作者于50具尸体解剖观察,发现桡神经浅、深支分叉点高于肱骨外上髁平面;旋后肌弓有襻型、环型之分,多为半肌半腱性(腱性之Frohse弓仅占18％);弓的浅面有桡侧腕短伸肌弓(几乎全属腱性)覆盖;骨间后神经经外侧半弓的深方穿入。被动旋后时,骨间后神经为桡侧腕短伸肌弓所约束,旋前时松解;为旋后肌弓压迫者为数较少。桡神经的浅支发三种肌支,主要是桡侧腕短伸肌支,也可以发支支配旋后肌;25％人体的一侧桡侧腕短伸肌只受桡神经浅支支配。桡神经浅支并不是一完全的感觉支。骨间后神经只发两种肌支,大部分是桡侧腕短伸肌支。作者据解剖所见,结合部分临床文献,认为桡侧管综合征用名不够贴切,建议命名为“肘桡侧弓综合征”。 Autopsy observation of the 50 corpses showed that the superficial and radial branches of the radial nerve were higher than the lateral epicondyle of the humerus. Frohse bow accounted for only 18%); shallow superficial wrist radial short wrist extensor (almost all tendon) coverage; posterior interosseous nerve through the lateral half-bow deep penetration. After passive rotation, the posterior interosseous nerve is constrained by the radial wrist short extensor arch, pronation when the release; after the rotation of the armpit oppression less. Radial nerve shallow branch of the three muscular branches, mainly the radial wrist short extensor branch, also can support the dominance of the spinoparoid; 25% of the human body on one side of the radial wrist short extensor only by the radial nerve superficial branches dominated. Superficial radial nerve is not a complete sensory branch. After the interosseous nerve only made two kinds of muscular branch, most of the radial wrist short extensor branch. According to anatomical findings, combined with some clinical literature, that the name of the radial tube syndrome is not appropriate, it is recommended that the name “elbow radial bow syndrome.”
