Lumbar herniation fusion for the elderly is a surgical procedure that involves the removal of a lumbar disc followed by a bone graft fusion to fix the upper and lower vertebrae with bony fusion to maintain spinal stability. In the case of lumbar disc herniation in the elderly, in order to avoid recurrence and the lower functional requirements of the elderly, lumbar disc removal with bone graft fusion can be performed. The basic process is to clean up the discs, reveal the vertebral endplates, and place autogenous bone or cage implants between the vertebral interspaces, and then fixate them with pedicle pins. The main point is to fuse the upper and lower vertebrae together to maintain spinal stability. Lumbar herniation fusion is generally used for patients with severe lumbar disc herniation leading to spinal stenosis or cauda equina syndrome, and the surgery is difficult, so patients are advised to go to regular hospitals for treatment.
