3D imaging can improve pedicle screw precision: study


Research from New York City-based Hospital for Special Surgery found 3D imaging was better than 2D radiographs for confirming pedicle screw placement in spine surgery.

Three things to know:

1. Researchers studied data from 103 patients who had a spinal fusion from one surgeon between 2019 and 2022, according to a March 7 news release from HSS. Pedicle screw placement was analyzed with intraoperative BPR and 3D imaging.

2. Postoperative imaging found a "clinically significant" number of patients who had false-negative and false-positive screw placement readings on BPR. Screw positions on intraoperative 3D imaging was found to be more accurate.

3. The study is reportedly the first to compare difference in 3D imaging and biplanar radiography for pedicle screw placement, spine surgeon Darren Lebl, MD, said in the release.
