Robot-assisted Scoliosis Surgery
- 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
- Increased precision
- Decreased complications
- Decreased radiation exposure from the more commonly used fluoroscopy
- Decreased OR time
- Decreased revision rates
- Better pre-operative planning
How Does it Work?
- 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.
- 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.
- 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.
- 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.
- The screws anchor rods that hold the spine in place, allowing for proper fusion of the bones.
