After lumbar disc herniation by surgical internal fixation, the following side effects can occur: First, lumbar intervertebral fusion is usually performed after surgical internal fixation, which makes the adjacent lumbar vertebrae a unified whole and affects the small joints between lumbar vertebrae for flexion, extension and rotation activities, resulting in a reduced range of lumbar vertebral activities, and in serious cases, restricted lumbar vertebral activities can occur. Second, the internal fixation after lumbar spine surgery makes the lumbar spine stress concentrated to the adjacent vertebrae and intervertebral discs, which can lead to secondary lumbar disc herniation, compression of nerves, causing lumbar disc pain symptoms, and after lumbar spine internal fixation, the lumbar muscles atrophy, which can easily cause lumbar muscle strain pain, and at the same time can lead to lumbar weakness and inability to maintain standing or sitting posture for a long time.
