What surgical procedure may be required in severe cases of lumbar instability to eliminate abnormal vertebral motion?
Answer
Surgical fusion
In cases of severe lumbar instability where conservative treatments such as physical therapy, bracing, and muscle strengthening fail to restore function, more invasive measures are considered. Surgical fusion is a procedure where the problematic vertebral segments are permanently joined together. The primary goal of this intervention is to stop the excessive, pathological motion between the vertebrae that is causing pain or neurological symptoms. By eliminating this abnormal movement, the surgeon effectively removes the instability at that specific spinal segment, providing a stable, albeit less mobile, structural outcome.
