个体化3D打印手术引导模板辅助治疗发育性髋关节脱位的效果分析

Effect of individualized 3D printed surgical guidance template in treatment of developmental dislocation of hip joint

目的探讨个体化3D打印手术引导模板辅助治疗发育性髋关节脱位的效果。方法选取该院2012年5月至2017年5月收治的88例发育性髋关节脱位患儿为研究对象,分为对照组与观察组,每组44例。对照组给予常规治疗,观察组通过3D打印技术制作成仿真模型及手术模板,制订个体化的治疗方案。对比两组患儿形态学参数、围术期指标、影像学评定结果、肢体功能及日常生活能力。结果两组患儿形态学参数中股骨颈干角、股骨前倾角、髋臼短轴、髋臼长轴、髋臼表面积相比均无明显差异(P>0.05)。与对照组相比,观察组患儿手术时间短、出血量少、辐射次数少,差异有统计学意义(P<0.05),但住院费用无明显差异(P>0.05)。与对照组相比,观察组患儿Mackay与Severin评价的优良率无明显差异(P>0.05)。与治疗前相比,治疗后两组患儿FMA及Barthel均升高,观察组变化更明显,差异有统计学意义(P<0.05)。结论利用个体化3D打印手术引导模板辅助治疗发育性髋关节脱位患儿的矫正效果明显,围术期指标较好,能够有效地改善肢体功能及日常生活能力。

Objective To explore the effect of individualized 3D printing surgical guidance template in the treatment of developmental dislocation of hip joint.Methods A total of 88 children with developmental dislocation of hip joint treated in this hospital from May 2012 to May 2017 werev selected as the research objects and divided into the control group and the observation group,with 44 cases in each group.The observation group used 3D printing technology to make a simulation model and surgery template,and developed individualized treatment plans.The morphological parameters,perioperative indicators,imaging evaluation results,limb function and daily living ability were compared in the two groups.Results There was no significant difference between the morphological parameters femoral neck stem angle,femoral rake angle,acetabular short axis,acetabular long axis,acetabular surface area between the two groups(P>0.05).Compared with the control group,the observation group had shorter operation time,less bleeding and less radiation,and the difference was statistically significant(P<0.05),but no significant difference in hospital costs(P>0.05).Compared with the control group,there was no significant difference in the optimal rate by Mackay and Severin evaluation(P>0.05).Both FMA and Barthel scores of the two groups increased after treatment compared with before treatment,and the increase was more significant in the observation group with statistically significant difference(P<0.05).Conclusion Individualized 3D printed surgical guidance template can be used to assist the treatment of developmental dislocation of hip joint,which has significant correction effect and good perioperative indicators.Meanwhile,it can effectively promote the improvement of limb function and daily living ability.
