【摘要】 目的 分析3D打印在老年髋部骨折的应用效果。方法 选取2019年3月—2021年2月该院收治的58例老年髋部骨折患者，按照随机数表法分两组，各29例。参照组给予常规手术治疗，研究组采用3D打印技术进行辅助治疗，比较两组手术复位效果、手术相关指标及术后不同时间点的髋关节功能。结果 研究组手术复位优良率略高于参照组（100.00%vs 96.55%），但差异无统计学意义（P>0.05）。研究组手术时间（75.38±9.83）min、术后首次下床活动时间（1.86±0.40）d均短于参照组，术中出血量（225.80±36.72）m L少于参照组，差异有统计学意义（t=2.707、3.435、6.186,P<0.05）。术后2个月、4个月时，研究组髋关节功能Harris评分分别为（72.37±8.55）分、（81.25±9.83）分均高于参照组，差异有统计学意义（t=2.352、2.958,P<0.05）。结论 将3D打印技术应用于老年髋部骨折手术中，具有快捷、创伤小及术后恢复快等优点，有助于提高手术复位效果，促进患者髋关节功能恢复。更多还原

【Abstract】 Objective To analyze the application effect of 3D printing in elderly hip fractures. Methods A selection of 58 elderly hip fracture patients admitted to the hospital from March 2019 to February 2021 were divided into two groups according to the random number table method, with 29 cases in each group. The reference group was given conventional surgical treatment, and the study group used 3D printing technology for adjuvant treatment. The effect of surgical reduction, operation-related indicators and hip joint function at different time points after surgery were compared between the two groups. Results The excellent and good rate of surgical reduction in the study group was slightly higher than that in the reference group(100.00% vs 96.55%), but the difference was not sta-tistically significant(P>0.05). The operation time of the study group was(75.38±9.83) min and the time to get out of bed for the first time after operation(1.86±0.40) d were shorter than those of the reference group, and the intraoperative blood loss(225.80 ±36.72)mL was less than the reference group, the difference was statistically significant(t=2.707, 3.435, 6.186, P<0.05). At 2 months and 4 months after surgery, the Harris scores of hip joint function in the study group were(72.37±8.55) points and(81.25±9.83) points respectively,higher than those of the reference group, the difference was statistically significant(t=2.352, 2.958, P<0.05). Conclusion The application of 3D printing technology to elderly hip fracture surgery has the advantages of quickness, less trauma and quick postoperative re-covery, which can help improve the effect of surgical reduction and promote the recovery of patients’ hip joint function.更多还原
