【摘要】 目的 综述颈椎术后C₅麻痹（C₅ palsy,C₅P）研究进展，为临床治疗C₅P患者提供参考。方法 广泛查阅国内外颈椎术后C₅P相关文献，系统性阐述C₅P发病机制、危险因素、临床表现及诊断、预防、治疗措施新进展。结果 C₅P为颈椎术后出现的C₅神经支配区肌肉无力，表现为肩外展、屈肘受限，发生率>5%，可能由节段性脊髓损伤或神经根机械损伤导致。对于存在危险因素患者，术中仔细操作及采取预防性措施可减少术后C₅P的发生。大部分患者经药物治疗、物理治疗等保守治疗后功能可恢复，6个月以上无明显好转者可予以手术干预，可选用椎间孔减压、神经移位等手术方案。结论 有关C₅P发病机制及预防措施等已取得一定研究进展，但对于干预时机和手术方式仍需进一步研究。更多还原

【Abstract】 Objective To review the research progress of C₅ palsy（C₅P） after cervical surgery,providing new clinical intervention ideas for the C₅P patients.Methods The relevant literature domestically and abroad was extensively consulted and the latest developments in the incidence,risk factors,manifestations and diagnosis,prevention,and intervention measures of C₅P were systematically expounded.Results C₅P is characterized by weakness in the C₅ nerve innervation area after cervical decompression surgery,manifested as limited shoulder abduction and elbow flexion,with an incidence rate more than 5%,often caused by segmental spinal cord injury or mechanical injury to the nerve roots.For patients with risk factors,careful operation and preventive measures can reduce the incidence of C₅P.Most of the patients can recover with conservative treatment such as drug therapy and physical therapy,while those without significant improvement after 6 months of treatment may require surgical intervention such as foraminal decompression and nerve displacement.Conclusion Currently,there has been some advancement in the etiology and intervention of C₅P.Nevertheless,further research is imperative to assess the timing of intervention and surgical protocol.更多还原
