摘要
目的:通过对胸、腰椎上关节突棘形态的观测,为临床提供解剖学资料。方法:选用35例成人、2例儿童的完整干燥脊柱标本及5例胎儿脊柱湿标本,观察上关节突棘,用游标卡尺进行相关测量。结果:成人的颈椎、T1和L5及儿童和胎儿的全部脊柱标本上未观测到上关节突棘的存在,成人其余的胸椎和腰椎上均观察到上关节突棘,而且上关节突棘多出现在下胸椎和L1,随着胸椎序数的增加上关节突棘的出现率有增加的趋势;随着腰椎序数的增加,上关节突棘的出现率有减少的趋势。结论:上关节突棘是成人胸、腰椎的骨性结构,有必要对其予以命名;其参与椎管和椎间孔的构成,可造成相应结构受压。
Objective： To investigate the lamina on superior articular process in the thoracic and lumbar vertebrae and provide anatomic data for the clinic. Methods： The lamina on superior articular process in the thoracic and lumbar vertebrae were measured, using caliper, in 35 sets of dry adult spines, 2 sets of dry child spines and 5 sets of fetal spines. Results： No lamina on superior articular process were found on fetal and child spines, as well the cervical, T1 and L5 vertebrae of adult spines. However, the lamina were found on other thoracic and lumbar vertebrae in adult spines. From T1 to T12 vertebrae, the occurrence rate of the lamina on superior articular process increased, whereas, the occurrence rate decreased from L1 to L5. Conclusions： The lamina on superior articular process is a bony structure of adult thoracic and lumbar vertebrae .It may compress the nerve roots, and it is necessary to name it.
