LAS VEGAS, March 7, 2023 /PRNewswire/ — A examine at Hospital for Particular Surgical procedure (HSS) discovered that intraoperative three-dimensional (3D) imaging was superior to two-dimensional radiographs in confirming the accuracy of pedicle screw placement throughout spine surgical procedure. The analysis was offered immediately on the American Academy of Orthopaedic Surgeons (AAOS) Annual Assembly in Las Vegas.
Many spinal surgical procedures require using implants referred to as pedicle screws to stabilize the spine. Exact positioning of those screws is vital for a profitable final result. “Two-dimensional biplanar radiographs [BPR] have been the gold normal to verify pedicle screw placement in spine fusion surgical procedure for a few years. Nonetheless, when using BPR, there’s the potential {that a} two-dimensional picture alone won’t correctly exhibit the profitable placement of a screw,” stated Darren Lebl, MD, a spine surgeon at HSS and principal investigator of the examine. “As a substitute, three-dimensional intraoperative imaging methods at the moment are out there, providing improved visualization.”
Dr. Lebl and colleagues got down to examine the accuracy of BPR versus 3D imaging when assessing intraoperative pedicle screw placement. “Our examine is the primary to check the variations in intraoperative biplanar radiography and 3D imaging for pedicle screw accuracy in thoracic and lumbar instances utilizing robotic expertise,” Dr. Lebl famous.
Investigators analyzed information from 103 sufferers who underwent spinal fusion by a single surgeon from 2019 to 2022. Pedicle screw placement was assessed with each intraoperative BPR and 3D imaging in every case.
“CT scans taken after surgical procedure have been in comparison with the findings of intraoperative BPR and 3D imaging to detect both false-positive or false-negative readings,” defined Fedan Avrumova, BS, an HSS medical analysis coordinator who offered the examine on the AAOS assembly. “False constructive findings are situations when BPR imaging suggests the screw was not in an appropriate place, whereas in reality a extra superior 3D picture (intraoperative 3D scan or postoperative CT scan) confirmed the screw to be in an appropriate place. Conversely, a false unfavourable occasion was when a BPR picture led one to imagine or appeared as if the screw was in an appropriate place, when in reality a extra superior 3D picture or post-operative CT scan confirmed that it was in reality not acceptable.”
Postoperative CT imaging revealed a clinically important variety of sufferers who had false-negative and false-positive screw placement readings on BPR. Nonetheless, screw place proven on intraoperative 3D imaging was discovered to be far more correct, Avrumova added.
“Primarily based on our examine, BPR imaging could lead one to assume a screw is suitable when in reality it’s not, and in addition could miss many screws that aren’t in reality acceptable. In our examine, it was roughly one p.c of instances the place this occurred. Nonetheless, for surgeons and facilities that implant a whole bunch and hundreds of screws per 12 months, that is going to end in a major medical affect for many individuals,” Dr. Lebl famous. “Even one misplaced screw can have a major affect for a affected person, a surgeon, and a hospital system. Due to this fact, based mostly on these findings, we propose that for intraoperative affirmation of screw place 3D imaging could quickly characterize a brand new normal of care.”
