F E A T U R E findings , we suggest that for intraoperative confirmation of screw position 3D imaging may soon represent a new standard of care ."
In keeping with this , an orthopaedic surgeon at HSS has performed the first augmented reality-guided spine surgery in New York State . We now hear more about this technology , as well as 3D imaging and CT scans , is helping spinal advancements . . . .
Frank Cammisa , MD , Chief Emeritus of HSS Spine , performed a successful spinal decompression and fusion on a 28-yearold male patient with the first augmented reality ( AR ) system cleared by the FDA for navigation in spine surgery .
Augmented reality refers to digital information that is superimposed on a user ' s view of the physical environment , providing images that can ' t be seen with the naked eye .
AR navigation in spine surgery superimposes 3D images of a patient ' s anatomy onto the surgeon ' s view of the operative field . Critical elements include a preoperative CT scan of the patient ' s spine – which is used to plan and perform the surgery – and an augmented reality headset worn during the procedure .
The system Dr . Cammisa uses consists of a near-eye-display headset and the elements of a traditional navigation system . During surgery , it accurately determines the position of surgical instruments in real-time and superimposes them on the patient ' s CT data . It has been likened to giving surgeons ‘ X-ray vision ’, enabling them to see structures underneath the skin .
" The technology allows us to visualise the patient ' s 3D spinal anatomy during surgery to accurately guide instruments and place surgical implants , such as pedicle screws while looking directly at the patient rather than at a separate computer screen ," Dr . Cammisa added .
" Improved control and visualisation of the patient ' s anatomy and critical structures can lead to a more precise , efficient surgery and can enhance safety ."
He notes that the technology allows for highly personalised surgeries that can be used for most spinal procedures requiring the use of implants . People with degenerative disc disease , spinal stenosis and spinal deformities may be candidates .
Dr . Cammisa notes that as more surgeries are performed with the augmented reality system , patient follow-up and data collection will enable HSS researchers to compare AR to other technologies used in spine surgery to evaluate outcomes . �
