弧轨自锁椎弓根矫形固定器Ⅱ(ALPFⅡ)治疗脊柱疾病临床应用研究

目的：探讨弧轨自锁椎弓根矫形固定器Ⅱ（ALPFⅡ）治疗脊柱疾病的临床疗效。方法：86例脊柱疾病患者,其中男49例,女37例;年龄18～69岁,平均36.8岁。应用ALPFⅡ治疗,并随访。结果：86例获随访,时间9～30个月,平均12个月。患者神经功能、脊柱活动、腰背痛和下肢痛的改善率分别为94.1%、65.9%、92.1%和87.4%,术前后椎体前、后缘高度恢复均明显（P〈0.01,P〈0.05）,后凸角得到满意矫正（P〈0.01）。未发现钉棒松动、断裂。结论：ALPFⅡ治疗脊柱疾病是一种操作安全简便、容易掌握、复位良好、疗效可靠、并发症少的治疗方法。

Clinical curative effect of the treatment of the disease of vertebral column by the arc-track private lock pedicle orthopaedics fixation system (ALPFⅡ)

Objective：To approach the clinical curative effect of treatment of the disease of vertebral column by the arc-track private lock pedicle orthopedics fixation system（ALPFⅡ）. Methods： Eighty-six cases were treated by useing ALPFⅡ. The average age of the cases was 36.8 years（range from 18 to 69 years）,the male was 39 cases and the female was 37 cases.The results were evaluated and all the cases were followed-up. Results：All the patients were followed-up for 9 to 30 months. The amelioration of patients nerve function,spinal motion,low back pain and leg pain was 94.1%,65.9%,92.1% and 87.4% respectively. The height of anterior and posterior border after operation were improved greatly than that before operation（P〈0.01,P〈0.05）. The X-ray films showed that the angle of kyphosis was also improved significantly（P〈0.01）. Conclusion：To tr-eat spinal column disease,ALPF II is a kind of operation safety simple, easy control, reset good, curative effect credibility, the complications little of treatment method.
