【摘要】 目的观察3D打印辅助跗骨窦小切口复位内固定治疗跟骨骨折的效果。方法选取2016年1~12月新塘医院收治的42例跟骨关节内骨折患者作为研究对象,在征得患者以及患者家属的同意下将所有患者分为实验组与对照组,每组各21例。对照组患者给予常规跟骨外侧"L"型延长切口复位钢板内固定治疗,实验组患者给予3D打印辅助跗骨窦微创切口复位内固定治疗,观察比较两组患者术后骨折的愈合情况及临床恢复效果。结果实验组患者治疗后Bohler角、Gissane角优于对照组,实验组患者术后第9个月个体跟骨治疗优良率明显优于对照组,实验组患者的不良反应发生率(9.5%)明显低于对照组(19.0%),差异均有统计学意义(P<0.05)。结论对于跟骨关节内骨折患者给予3D打印辅助跗骨窦小切口复位内固定治疗有利于个体跟骨骨折复位,缩短患者跟骨骨折愈合时间,降低不良反应发生率。更多还原

【Abstract】 Objective To observe the clinical efficacy of 3D printing assisted reduction and internal fixation with tarsal sinus small incision in treatment of calcaneal fractures.Methods 42 patients with intra-articular calcaneal fractures treated in Xintang Hospital from January to December 2016 were selected as the subjects,and divided into experimental group and control group,21 cases in each group.The control group were given conventional calcaneal lateral "L" type extended incision reduction plate internal fixation,the patients in the experimental group were treated with 3D printing assisted minimally invasive reduction and internal fixation of the tarsal sinus.The postoperative fracture healing and clinical recovery effect were observed and compared between the two groups.Results The Bohler angle and Gissane angle in the experimental group were better than those in the control group after the treatment.The excellent and good rate of calcaneal treatment in the experimental group was significantly better than that in the control group 9 months after operation.The incidence of adverse reactions in the experimental group(9.5%) was significantly lower than that in the control group(19.0%),the differences were statistically significant(P<0.05).Conclusion The treatment of intra-articular calcaneal fractures with 3D printing assisted reduction and internal fixation with small incision of the tarsal sinus is beneficial to the reduction of calcaneal fractures,shortening the healing time of calcaneal fractures and reducing the incidence of adverse reactions.更多还原
