Lumbar disc fusion, i.e. lumbar vertebral body fusion, is generally not a big risk to regular hospitals. The risk lies in the possibility of lumbar back pain, vascular and nerve injuries, and accelerated degenerative lesions in the neighboring segments. 1. Lumbar pain: the surgical process can lead to local muscle tissue damage, while the generation of scarring in the spinal canal can cause spinal stenosis, thus inducing pain in the low back. 2. Vascular and nerve injury: the possibility of medical vascular and nerve injury during surgery cannot be ruled out, and there is a certain risk. 3. Accelerated degenerative disease of neighboring segments: lumbar vertebral body fusion can redistribute the force borne by the original segments of the spinal column, and increase the force of neighboring segments, thus accelerating the degenerative disease of neighboring segments. It is recommended to consult a doctor in time and choose an appropriate treatment plan under the guidance of a doctor according to one’s own condition.
