Abstract
Hemostatic agents are often used in spine surgery to control excessive bleeding. Oxidized cellulose (OC) is a common hemostatic agent used for this purpose. We present a case of postoperative cauda equina syndrome caused by Surgicel (Johnson & Johnson, New Jersey, US). An emergent decompression led to complete recovery. All attempts should be made to remove OC before closure after hemostasis has been achieved.
