The authors have observed a series of patients with cervical monoradiculopathies due to extradural compressive disease in whom clinical signs included relief of radicular pain with abduction of the shoulder. Of 22 patients requiring myelography for unremitting radicular pain, 15 experienced relief of pain with shoulder abduction. Thirteen patients showing this sign required surgery and all achieved a good result. Two patients were relieved with additional conservative measures. Pain relief obtained with this maneuver seems to occur by decreasing tension on the nerve root. This shoulder abduction relief sign has not been commonly elicited in the past, and the authors wish to bring attention to its value as an indicator of significant cervical extradural radicular compressive disease.
作者观察了一系列因硬膜外压迫性疾病导致颈单神经根病的患者，其临床体征包括肩部外展时神经根性疼痛缓解。在22例因持续性神经根性疼痛而需要进行脊髓造影的患者中，15例在肩部外展时疼痛缓解。出现此体征的13例患者需要手术治疗，且均取得了良好效果。另外2例患者通过额外的保守治疗得到缓解。通过该动作获得的疼痛缓解似乎是通过减轻神经根的张力实现的。过去这种肩部外展缓解体征并不常见，作者希望引起人们对其作为严重颈硬膜外神经根压迫性疾病指标价值的关注。
