In order to meet the demand for minimally invasive treatment of spinal disorders, the department currently carries out various minimally invasive treatment modalities such as plasma radiofrequency treatment for disc herniation, ozone treatment and foraminoscopic treatment. Among them, intervertebral foraminoscopy technology was developed by Hoogland Spine Products GmbH in Germany in 2007 and started to be applied in China in 2011, which is the most advanced, safe, economical and minimally invasive treatment in the world. The intervertebral foraminoscope provides a variety of surgical access options such as posterior lateral laminae and internal/external foramina, and removes the diseased disc nucleus pulposus tissue under direct vision. The superficial incision is only 7.5mm, and the operation is non-interfering with the spinal canal and nerve roots, does not bite off the vertebral plate, does not destroy the paravertebral muscles and ligaments, and has no effect on the stability of the spine, which has many advantages such as low surgical risk, wide indications, fast recovery and high satisfaction, and is currently recognized as the “gold standard” and “ultimate treatment” for minimally invasive treatment of herniated discs. The “ultimate therapy”.
