摘　　要：C5神经根麻痹是一种以术后新发三角肌无力为特征的疾病,是颈椎手术最常见的术后并发症之一,尽管其有自限性及较好的预后,但却是患者术后生活质量下降的一个重要原因。C5神经根麻痹的危险因素包括人口学因素、临床因素、影像学因素等,发病机制尚不明确,既往的主流学说为脊髓损伤学说及神经根拴系学说,近年来提出了术前脊髓旋转不良及摆体位期间胶带引起的肩部牵拉等机制。本文结合近年来解剖学及影像学方面的研究,对C5神经根麻痹的发生率、危险因素及发病机制进行综述。C5 palsy is a postoperative condition characterized by aggravated muscle weakness mainly in the C5 region,representing one of the most common postoperative complications after cervical spine surgery.Despite its self-limiting nature and generally favorable prognosis,it remains a significant contributor to decreased postoperative quality of life for patients.Risk factors associated with C5 palsy include demographic,clinical,and radiological factors,while the precise pathogenesis remains unclear.Historically,the prevailing theories have centered around spinal cord injury and nerve root tethering;however,recent propositions include mechanisms such as preoperative spinal malrotation and shoulder traction induced by tape during positioning.This article presents an overview of the incidence,risk factors,and pathogenesis of C5 palsy within the context of recent anatomical and imaging studies.
