Small Splint External Fixation Treatment With A Combined With 3D Printing Colles Fracture Clinical Research

ObjectiveTo explore the short-term clinical efficacy of manipulation reduction small splint combined with 3D printing external fixation of wrist brace for Colles fracture and the advantages of the use of brace.MethodsA total of 60 patients with Colles fracture who were treated in zhongshan hospital of traditional Chinese medicine from February to December 2017 were selected.Patients were randomly divided into 2 groups according to the order of treatment,with 30 patients in the control group,including 13 males and 17 females,aged from 16 to 66 years(49.46±12.63)years.In the experimental group,there were 30 cases,12 males and 18 females.Age:14～68 years,mean(46.73±14.40)years,3～19h.All the patients in the experimental group and the control group were treated with the same doctor’s technique to complete the fracture.X-ray showed that the small splints were applied for external fixation after the satisfactory reduction.After 1 week of fracture treatment,the experimental group removed the small splints and replaced the 3D printing brace to maintain fixation until the fracture healed.In the control group,small splints were maintained until the fracture healed.The two groups of patients were treated with wrist X-ray before and after reinstatement and 4 weeks after reduction,respectively,and the volar Angle,ulnar Angle and radial height were observed and compared.VAS score and swelling degree score of the two groups before and after reduction,1 and 2 weeks after reduction were recorded.Cooney and PRWE scores of the two groups were compared after 6-8 weeks of external fixation.ResultsThere was no statistical difference in the VAS score and swelling degree between the two groups before and after reduction,and after 1 and 2 weeks after reduction.Cooney and PRWE scores of the experimental group were better than those of the control group after 6-8 weeks(P<0.05).Conclusion3D printing supports are light and breathable,comfortable and beautiful,and convenient for dressing.The combination of small splint time division applied to Colles fracture has a definite clinical effect,which enriches the means of external fixation treatment.It is believed that with the deepening of clinical research,the design and materials of 3D printing supports have improved,and their application in future medical treatment will be further developed.
