目的 :颈椎手术前方入路 ,以颈椎前外侧沟为标志 ,为避免损伤椎动脉、静脉提供形态学基础。方法 :观察 12 7套干燥颈椎标本的颈椎前外侧沟。解剖颈胸段脊柱标本 15例 ,观察头颈长肌及间距。结果 :①颈椎前外侧沟位于颈椎前外侧 ,沟中点深为 1.6～ 4.9mm。②两侧颈椎前外侧沟间距在 19.0～42 .7mm。③左右横突孔间距为 2 5 .9～ 44.7mm。④颈椎横突孔前壁厚为 1.5～ 3 .9mm。⑤头颈长肌位颈椎前方 ,大部分位于颈椎前外侧沟内。结论 :以颈椎前外侧沟为标志 ,两沟之间为颈椎手术前方入路安全区域。
OBJECTIVE: To approach the anterior approach of cervical spine surgery and to mark the anterolateral cervical groove. Morphology is provided to avoid damage of vertebral artery and vein. Methods: The anterior cervical dorsal groove of 12 7 dry cervical specimens was observed. Fifteen cases of cervical thoracic spine were dissected, and the long muscles of the neck and neck were observed. Results: ① Anterior cervical lateral sulcus is located in anterior cervical spine, ditch depth of 1.6 ~ 4.9mm. ② lateral anterolateral cervical ditch spacing 19.0 ~ 42 .7 mm. ③ left and right transverse hole spacing of 25.9 ~ 44.7mm. ④ cervical transverse foramen before the wall thickness of 1.5 ~ 3 .9 mm. ⑤ head and neck long position in front of the cervical spine, most of the anterior lateral groove in the cervical spine. Conclusion: Anterior cervical lateral sulcus is a symbol of the safety of the anterior approach of cervical spine surgery.
