Lumbar disc herniation treatment enters the minimally invasive era The foraminoscopic technique gradually enlarges the intervertebral foramen through the lateral foraminal approach using a special reamer and corresponding medical instruments to completely remove any herniated or prolapsed fragments and degenerated inflammatory nucleus pulposus under endoscopic surveillance. It also allows for continuous irrigation of the lesion, repair of the fibrous annulus using radiofrequency electrodes, ablation of nerve sensitizing tissue, blocking of the annular nerve branches, and relief of the patient’s soft tissue pain with less trauma than the usual posterior approach surgery. Compared with other minimally invasive treatment, intervertebral foramoscopy technology has smaller trauma: only 6mm; easier anesthesia: local anesthesia; less bleeding: almost no bleeding; safer: endoscopic operation, clear vision, can effectively avoid the risk of misoperation; shorter operation time: 60-90 minutes; faster postoperative recovery: bed time of about 1 day, hospitalization time of 3-5 days; high surgical efficiency: the operation is performed in a few days. 5 days; high surgical efficiency: about 97.5%, no postoperative pain; lighter economic burden and other obvious advantages. Indications for treatment Persistent or recurrent pain radiating from the hip or lower limbs.
