  • VERTEBRIS lumbar
    The VERTEBRIS lumbar instrument set is designed for full-endoscopic decompression of the lumbar and thoracic spine....

  • Trans-/ extraforaminal technique

    The trans- or extraforaminal technique uses the intervertebral foramen as access to the pathology. The access to the intervertebral disk through the intervertebral foramen (transforaminal) or pedicle (extraforaminal) is placed under X-ray control with a puncture cannula. After dilation and insertion of the working sleeve, further surgery is performed through the diskoscopes under continuous irrigation with high-resolution endoscopic imaging.

    Precision instruments such as forceps, punches, electrodes and burrs with a special design enable the surgeon to perform the surgery effectively and accurately.

    Interlaminar technique

    In interlaminar surgery, the access to the spinal canal is done via the posterior interlaminar window. The dilator is guided directly to the flavum ligament with a dilator without prior puncture. After placing the working sleeve over the dilator, the operation is performed through the high-resolution 4K diskoscope under continuous irrigation. The functionality of the components of the access system and the instruments are precisely coordinated and allow to pass through the ligamentum flavum and the nerve root  with minimal traumatization.

    With special manual instruments and a variety of high-speed burrs available, herniated discs can be effectively removed and bone parts of spinal stenoses can be resected under a full-endoscopic view.

  • VERTEBRIS stenosis
    The Central Stenosis VERTEBRIS instrument set represents a true milestone of innovation and advancement in spine endoscopy....

  • Ipsilateral decompression on one side

    After the access has been created, the bony structures are exposed. It may be helpful to start decompression at the caudal end of the descending facet. Depending on the pathology, decompression is then commenced with resection of parts of the medial descending facet, the cranial and caudal lamina, and the ligamentum flavum. The extent of decompression generally continues cranially at least until the tip of the ascending facet and caudally to half of the pedicle. The medial portions of the ascending facet and the ligamentum flavum are then resected until sufficient decompression of the neural structures can be clearly seen - cranially, caudally and laterally. In the case of a central stenosis, the ligamentum flavum generally needs to be resected medially to the midline. Finally, it may be necessary to remove protruding annulus parts and osteophytes in the ventral epidural space

    Contralateral decompression in over-the-top technique

    If bilateral symptoms occur with a central stenosis, a unilateral approach is carried out with "over-the-top" access using the undercutting technique to the opposite side. For this purpose, bone in the ventral area of the spinous process is resected until the contralateral side can be accessed dorsally up to the dura of the spinal cord. If possible, the ligamentum flavum is initially left in place to protect the dura and bony decompression is again carried out by laminotomy and partial facetectomy. The ligamentum flavum is then completely resected. Finally, the contralateral recess needs to be extended. The decompression is completed when the dura and the spinal nerves have been clearly decompressed.

  • VERTEBRIS cervical
    VERTEBRIS cervical are designed specifically for the anatomical requirements of an anterior and a posterior approach....

  • Posterior technique

    The posterior cervical instrument system includes a specially designed instrument set and a well defined, repeatable, technique for the posterior approach to the cervical spinal canal.  The instrumentation includes bone burrs that give the surgeon the ability to perform bone resection under visualization in the area of the foramen, the uncinate process or the posterior edge of the spinal column.

    Since the cervical spinal cord cannot be manipulated, the posterior approach is limited to herniations where the main portion of the herniation is localized laterally to the lateral edge of the spinal cord.  Under the proper indications, the posterior cervical system provides an excellent endoscopic alternative to open techniques.

    Anterior technique

    Herniations presenting with their main portion located medially to the lateral edge of the spinal cord are regarded as indications for an anterior approach to the cervical spine. The anterior cervical system includes a custom designed dilator-sleeve system which interfaces with a unique cervical endoscope, as well as specialized instrumentation, to provided excellent access to the posterior disc area.  The full-endoscopic anterior cervical approach provides a significantly less traumatic alternative to conventional surgery.

  • PERCULINE nucleo
    Reusable universal instrument set for percutaneous nucleoplasty using 4 MHz radiofrequency current application in interventional therapeutic pain interventions on the lumbar spine....

  • Lumbar Disk Nucleoplasty 
    While rongeurs are used to remove the material directly from the vertebral disk, the application of radiofrequency current with bipolar TipControl instruments acts on the one hand to reinforce the tissue of the vertebral disk (volume reduction) and on the other hand to destroy the small nerve fibers at the fiber ring of the vertebral disk. The spinal nerves are indirectly decompressed and the destruction of the nerve fibers prevents conduction of pain information to the brain.
