Intervertebral foraminoscopy Intervertebral foraminoscopy is the latest type of spinal endoscope, compared with the previous posterior discoscopy, the operating channel is thinner, no need to open the vertebral plate, less trauma, less than 7mm skin incision, less than 20ml of bleeding, and only 1 stitch after surgery. It is the least traumatic and most effective minimally invasive treatment for herniated disc among similar surgeries. It can remove the herniated nucleus pulposus, repair the ruptured annulus fibrosus, and enlarge the intervertebral foramen (nerve root outlet), thus eliminating nerve root inflammation and disc compression with minimal trauma and maximizing the preservation of disc function, while hardly affecting the stability of the spine. Since the introduction of foraminoscopic technology in our department, we have successfully performed foraminoscopic disc nucleus pulposus removal and fibrous ring repair for many patients with lumbar disc herniation. The vast majority of patients have immediate postoperative symptomatic relief and can be discharged from the hospital within three days after surgery. The procedure is particularly effective in patients with huge disc herniation, prolapsed or free discs, and has enabled many patients to avoid open surgery. Surgical features Trauma size: operated under visualization, minimally invasive, only 6mm No need to open the vertebral plate, wound about 7mm Surgical time: short About 60 minutes Safety: safer, clear vision, can effectively avoid the risk of misoperation Efficacy rate: > 95% Bleeding volume: about 20ml Pain: slight slight pain after surgery, can be relieved by oral painkillers if necessary Anesthesia method: local anesthesia Bed time: about 1 day Length of hospitalization: three days after surgery Discharge from hospital Postoperative care: easier, basically self-care after 24 hours Recurrence rate: less than 3% Recovery time: quicker, 3-6 weeks
