Robot-assisted Spinal Fusion

  • In 2007, Dr. Dennis P. Devito was the first in the U.S. to use the robot-assisted device on children with scoliosis.
  • He has an accuracy rate of 99.7%, compared to the 85-90% industry average. As of January, 2012, he placed a total of 1,815 screws with the assistance of the Mazor Renaissance robot.
  • Only ten Mazor Renaissance robots exist in the U.S.

Benefits of Robot-assisted Technology

  1. Increased precision
  2. Decreased complications
  3. Decreased radiation exposure from the more commonly used fluoroscopy
  4. Decreased OR time
  5. Decreased revision rates
  6. Better pre-operative planning

How Does it Work?

  1. Using a preoperative CT scan of the spine, the surgeon plans the surgery and evaluates the placement of pedicle screws. The surgical plan is then downloaded to a spine-assist computer work station.
  2. The spine-assist platform is clamped onto the patient’s spine. Two fluoroscopic images are taken to orient the spine-assist CT scan and operative plan to the patient’s anatomy.
  3. The surgeon designates the first vertebra and pedicle, and the spine assist moves into position. The arm adjusts to the predetermined angle of placement of the pedicle screw.
  4. Through the robot arm, the surgeon uses a drill to prepare the hole, probes it, and then inserts the pedicle screw based on the trajectory set by the robotic device.
  5. The screws anchor rods that hold the spine in place, allowing for proper fusion of the bones.
