To explore the clinical features, treatment and prognosis of the C5 palsy after surgery of cervical spondylosis.
Two hundred and twenty-three cases treated from March 1994 to October 2003 were retrospectively reviewed.
Seven of the 223 cases developed the complication of C5 palsy, manifesting the paresis of the deltoid muscle as well as the sensory deficits and (or) intractable pain in shoulder. The incidence was 3.1%. In this study, 2 cases occurred in the anterior subcorpectomy, 5 cases developed in the laminoplasty with 1 case on the opened side, 3 cases on the hinged side and 1 case on both sides. All the 7 cases with the C5 palsy recovered within 2 weeks to 6 months.
The C5 palsy can develop either anterior decompression or posterior open-door laminoplasty of cervical spondylosis. Generally speaking, patients with postoperative C5 palsy can be cured by conservative measures. And prognosis is good.
探讨颈椎病手术后C5麻痹的临床特征、治疗方法及预后。
回顾性分析1994年3月至2003年10月间治疗的223例患者。
223例患者中有7例发生C5麻痹并发症，表现为三角肌麻痹以及肩部感觉障碍和（或）顽固性疼痛。发生率为3.1%。本研究中，2例发生于椎体次全切除前路减压术，5例发生于单开门椎管扩大成形术，其中1例发生于开门侧，3例发生于铰链侧，1例两侧均发生。7例C5麻痹患者均在2周~6个月内恢复。
颈椎病前路减压术或后路单开门椎管扩大成形术均可发生C5麻痹。一般来说，术后C5麻痹患者经保守治疗可治愈，预后良好。
