摘　　要：目的:探讨桡神经深支自发断裂的解剖学因素,为临床诊断该病及选择手术入路及方法提供理论依据。方法:成人上肢标本16侧,沿臂部桡神经走行进行大体及显微解剖。结果:(1)18.9%的桡神经主干及深、浅支存在"翻转现象";(2)桡侧返血管与桡神经深支存在3种毗邻关系,可对其造成卡压、夹持作用;(3)37.5%的桡神经深支在进入Frohse弓近端(3.1±1.2)cm处表面横跨一异常纤维束带;(4)桡侧腕短伸肌腱性部分与Frohse弓存在3种位置关系,可在不同平面对神经产生压迫作用。结论:(1)桡神经"翻转现象"是桡神经深支自发断裂的形态学基础及潜在易发因素;(2)而桡侧返动脉、异常纤维束带、桡侧腕短伸肌腱性结构及Frohse弓是其发病的解剖学基础(继发因素)。Objective： To study anatomic factors concerning with the spontaneous disruption of the deep branch of radial nerve, and provide basis for clinical diagnosis, treatment and the selection of operation approach. Methods： 16 adult fresh cadaverous upper extremity specimens were included in this study, which were dissected following the course of radial nerve by gross anatomy and microdissection. Results： （1） In 18.9 % specimens, the phenomenon of ＂turnover＂ presented for the trunk, deep and superficial branches of radial nerve; （2） Three relationship concerned with the recurrent branch of radial arteries and the deep branches of radial nerve,which might be the reasons of the crush and clamp on radial nerve; （3） In 37.5% specimens, a abnormal fiber bundle acrossed the deep branch of radial nerve before it left the proximal end of Frohse arcade about 3.1 ± 1.2cm; （4） 3 types of relationships between the origin of the ECRB and the arcade of Frohse caused nerve oppression at the different planes. Conclusions： （1） The phenomenon of ＂turuover＂ in the radial nerve is the morphologic basis and latent etiological factor of the spontaneous disruption of the deep branch of radial nerve; （2） The recurrent branch of radial arteries, abnormal fiber bundles, the origin of the tendon structures of the ECRB and the arcade of Frohse are anatomic factors of spontaneous disruption.
