摘要：

背景：为探寻除椎弓根外胸椎后路安全的螺钉进钉途径，现在国内外许多学者们对胸椎肋横突结合区的解剖结构进行了大量研究，结论尚不一致。

目的：进行成人肋横突沟的解剖学与放射学测量，以探寻椎弓根外胸椎后路螺钉置入安全途径。
方法：取8具成人防腐胸椎标本及相连的一段长5.0-6.0 cm的肋骨，保留肋间软组织和壁胸膜，去除其他软组织。对标本进行CT扫描，并进行三维重建，测量肋横突沟角度，对标本进行解剖学分析，测量肋横突上缘距离和肋横突下缘距离。

结果与结论：成人肋横突结合区内存在1肋横突沟，直达椎体。肋骨上缘至横突上缘距离和肋骨下缘至横突下缘距离在第6-10胸椎节段最大，和其他节段比较差异有显著性意义(P < 0.05)，肋横突沟在第6-10胸椎节段最明显。结果证实，成人肋横突沟可直达椎体，为椎弓根外胸椎后路安全螺钉置入途径提供了新的思路。

Abstract:

BACKGROUND: Many present scholars do a large number of researches on anatomical structure in the thoracic costotransverse binding region so as to seek a safe pathway of screw entrance besides posterior thoracic approach outside pedicle, but their conclusions are controversial.

OBJECTIVE: To measure the anatomical and radiological structures of costotransverse groove and to explore the safe pathway of screw implantation via posterior thoracic vertebra outside pedicle of vertebral arch.
METHODS: Eight embalmed adult cadaveric thoracic spines were harvested with the medial 5.0-6.0 cm of rib. Intercostal soft issue and parietal pleura were left intact. All nonstructural soft issue was removed. Specimens were scanned with CT, and three-dimensional reconstruction was performed. The angles of the costotransverse groove were obtained. Anatomical analysis was performed in specimens. The distance from the superior limit of the rib superiorly to the superior limit of adjacent transverse process and the distance from the inferior limit of the rib inferiorly to the inferior limit of adjacent transverse process were measured.

RESULTS AND CONCLUSION: There exists a costotransverse groove between rib and transverse process. Both distance from the superior limit of the rib superiorly to the superior limit of adjacent transverse process and the distance from the inferior limit of the rib inferiorly to the inferior limit of adjacent transverse process of T6-10 were significantly larger than other levels (P < 0.05). The costotransverse groove was most obvious at T6-10 segments. Results verified that adult costotransverse groove directed to vertebra, and provided a new idea for the pathway of screw implantation via posterior thoracic vertebra outside pedicle.
