摘　　要：【目的】3D矫形鞋垫在双下肢不等长(LLD)伴下背痛患者中的应用效果。【方法】研制3D打印矫形鞋垫,对符合研究标准的LLD患者定制鞋垫,要求患者行走时穿用,在穿用鞋垫前进行一般情况问询和功能初评,包括疼痛评定、三维步态分析、健康问卷,穿用12周后进行功能末评。【结果】共有5例患者完成研究,患者治疗前有不同程度的行走后下肢关节疼痛和下腰背痛,日常活动受影响,穿用定制鞋垫12周后,关节疼痛及下背痛均减轻。5例患者步频、步幅、步速均有提高,3例双下肢支撑相、摆动相明显趋向正常;5例患者健康状况均明显好转,3个月的穿用过程中,均无足底疼痛、异常感觉等不适主诉,鞋垫也未破裂。【结论】3D打印矫形鞋垫的制作过程步骤清晰,有可操作性。LLD患者穿用定制鞋垫后,对减轻肌肉、关节疼痛,改善步态有较好的治疗效果。随着3D打印软件、材料的发展,打印设备价格的下降,以及3D打印先进的增材制作工艺,3D打印矫形鞋垫的临床应用将会得到推广。【Objective】To observe the effect of 3D orthotic insole in patients with unequal length of lower limbs and lower back pain.【Methods】Research and Development of 3D printing orthotic insoles,We customized 3D printed orthotic insoles for each patient with LLD,who meet the research criteria.We requested the participants to wear it at any time when they are walking.General inquiries and functional preliminary evaluations were made prior to wearing the insole,including pain assessments,3D gait analysis,health questionnaire,and functional final reviews after 12 weeks of wearing the 3D printed orthotic insoles.【Results】A total of 5 patients completed the study.Before treatment,patients complained about various degrees of pain at lower limb joint and lower back through their walks,as well as constrains of daily activities.After 12 weeks of wearing the customized 3D printed orthotic insoles,joint pain and lower back pain were in remission.All five participants have had improvement in their pace frequency,pace stride and the pace speed.Three of them,their support phases and swing phases of lower limbs became normal.The health statuses of all five participants have significantly improved.There were no any complaints,such as uncomfortable heel pain and abnormal feelings during the 12 week clinical study.All 3D printed orthotic insoles remain in good condition after 12 week clinical study.【Conclusion】The 3D printed orthotic insoles are made with clear procedures and practical execution.LLD patients have achieved a much better therapeutic effect on relieving muscle and joint pain as well as improving gait by wearing 3D printed orthotic insoles.With the development of 3D printing software and materials,the dropping price of printing equipment,and the advancing manufacturing process of 3D printing technology,the clinical applications of 3D printed orthotic insoles will be further promoted.
