The development of percutaneous accesses and full-endoscopic operations (endoscope, working channel, light source, monitor), all instruments are guided through the endoscope under direct control via access points smaller than 1 cm, Therefore, many procedures can be performed under local anesthesia. Depending on the localization of the Depending on the location of the herniated disc or stenosis, the access is either at the side (transforaminal) or in the center of the spine (interlateral). center of the spine (interlaminar). Using micro forceps and micro scissors, the herniated The herniated disc is removed using micro forceps and micro scissors while carefully protecting the nerves and spinal cord. If the spinal canal is narrowed, it is widened using appropriate micro-milling cutters and the nerves are freed. The advantages are a very good cosmetic result, less pain postoperatively, a low risk of infection and rapid mobility as well as a high degree of safety and effectiveness. safety and effectiveness.
