摘要
目的了解斜角肌间隙内臂丛下干与邻近组织结构及胸１神经干与第１肋的关系，为临床诊治臂丛下干卡压症提供解剖学依据。②方法在２１具４２侧成人标本上观测臂丛下干与邻近结构的位置关系。③结果在４２侧标本的斜角肌间隙内，有３３侧在前斜角肌的后内侧存在孤立的肌束，臂丛下干分别从其前下方（２３侧）或后上方（１０侧）通过；组成臂丛下干的胸１神经干在斜越第１肋前内侧面时部分穿行于骨纤维管内。④结论该肌束的压迫或拱抬均可成为臂丛下干受压的因素之一；组成臂丛下干的胸１神经干在越过第１肋时易受压迫。
\ Objective \ To learn about the inferior trunk of brachial plexus and its relationship with its
neighbour structure in the scalene fissure as well as the connection between T1 nerve root and
the first rib in order to provide anatomic proofs for diagnosis and treatment of brachial
plexus compression syndrome.\ Methods \ Anatomical study was done on 42 sides of 21
adult embalmed cadavers. The locational relationship between the inferior trunk of brachial
plexus and its neighbour structure was observed and measured.\ Results \ In the scalene
fissure,there was an isolated muscle on the posteromedial of scalene anterior and it was
found in 33 sides of the cadavers. The inferior trunk of brachial plexus went through its
interoinferior side (23 sides) or its posterosuperior side (10 sides) respectively; T1 nerve root,
which formed the inferior trunk of brachial plexus, went partly through inside a tube of bone
and fibre when crossing the anteromedial side of the first rib.\ Conclusion \ The
compression or lifting of the isolated muscle might be one of the causes of the inferior trunk
compression of brachial plexus; T1 nerve root was easy to be compressed when crossing the
first rib.\;
