目的:探討Zero-p內固定系統在頸椎前路手術的臨床療效。方法:2010年12月~2012年6月,本科採用Zero-p頸椎前路椎間融合器行ACDF術治療頸椎病患者6例,男性5例,女性1例,年齡42歲~72歲,平均年齡56歲,本組中有1例行雙節段Zero-p內固定術。結果:單節段手術時間為(80±20)min,1例雙節段手術時間為130min,術中出血量100~150ml(平均120ml),6例均無吞咽困難。隨訪時間為12~18個月,平均15個月,術後5例獲得滿意的臨床癥狀和神經功能改善,1例不滿意,6例均無吞咽困難。結論:Zero-p內固定系統操作簡單,手術時間短,術中出血量少,術後吞咽困難發生率較低,早期臨床療效滿意。
Objective: To study the clinical outcome of Zero-p internal fixation and fusion System for anterior cervical spine surgery. Methods: 6 patients in which 5 men and 1 woman age ranging from 42 to 72 years with mean age of 56 years underwent Zero-p implantation ACDF procedure from December 2010 to June 2012. 1 patient underwent bisegmental Zero-p fixation surgery and others with monosegmental operation. Results: The operation time were (80±20) minutes in patients operated with monosegmental, 130 minutes with bisegmental. The intraoperative blood loss was 100-150ml (a mean of 120ml). All the cases were follow-up for 12 to 18 months with an average of 13 months. 5 cases had a satisfied neurologic outcome improvement, 1 case complained ambulation dysfunction. All cases didn't suffer from dysphagia after operation. Conclusion: Zero-p internal fixation and fusion system is easy to operate with low complication rates, and has an excellent early clinical outcome.
