在尸体研究中报告了肱三头肌的其他滑动。我们报告的情况下，一个48岁的男子没有历史的创伤谁提出了刺痛感和无力的右手。肌电图显示手肘周围尺神经病变，内上髁近端传导减少。超声和磁共振成像，尺神经被发现轻度肿胀，并覆盖了额外的滑动肱三头肌以上的髁后区。在肘关节完全屈曲时，这种解剖结构对神经周围的血管产生动态压迫。尽管保守治疗超过2个月，患者的症状改善甚微。采用尺神经减压前移术，效果良好。肱三头肌的额外滑动可压迫神经血管结构并导致手肘尺神经病变。超声检查在评价这种神经血管压迫方面是有用的。
Additional slips of the triceps brachii have been reported in cadaver studies. We report the case of a 48-year-old man with no history of trauma who presented with a tingling sensation and weakness in his right hand. Electromyography revealed ulnar neuropathy around the elbow, with decreased conduction proximal to the medial epicondyle. On ultrasonography and magnetic resonance imaging, the ulnar nerve was found to be mildly swollen and covered by an additional slip of the triceps brachii muscle above the retrocondylar area. Upon full elbow flexion, this anatomy produced dynamic compression of the vessels surrounding the nerve. Despite conservative treatments for over 2 months, the patient had minimal symptom improvement. Decompression and anterior transposition of the ulnar nerve were performed with favorable results. Additional slips of the triceps brachii muscle can compress neurovascular structures and cause ulnar neuropathy at the elbow. Ultrasonography is useful in the evaluation of such neurovascular compression.
