord injury during orthopedic treatment. When lumbar spinal stenosis occurs, it is necessary to seek medical treatment in time, standardized treatment by the doctor, do not blindly self-treatment, so as not to cause adverse consequences.
