BackgroundAnterior cervical surgery is routinely performed using fluoroscopy. Visualizing the lower cervical levels can be challenging, particularly in obese, muscular, and broad-shouldered patients. We found that grabbing both feet of the patient at the level of the metatarsals and cranially pushing the feet, creating dorsiflexion at the ankle joints, seems to increase the number of fluoroscopically visualized cervical levels. We aimed to measure the average change in fluoroscopically visualized levels when performing this maneuver.MethodsIn 10 consecutive patients undergoing an anterior cervical discectomy and fusion procedure, we counted the number of fluoroscopically visualized cervical levels. Visible cervical levels in lateral fluoroscopic cervical images that were taken with and without the execution of the aforementioned maneuver were counted by 2 blinded observers.ResultsPerforming this maneuver added on average almost 1 vertebral body height to the fluoroscopic image. The additional number of fluoroscopically visible cervical levels was significantly higher in patients <50 years old but was not affected by sex or body mass index.ConclusionsWe propose a simple, convenient, and effective technique to increase the number of visualized cervical levels on lateral cervical fluoroscopy. This maneuver may have some advantages compared with other commonly used techniques.Copyright © 2016 Elsevier Inc. All rights reserved.
