目的研究胸椎横突与邻近骨性结构的解剖关系,探讨胸椎经横突-椎体螺钉固定术式的可行性、安全性及注意事项.方法正常成人胸椎干燥骨标本45具,解剖测量横突水平中线至椎弓根上、中、下缘的距离,横突前外侧被肋骨遮挡区的高度及横突水平中线对应于椎体的位置.结果 T1～ T10横突中线都在椎弓根上下缘平面范围内,T6～T7两者中线较接近,Tg、T10两者中线离的较远,T1～T8横突外侧完全或大部被肋骨遮挡,而T9、T10横突外侧被肋骨遮挡较少;横突水平中线对应椎体上1/3下部或中1/3.结论胸椎经横突-椎体固定安全可靠,有临床实用价值.

Objective To study the anatomic relationship between the thoracic transverse process and adjacent bony structures and its clinical significance for thoracic screw fixation.Methods The present anatomic measurement used 45 dry cadaveric specimens of the normal adult thoracic vertebrae.We measured the distances from the horizontal midline of the transverse process to the superior,middle and inferior margius of the pedicle,the height of the anterolateral transverse process sheltered by ribs,and the position at the horizontal midline of the transverse process corresponding to the vertebral body.Results The horizontal midlines margius of the transverse processes of T1 to T10 are localized in the plane ranging from the superior to the inferior margins of the pedicle.The midlines of the transverse process are closer at T6 and T7 while more apart at T9 and T10.From T1 to T8,the anterolateral transverse process is totally or mostly sheltered by ribs,but the shelter is much less at T9 and T10.The horizontal midline of the transverse process corresponds to the upper 1/3 or middle 1/3 of the vertebral body.Conclusion Thoracic screw fixation across the transverse process to the vertebral body is safe,reliable and feasible in clinic.
