Pedicle screw fixation is a popular method of fixation of the spine. Placement of screw and prevention of injury are surgeon dependent. We describe an easily made drill sleeve and depth gauge to assist in the preparation of the vertebral pedicle for pedicle screw application. Use of this device will help prevent soft tissue injury and overpenetration of the drill in the vertebral body.
椎弓根螺钉固定是一种常用的脊柱固定方法。螺钉的置入和损伤的预防取决于外科医生。我们描述了一种易于制作的钻套和深度测量仪，以辅助在应用椎弓根螺钉时准备椎弓根。使用该装置将有助于防止软组织损伤和钻头过度穿入椎体。
