Robotic spine surgery

Specialty of Neurosurgery

Vertebral fixation consists of the placement of screws in the vertebrae to anchor them, either at the cervical, dorsal or lumbar level. This implant surgery relies on GPS navigation, which enables a high percentage of success, of 97.6%, in fact. Additionally, GPS navigation avoids the risks of classical techniques, such as nerve injuries, and makes secondary procedures due to poor screw positioning unnecessary. To perform this surgery a computer and optical cameras are used in conjunction with images of a preoperative CT scan and those of an x-ray made in the patient's actual surgical position, fusing (converting) them all into real-virtual 3D images. Through a special instrument, the surgeon can visualize the trajectory of the screws as a live feed.

In addition to navigation in this type of surgery, The nerves to the vertebral segment that is involved are monitored through a computer, providing an electrical record of the muscles innervated by said nerves. In the case of possible irritation or nerve damage, the computer warns the surgeon by an abnormal wave discharge and an acoustic signal, which allows the trajectory of a screw to be altered, thereby avoiding injuries.
