【摘要】 目的:探讨颈椎后纵韧带骨化症(OPLL)术后C5神经根麻痹的临床特点、治疗及预后。方法:2000年3月至2005年1月,采用后路减压手术治疗OPLL患者157例,其中9例术后出现C5神经根麻痹。回顾性分析9例患者的临床资料,所有患者术后均进行功能康复训练,其中5例患者给予高压氧辅助治疗,随访观察预后情况。结果:本组C5神经根麻痹的发生率为5.7%,包括单开门椎管成形术2例、全椎板切除减压术7例。其临床表现为三角肌、肱二头肌肌力下降至1～2级,肩部及上臂外侧感觉障碍,肱二头肌腱反射减弱或消失。随访1～4年,9例患者的肌力均恢复至3～4级,7例感觉恢复正常。结论:C5神经根麻痹是颈椎后路手术治疗OPLL的并发症之一,经过功能康复训练等保守治疗后肌力、感觉均可获得一定恢复。更多还原

【Abstract】 Objective:To discuss the clinical features,treatment and prognosis of C5 nerve root palsy after posterior surgery of cervical ossification of poseterior longitudinal ligament(OPLL).Method:From March 2000 to January 2005,157 patients with OPLL were treated by posterior decompression,and 9 of them developed C5 palsy after surgery.The patients with palsy underwent functional exercises,and high-pressure oxygen therapy was given to 5 patients.The clinical materials of these 9 patients were reviewed.Result:The incidence of C5 palsy was 5.7% in this study,including 2 after laminoplasty and 7 after laminectomy.The clinical symptom included paresis of deltoid and /or biceps muscles(1-2 grade),sensory deficit in the shoulder area and weakness of tendon reflex of biceps muscle.After a follow-up of 1~4 years,the paralyzed muscles of 9 patients recovered to 3~4 grade,and the sensory of 7 patients recovered to normal.Conclusion:C5 nerve root palsy is one of the complications of cervical OPLL treated by posterior decompression.A good recovery of patients′ power and sensation usually can be reached by functional exercises.更多还原
