摘要
目的研究应用3D打印个体化导板进行S2AI螺钉固定的临床精准性及安全性。方法将2016年8月~2017年8月于我院接受S2AI螺钉固定治疗的40例退行性脊柱侧弯患者分为未采用3D打印个体化导板的对照组及应用3D打印个体化导板的观察组各20例,观察患者椎弓根壁损伤发生情况、S2AI螺钉钉道参数。结果观察组椎弓根壁损伤发生率10.00%,对照组椎弓根壁损伤发生率20.00%,差异有统计学意义(P<0.05);两组S2AI螺钉钉道参数相比较,观察组尾向偏角、外向偏角、钉道最大长度、钉道在骶骨内长度、髂骨宽度、进钉点与皮肤垂直距离均优于对照组,差异有统计学意义(P<0.05)。结论应用3D打印个体化导板进行S2AI螺钉固定可降低患者椎弓根壁损伤发生率,提高临床精准性及安全性,值得推广使用。
Objective To study the clinical precision and safety of S2AI screw fixation using 3D printed individualized guides.Methods 40 patients with degenerative scoliosis treated with S2AI screw fixation in our hospital from August 2016 to August 2017 were divided into control group without 3D printed individualized guide plate and observation group with 3D printed individualized guide plate.20 patients in each group,the occurrence of the pedicle wall injury and the S2AI screw parameters were observed.Results The incidence rate of pedicle wall damage in the observation group was 10.00%,and the incidence of pedicle wall injury in the control group was 20.00%,the difference was statistically significant(P<0.05);Comparing the two groups of S2AI screws,the tail angle,outward declination,the maximum length of the nail path,the length of the pin canal in the sacrum,the width of the ilium,the vertical distance between the entry point and the skin were all better than those in the control group,the difference was statistically significant(P<0.05),Conclusion Using 3D to print individual guide plate for S2AI screw fixation can reduce the incidence of pedicle wall injury,improve clinical accuracy and safety,and is worthy of popularization.
