| Objective For digital design plywood and elasticity with biomechanical analysis and clinical research,to discuss the treatment of Colles fracture effectiveness.Methods The related finite element software modeling,biomechanical tes t,.data collection and analysis.Use prospective randomized controlled cl inical research cohort study,collect the subjects 60 cases,divided into the experimented group and the control group(n = 30).Observation indexe s with limb swelling a grade,pressure sores,VAS pain score,the number of splint adjustment score and score Gartland-Werley wrist function.Befo re treatment,the observation time point after treatment 1,3,5,7,30 a nd 90 days.Complete the follow-up work and data records.Results Digital design splint fixed model than traditional splint fixed model of fracture end,plywood,and the displacement and stress of soft ti ssue.Swelling rating:1 and 30 days before and after treatment,there was no statistically significant difference(P>0.05);1 day after treatment,e xperimented group score was 2.26±0.44,control group score was 2.50±0.40,the difference was statistically significant(P<0.05);3 days after treat ment,experimented group score was 2.04±0.49,control group score was 2.33±0.40,the difference was statistically significant(P<0.05).5 days after treatment experimented group score was 1.73 ± 0.31,the control group sco re was 2.00 ± 0.36,the difference was statistically significant(P<0.05).7 days after the treatment experimented group score was 1.05±0.20,the co ntrol group score was 1.50 ± 0.14,the difference was statistically signif i cant(P<0.05).Pressure sores rating:1 and 30 days before and after treatm ent,two groups of pressure sores score of 0;5 days after treatment,a gro up score was 1.20±0.20,the control group score was 2.02±0.50,the diffe rence was statistically significant;7 days after treatment,experimented group score was 1.20±0.2,the control group score was 1.75±0.3,the dif ference was statistically significant.VAS pain score:30 days before and after treatment,there was no statistically significant difference(P>0.05);1 day after the treatment of a group score was 5.70±1.70,the contro 1 group score was 6.50±1.10,the difference was statistically significan t(P<0.05);3 days ater treatment experimented group score was 4.30 ± 1.20,control group score was 5.70 ±1.40,the difference was statistically s ignificant(P<0.05);5 days after treatment a group score was 2.50±1.30,the control group score was 3.90 ± 1.10,the difference was statistically significant(P<0.05);7 days after the treatment of a group score was 1.30±0.30,the control group score was 2.30±0.21,the difference was statis tically significant(P<0.05).Splint to adjust the number:a group to adju st to 3 people,not adjust 16 people.Control adjustment of 11 people,did not adjust the seven people,the difference was statistically significan t(P<0.05).Wrist joint function score:30 days after treatment,a group sc ore was 8.10±2.30,the control group score was 9.56±1.99,the difference was statistically significant(P<0.05).90 days after treatment,a group s core was 2.79 ± 1.50,the control group score was 2.82±1.10,there was no s tatistically significant difference(P>0.05).Conclusion Digital design plywood safety and efficacy is better than tra ditional splint fixed model,reducing the fracture displacement,plywood again loose,risk of pressure ulcers,fascia compartment syndrome,etc.Di gital design plywood at the beginning of the fracture to improve limb.swe lling,pressure ulcers,For improving patient forward wrist function aspe ct,has the good performance,no obvious difference. |
