Use of computer navigation and robotics in adult spinal deformity

Abstract

Recent years have seen significant advancements in the implementation of computer-assisted surgery in spine. Enabling technologies like robots and navigation have been refined to compliment the field's shift towards minimally invasive techniques and to fit more seamlessly into the existing workflow. Robotic-surgery and navigation in deformity can be particularly helpful in cases where the severe curves of the spinal column or the abnormal pedicle anatomy make pedicle screw placement challenging with the use of traditional anatomic landmarks. Furthermore, the ability to pre-plan patient specific rods has opened the door for greater precision in rod contouring. Drawbacks of robotic-assisted surgery include the steep upfront cost, the need for additional staff and training and the lack of tactile feedback. This review will discuss the current state of navigation and robotics, with a specific focus on their applications to deformity surgery.
