Percutaneous internal spinal nail fixation, or “minimally invasive surgery” as it is known in everyday life, is an advanced surgical procedure for the treatment of spinal disorders such as lumbar spondylolisthesis, lumbar instability and lumbar fractures. Compared with traditional open surgery, it has incomparable advantages: small intraoperative incision, less trauma and bleeding, and no extensive incision of soft tissues such as muscles and ligaments, thus avoiding delayed spinal instability caused by excessive stripping of muscles and soft tissues. Due to the small surgical trauma, the patient recovers quickly after surgery and can get out of bed early, which provides favorable conditions for functional exercise and recovery of patients with lumbar spondylolisthesis after surgery.
