C5 nerve root palsy is a well-known complication after anterior or posterior cervical decompression. Many theories have been proposed but the etiology is still unclear. The use of a winged expandable cage after single or multiple corpectomy is among the used techniques in reconstructing the cervical spine. Herein we report a case of C5 palsy after a three-level corpectomy and reconstruction using this device for the treatment of cervical spondylosis. In our case the preexisting foraminal stenosis, wide anterior decompression and partial improvement of cervical alignment were factors supposed contributing to the palsy.
C5神经根麻痹是颈椎前路或后路减压术后一种众所周知的并发症。虽然已经提出了许多理论，但病因仍不清楚。在单节段或多节段椎体次全切除术后使用带翼可扩张椎间融合器是重建颈椎的常用技术之一。在此，我们报告一例在三级椎体次全切除并使用该装置重建治疗颈椎病后发生C5麻痹的病例。在我们的病例中，术前存在的椎间孔狭窄、广泛的前路减压以及颈椎对线的部分改善被认为是导致麻痹的因素。
