Although communications between branches and cords of the brachial plexus have been extensively published, there is a scarcity of reports concerning radial and ulnar nerve (RN-UN) communication in the arm. The current study aims to demonstrate the incidence, topography, and length of communicating branches between RN and UN. Any additional coexisted variations were also recorded.
Two hundred and sixty-six upper limbs collected from one hundred and thirty-three (81 males and 52 females) Greek cadavers were dissected.
Three out of one hundred and thirty-three cadavers, accounting for an incidence of up to 2.3%, were found to have an atypical communicating branch originating at a high humeral level from RN towards UN. In two cadavers, communicating branches were detected on the left side and in one cadaver bilaterally.
The study of atypical communications between RN and UN attracts great attention for its clinical importance, mainly in cases of peripheral neuropathies with diagnostic dilemma or upper limb nerve injury producing an otherwise unexpected symptomatology due to the aberrant nerve supply. Familiarity with these variations is crucial in avoiding misdiagnosis and preserving valuable communicating branches, thus achieving an uneventful outcome in cases of upper limb nerve injury repair.
尽管臂丛神经分支与束之间的交通已被广泛报道，但关于臂部桡神经与尺神经（RN - UN）交通的报道却很少。本研究旨在阐明桡神经与尺神经之间交通支的发生率、位置及长度。同时记录任何额外并存的变异情况。
解剖了从133具（81例男性和52例女性）希腊尸体上采集的266条上肢。
在133具尸体中，有3具发现存在非典型交通支，发生率高达2.3%，该交通支起自肱骨较高平面，从桡神经走向尺神经。其中2具尸体的交通支在左侧被检测到，1具尸体双侧均有。
桡神经与尺神经之间非典型交通的研究因其临床重要性而备受关注，主要体现在周围神经病变诊断困难或上肢神经损伤因异常神经供应导致意外症状的病例中。熟悉这些变异对于避免误诊和保留有价值的交通支至关重要，从而在上肢神经损伤修复病例中实现良好的预后。
