目的 探讨观察Mobi-C人工颈椎间盘置换技术治疗颈椎病、颈椎间盘脱出症的临床疗效.方法 自2008-10-2010-03,应用Mobi-C人工颈椎间盘置换术治疗颈椎病8例13个椎间隙、颈椎间盘脱出症5例6个间隙,对手术操作、术中出血、术后影像学检查及临床疗效等进行了分析.结果 患者手术后1周均感到上胸部紧缩感及手指麻木等神经症状明显好转,手指持物及下肢肌力增加.术后1周X线片检查显示:椎间隙高度、位置良好.随访6～23个月,根据JOA评分:从手术前的平均9.5分增加到随访时16.5分,术后改善率93.4%.X线摄片示无椎间隙的高度丢失、椎体后缘自发骨化及后凸畸形,动力性摄片未见不稳、假体移位、松动征象.术后未出现喉头水肿、伤口血肿、切口感染、声音嘶哑等并发症.结论 Mobi-C人工颈椎间盘置换术治疗颈椎病、颈椎间盘突出症能获得优良的近期疗效.%objective To observe the clinic effecl of Mobi-C artifitial cervical disc prosthesis on treating cervical spondylotic myelopathy and cervical disc protrusion. Methods From October 2(X)8 to March 2010,8 cases(13 spacs )of cervical spondylotic myelepathy anrl 5 cases(6spacs)of cervical disc protrusion were treated surgically by cervical arthroplasty using Mobi-C disc prosthesis. The material include the surgery procedures, operative time,blood loss,radiological examinations,clinical effect and complications were analyzed. Results The neurologic symptoms were relieved obviously within one week postoperative in all patients. Low limb muscle strength increased, upper limb abnormal sensation disappeared and limb moved more agile. Cervical X-ray film showed cervical curve anil position of Mobi-C prosthesis resumed normal. The intervertebral space height were maintaining original height in all cases. Followed up average 15 months (6~23 months). The average JOA score increased from 9.5 preoperative to 16.5 at followed up. There was no neurological or vascular complications during the operation or after surgery. There was no prosthesis subsidence or excursion,no ossification and loss of lordosis could be found in the replaced levels. Replaced segment maintain stability and segment motion. Conclusion Cervical arthroplasty using Mobi-C prosthesis can obtain a good and excellent early outcome for spondylotic myelopathy and cervical disc protrusion.
