AbstractObtaining intraoperative images of the spine in the obese patient and at the cervicothoracic junction have historically been technically difficult due to variable penetration and x-ray scatter. This is particularly true for spinal deformity cases, where clear visualization of the end plates is needed to determine if functional alignment has been restored to the spine. The novel "2D long film" functionality for the Medtronic O-arm is capable of capturing the x-ray backscatter, producing enhanced intraoperative images. Furthermore, images can be obtained along the gantry translation of the O-arm and combined into a single long image, optimizing the workflow of surgeons who use the O-arm for intraoperative navigation. The purpose of this report is to highlight 2 example spinal deformity cases that underscore the utility of this imaging technology. In both cases, standard intraoperative fluoroscopy visualization was unacceptable, so 2D long film images were obtained to assess postcorrection spinal alignment.Copyright © 2021 Elsevier Inc.
