颈椎单开门椎板成形术后C5神经根麻痹的研究进展

Progress of C5 Nerve Root Palsy after Open-Door Cervical Expansive Laminoplasty

术后颈5神经根麻痹(C5 nerve root palsy, C5P)是颈椎单开门椎板成形术(open-door cervical expan-sive laminoplasty, LAMP)后常见且可能导致永久神经功能缺陷的并发症,这极大程度影响了对该手术疗效的判断及患者的手术满意度。C5P的确切病因病机尚未完全明确,多数学者支持神经根栓系或脊髓再灌注损伤相关学说。本文结合现有国内外文献对LAMP术后C5P的临床特征、发生率、危险因素、预防措施、治疗及预后做一综述。

Postoperative cervical nerve root palsy (C5P) is a common complication after open-door cervical expansive laminoplasty (LAMP) and may lead to permanent neurological deficits, which greatly af-fects the judgment of the efficacy of the procedure and the patients’ satisfaction with the surgery. The exact etiology of C5P has not been fully clarified, and most scholars support the theory of nerve root embolization or spinal cord reperfusion injury. In this paper, we review the clinical character-istics, incidence, risk factors, preventive measures, treatment and prognosis of C5P after LAMP with reference to the existing literature at home and abroad.
