這篇報告敘述一個新的頸椎骨內鋼釘固定技術，及二十七位行頸椎椎間盤切除及椎體間融合術之病患以此法固定經一年以上追蹤的結果。其中沒有神經併發症，沒有鋼釘移位及斷裂發生，所有的移植骨均得到融合，良好的手術中的放射線導引放置骨內鋼釘是非常需要的。這個方法提供給脊椎外科醫生另一種固定頸椎骨移植的有效方法。100%的骨融合率及避免了目前所用的頸椎前內固定系統所引起的併發症是這個方法最大的好處。

This article describes a new technique of intraosseous screw fixation of cervical spine, as well as a retrospective review of 27 patients who had anterior cervical interbody fusion after discectomy and fixation with one intraosseous Herbert screw, with a minimum follw-up of 1 year. The study included 19 male and 8 female patients. There were no neurologic complications at final follow-up evaluation. All patients had radiographic evidence of fusion.No screw breakage, back-out or dislodgement occurred. Optimal intraoperative radiographic evaluation for accurate intraosseous screw placement is recommended. The use of intraosseous screw fixation is a useful addition to the armamentarium of the spine surgeon when fixation of anterior cervical graft after discectomy is required. One hundred percent rate of union and avoidance of complications related to the currently used anterior fixation systems are the major advantages of this method.
