What is Mazor X surgical robot? | Valenia Health Services

The Mazor X Stealth Edition, the latest model of the Mazor, is a robotic surgery system consisting of a workstation and a robotic arm.

Unlike its predecessors, includes an integrated optical camera that allows the robot to acquire images in real time and perform a volumetric evaluation of the surgical field to auto-detect its location and avoid collisions with other system components.


  • Surgery to correct scoliosis
  • Arthrodesis of the dorsal spine (degenerative, traumatic or tumor pathology)
  • Arthrodesis of the lumbar spine (degenerative, traumatic or tumor pathology)
  • Vertebral interbody fusion
  • Vertebral biopsy (tumor pathology)
  • Kyphoplasty (vertebal fractures)


Robotic surgery systems have shown obvious advantages in comparison with conventional surgery of the spine:

  • Improved precision in the placement of implants. Recent studies have confirmed that the system has a 98.7% precision rate of correct placement of screws (without deviation).
  • Minimizes exposure to ionizing radiation, both for the patient and for all the operating room personnel. The average time required to insert a screw is 3.6 minutes, which reduces both the duration of the surgery and the risk of infection, as well as reduced exposure to radiation.
  • Facilitates minimally invasive surgeries, which means a smaller surgical incision, and reduced loss of blood.
  • Reduced postoperative pain thanks to the use of the robotic arm that less muscle retraction needed to operate in deep tissue.
  • Contributes to a lower risk of infection thanks to a shorter time in surgery.
  • Reduced risk of infection in the adjacent segment according to recent studies.


The Mazor X robotic surgery system works as follows:

  • The surgeon plans the surgical path of the implants using the patient’s images (CT scan taken before or during surgery) at the Mazor X Stealth Edition work station.
  • The patient is placed on the operating table.
  • The robot is anchored to the table and to the patient.
  • The robotic arm records images of the patient. Mazor X features an innovative cross-modality image recording process, each vertebral body is independently registered. The robotic guidance system analyzes and pairs images from different modalities, such as matching a preoperative CT scan with intraoperative fluoroscopy or 3D surgical images, including images captured at different times and in different anatomical planes.
  • The software guides the robotic arm according the the plan established by the surgeon for the surgical field.
  • Placement of implants by the surgeon aided by the real-time neuronavigation system and guided by the robotic arm.
