Title: Applied anatomy of anterior decompression and internal vertebral venous plexus
Abstract: Objective:To provide anatomic profile of hemorrhagic internal vertebral venous plexus in the surgical intervention and verify anatomic marks for safe anterior cervical decompression.Methods:6 fresh specimens and 12 adult preserved cadavers of craniocervical region were dissected layer by layer with microsurgical technique.Anatomic parameters,concerning with internal vertebral venous plexus,transverse foramen,uncinate process and vertebrae were measured.Results:In C3~C7 vertebrae,the distance were(5.25±0.85)mm between medial border of transverse formen and uncinate process.The distance between bilateral internal vertebral venous plexus increased from(11.13±0.20)mm in C3 to(14.98±0.27)mm in C7,and between bilateral anterior feet of uncinate increased from(14.6±1.03)mm in C3 to(21.51±1.91)mm in C7,and anterposterior diameter of uncinate process was about 11 mm.Conclusions:Bilateral anterior feet of uncinate process can be anatomically marked as lateral borders of safe anterior decompression of the lower cervical vertebrae,and of acting out the bilateral veins.
