A self-contained tubular drill guard was adapted for use in performing anterior cervical discectomies and interbody fusions. The use of this instrument eliminates steps, provides absolute safety against drilling too deeply, allows for adjustment in individual cases, provides for easy inspection of the trephine hole, permits electing the cephalocaudal angle of the drill, and gives a measurement of the ultimate depth of the trephine hole. In 171 consecutive operations only one neurological complication occurred, and total morbidity related to cervical surgery was 6% (7% morbidity was associated with surgery at the donor site). The data suggest that the technical modification herein advocated reduces the surgical complication rate.
一种独立的管状钻孔防护装置适用于颈椎前路椎间盘切除和椎间融合手术。使用该器械可省去一些步骤，提供防止钻孔过深的绝对安全保障，允许根据个别情况进行调整，便于检查环锯孔，可选择钻头的头尾角度，并能测量环锯孔的最终深度。在连续171例手术中仅发生1例神经并发症，与颈椎手术相关的总发病率为6%（7%的发病率与供体部位的手术有关）。数据表明，本文所倡导的技术改进降低了手术并发症发生率。
