寰椎横韧带结节的形态学资料对颈髓损伤的应用意义

Applied significance of morphological data of transverse ligament tubercles of atlas in spinal cord injury

目的:为寰椎横韧带损伤的诊断和治疗提供解剖学资料。方法:用游标卡尺测量了51例寰椎,确定寰椎横韧带结节与其周围骨性结构间距离的正常值。结果:在侧块内侧缘51例寰椎双侧均存在单一的结节,供寰椎横韧带附着,结节表面光滑。横韧带结节间距离是(16.1±1.8)mm;两侧结节与齿突关节面之间的夹角是(93.7±9.8)°。总体看来,各测量值是恒定的。结论:寰椎横韧带结节的形态学资料有助于横韧带损伤的诊断和治疗。

AIM:To provide anatomical data of transverse ligament tubercles of the atlas for diagnosis and surgical procedures in transverse ligament injury. METHODS:Totally 51 dried atlas specimens were observed and measured with caliper to get the normal values of the distances between the transverse ligament tubercles and nearby osseous structures. RESULTS:In the medial margin of the lateral mass of all atlas specimens,single tubercles existed bilaterally for the attachment of the transverse ligament,and these tubercles exhibited smooth distal surfaces.The intertubercular distance was (16.1±1.8) mm,and the angle between both tubercles and the dental facet was (93.7±9.8)°.The measurements were constant on the whole. CONCLUSION:The morphological data of the transverse ligament tubercles are helpful to the diagnosis and surgical procedures of transverse ligament injuries.
