Compression of the lateral antebrachial cutaneous nerve is a rare clinical entrapment syndrome often overlooked as an initial etiology of pain. We present a case of an episodic upper limb painful movement disorder (myoclonus) in a 16-yr-old adolescent girl with a remote history of a surgically stabilized supracondylar humeral fracture who was later found to have entrapment of the lateral antebrachial cutaneous nerve. The incidence of a painful myoclonus triggered by a peripheral nerve entrapment is unknown. Combining a history and physical examination, electromyography, nerve conduction studies, and ultrasound enabled us to make an accurate diagnosis that was confirmed by resolution of symptoms after surgical release. This study conforms to all CARE guidelines and reports the required information accordingly (see Supplemental Check list, Supplemental Digital Content 1, http://links.lww.com/PHM/A855).
前臂外侧皮神经受压是一种罕见的临床嵌压综合征，常被忽视为疼痛的初始病因。我们报告了一例 16 岁少女的间歇性上肢疼痛运动障碍（肌阵挛），该患者有肱骨髁上骨折的手术史，后来发现有前臂外侧皮神经受压。外周神经嵌压引起疼痛性肌阵挛的发生率尚不清楚。结合病史和体格检查、肌电图、神经传导研究和超声检查，我们做出了准确的诊断，并在手术后症状缓解后得到了证实。本研究符合所有 CARE 指南，并相应地报告了所需的信息（见补充检查表，补充数字内容 1，http://links.lww.com/PHM/A855）。
