摘　　要：目的探讨3D打印辅助预弯钛板在老年腕关节骨折中的应用效果。方法选取2022年1月至2023年9月上饶市人民医院收治的60例老年腕关节骨折患者作为研究对象,按照随机数字表法分为观察组和对照组,每组各30例。观察组采用3D打印预弯钛板行切开复位内固定手术,对照组则采用常规切开复位内固定手术治疗。统计并比较两组患者的手术时间、术中出血量、愈合与并发症发生情况;比较两组患者术后掌倾角、尺偏角大小和桡骨高度,以及三者的丢失情况;比较两组的腕关节屈伸范围、尺桡偏、前臂旋转活动度、握力;并采用Cooney腕关节功能评分评价两组患者的腕关节功能。结果所有患者均随访6个月,骨折均达到良好愈合,无相关并发症发生。观察组的手术时间短于对照组,差异有统计学意义(P<0.05);两组患者的术中出血量比较,差异无统计学意义(P>0.05)。两组患者术后即刻的掌倾角、尺偏角比较,差异无统计学意义(P>0.05);观察组术后即刻的桡骨高度高于对照组,差异有统计学意义(P<0.05)。术后即刻,观察组的掌倾角、尺偏角丢失均小于对照组,桡骨高度丢失短于对照组,差异有统计学意义(P<0.05)。术后6个月,观察组的腕关节屈伸范围、尺桡偏、前臂旋转活动度均大于对照组,差异有统计学意义(P<0.05);两组患者的握力比较,差异无统计学意义(P>0.05)。术后3个月,两组患者的Cooney腕关节功能评分比较,差异无统计学意义(P>0.05)。结论3D打印个性化辅助预弯钛板治疗老年性腕关节骨折短期随访效果满意,对骨折复位固定精准,减少手术时间及出血量的同时,关节面复位良好且固定有效,术后腕关节功能恢复良好,值得临床推广。Objective To explore the application effect of 3D printing assisted prebending titanium plate in the treatment of wrist fractures in the elderly.Methods A total of 60 elderly patients with wrist fracture admitted to ShangRao People's Hospital from January 2022 to September 2023 were selected as the research objects.According to the random number table method,they were divided into observation group and control group,with 30 cases in each group.The observation group was treated with open reduction and internal fixation with 3D printing prebending titanium plate,and the control group was treated with conventional open reduction and internal fixation.The operation time,intraoperative blood loss,healing and complications of the two groups were recorded and compared.The palmar inclination angle,ulnar deviation angle,radial height and the loss of the three were compared between the two groups after operation.The wrist flexion and extension range,radioulnar deviation,forearm rotation range of motion,and grip strength were compared between the two groups.Cooney wrist function score was used to evaluate the wrist function of the two groups.Results All patients were followed up for 6 months,and the fractures healed well without related complications.The operation time of the observation group was shorter than that of the control group,the difference was statistically significant(P<0.05).There was no significant difference in intraoperative blood loss between the two groups(P>0.05).There were no significant differences in palmar tilt angle and ulnar deviation angle between the two groups immediately after operation(P>0.05).The radial height of the observation group was higher than that of the control group immediately after operation,and the difference was statistically significant(P<0.05).Immediately after operation,the loss of palmar tilt angle and ulnar deviation angle in the observation group were less than those in the control group,and the loss of radial height was shorter than that in the control group,and the differ
