摘要
为了观察压迫桡神经的腱性结构及其有关解剖,共研究了40具成人及10具新生儿的100侧上肢。在80侧成人上肢中均可见到桡侧腕短伸肌纤维桥及旋后肌弓,有肱三头肌纤维桥的48侧(60%),肱桡肌纤维桥的34侧(42.5%)。在20侧新生儿上肢中,这些腱性结构尚未完全发育,仅少数桡侧腕短伸肌纤维桥起始部与旋后肌弓近侧缘可出现一些结缔组织。测量了桡管上、中、下三段的长度,观察了各段内桡神经的毗邻关系。桡神经的浅、深支分叉部位在髁间线以上的33侧(41.25%),髁间线以下者29侧(36.25%),平髁间线的18侧(22.5%)。熟悉这些解剖内容,有助于桡神经受压综合征的诊断与治疗。
100 upper extremities(40 adults,10 newborns)were dissected to study the tendi-nous structures which entrapped the radial nerve and anatomical relationships of the radial nerve.In 80 adult upper limbs,the fibrous bridge of the extensor carpi radialis brevis and arcade of supinator were all found,while the triceps brachii bridge and the brachioradialis bridge were present in 48 sides(60%)and 34 sides(42.5%)respectively.In 20 newborns upper limbs,these tendinous structures were not fully developed,only a few connective tissues appeared in the origin of the extensor carpi radialis brevis and at the proximal margin of the arcade of supinators.The lengths of the upper,middle and inferior sections of the radial canal were measured.The anatomy of the radial nerve in three sections of the radial canal were also observed.The level at which the radial nerve divided into the superdicial and deep branches occurred above the intercondylar line in 33 sides(41.25%),below it in 29 sides(36.25%),and at the intercondylar line in 18 sides(22.5%).Understanding these tendinous structures is helpful in diagnosis and treatment of the radial nerve compression syndrome.
