case_images: American Spinal Injury Association impairment scale (Fig. 1). An attempt to perform closed reduction with halo crown traction under mild sedation immediately after transfer to the hospital was unsuccessful.
case_images: a, b) Schematic illustration of the posterior percutaneous reduction with an elevator. c) Fluoroscopic image after percutaneous reduction with an elevator. d) Radiograph after reduction showing 18 -kyphosis and a dilated interspinous space at C4-C5.

case_images: An elevator was inserted into the locked facet percutaneously through a small incision above the facet with fluoroscopic assistance, and reduction was achieved by lever action without complications (Fig. 2).
case_images: Anteroposterior (a) and lateral (b) radiographs 3 months after ACDF showing complete bony union and 4 -lordosis.
