ObjectiveCervical and lumbar disk herniations are the most frequently carried out procedures in spinal surgery. Often, a few snapshots during the procedure are necessary to validate the level or to position the implant. The objective of this study is to quantitatively estimate the radiation received by a spine surgeon and patient during a low-dose radiation procedure.MethodsWe conducted a prospective multicenter study in France from November 2014 to April 2015. Four spine centers were monitored for radiation received by surgeons during interventions for lumbar disk herniation and cervical disk herniation.ResultsA total of 134 patients were included. For lumbar disk herniation, the average exposure for the surgeon was 0.584 μSv on the chest, 5.291 μSv on the lens, and 9.295 μSv on the hands per procedure. For these procedures, the dose area product (DAP) was 94.2 ± 198.4 cGy·cm(2), and the fluoroscopic time was 10.2 ± 16.9 seconds. For a herniated cervical disk, the average exposure for the surgeon was 0.122 μSv on the chest, 3.106 μSv on the lens, and 7.143 μSv on the hands per procedure. For these procedures, the DAP was 35.7 ± 72.1 cGy·cm(2), and the fluoroscopic time was 19.7 ± 13.7 seconds.ConclusionsExposure to x-rays for surgeons and patients during surgery for lumbar disk herniation is higher than during surgery for cervical herniation disk. Our results show that radiation exposure to the spine surgeon is still far below the annual dose limits.Copyright © 2016 Elsevier Inc. All rights reserved.
