Abstract: Objective  To explore the efficacy and safety comparison of intelligent small splints and polymer plaster fixation for the treatment of distal radius fractures in the elderly.Methods  Forty elderly patients with distal radius fractures who were diagnosed and treated in our hospital from January 2021 to December 2022 were selected as the research subjects.They were divided into two groups using a random number table method,with 20 cases in each group.The control group was treated with polymer gypsum fixation,while the treatment group was treated with intelligent small splints combined with polymer gypsum fixation.Observe the reduction status (palm tilt angle,ulnar deviation angle,radius height),joint function (DASH score),pain (VAS score),joint range of motion (wrist flexion,radius deviation,ulnar deviation,back extension,pronation,and supination),and complications of the two groups of patients after treatment.Result  Before treatment,there was no statistically significant difference (P＞0.05) in the values of palmar inclination,ulnar deviation angle,and radius height between the two groups.After treatment,the values of palmar inclination,ulnar deviation angle,and radius height increased compared to before treatment,and after treatment,the values of palmar inclination,ulnar deviation angle,and radius height in the treatment group were higher than those in the control group,with a statistically significant difference (P<0.05).Before treatment,there was no statistically significant difference in DASH and VAS scores between the two groups (P＞0.05).After treatment,both DASH and VAS scores decreased compared to before treatment,and the DASH and VAS scores in the treatment group were lower than those in the control group (P<0.05).After treatment,the joint mobility of palm flexion,radial deviation,ulnar deviation,back extension,pronation,and supination in the treatment group was significantly higher than that in the control group (P<0.05).After treatment,the total incidence of complications in the control group was 20.00% (4/20),slightly higher than that in the treatment group of 5.00% (1/20),but the difference was not statistically significant (P＞0.05).The patients were followed up for 6 months.At the end of follow-up,there was no significant difference in treatment satisfaction between the two groups （P＞0.05).Conclusion  The combination of intelligent small splints and polymer gypsum fixation therapy is superior to polymer gypsum fixation therapy alone in terms of reduction,joint function,pain,and joint mobility.
