摘要
目的 评价颈椎后路单开门椎管扩大成形术中Centerpiece钛板的临床应用及疗效。方法 自2010-03-2011-12采用Centerpiece钛板内固定术治疗34例颈椎疾患。结果 手术时间为(140±15)min,术中出血量为(275±25)ml。所有患者获得随访8-18个月,平均8.5个月,1例出现C5神经根麻痹,1例出现螺钉松动,5例出现轴性症状。术前JOA评分为(9.8±2.9)分,末次随访时为(15.3±1.1)分,改善率达(65.4±9.3)%。影像学复查示C5节段椎管矢状径术前(10.4±1.5)mm,末次随访时为(15.6±1.4)mm,椎管扩大率为(68.3±8.9)%。C5节段脊髓后移(3.13±1.82)mm,与术前比较差异有统计学意义(P〈0.05)。颈椎Cobb角术前为(13.1±1.6)°,末次随访时为(11.3±1.8)°,术前与末次随访时比较,差异无统计学意义(P〉0.05)。结论 Centerpiece钛板应用于颈椎单开门椎管扩大成形术安全有效,术后神经功能恢复良好,早期疗效满意。
Objective To explore the clinical application and efficacy of Centerpiece titanium plate fixation in open door laminoplasty. Methods A total of 34 patients received the unilateral open-door cervical expansive laminoplasty fixed by centerpiece plate from March 2010 to December 2011. Results The average operation time was (140±15)min, the average intraoperative blood loss was (275±25)ml. All patients were followed up for 8-18 months(mean 8.5 months). C5 palsy was noted in 1 case at 3 day after operation, 1 case oceurcd screw loosening, 5 patients got axial symptoms. The average preoperative JOA score was (9.8±2.9) and (15.3±1.1) at final follow-up after operation, with the improvement rate of (65.4±9.3)%. The mean sagittal diameter of C5 spinal canal was (10.4±1.5)mm before operation and (15.6±1.4)mm at final follow-up,with the expansion rate of (68.3±8.9)%. Cervical curvature index was (13.1±1.6)% preoperatively, it was (11.3±1.8)% at final follow-up interval, indicating that cervical curvature index made no progress at final follow-up interval (P 〉0.05). Conclusion Unilateral open-door expansive laminoplasty plus centerpiece titanium plate fixation is reliable, nerve recovery and the early clinical efficacy is satisfactory.
