Abstract: Objective To explore the therapeutic effect of the post-outer incision incision reset with Chinese medicine in the treatment effect of the spin IV-ankle fracture. Methods 80 cases of post-spin IV ankle fracture patients admitted to our hospital from January 2016 to June 2018 were selected into the study, and 40 cases were randomly divided into observation group and control group. Both groups were given post-outer incision reset fixed treatment fractures, after surgery the patients of the control group were given routine treatment, the patients of the observation group given Chinese medicine soup in-service treatment, the recoveries of two sets of surgical indicators were observed after follow-up 52 weeks, AOFAS ankle and posterior foot scoring function were observed after treatment for 26 weeks. Results The pain relief time, deflating time, fracture healing time and joint function recovery time were(5.71±0.96)d,(6.14±1.03)d,(50.83±8.17)d,(65.24±6.28)d. The control group was(6.62±1.77)d,(7.24±1.69),(71.02±10.26)d,(77.13±11.48)d. Compared with the surgical recovery index of two groups, the observation group was significantly better than that of the control group, and the difference was statistically significant(P<0.05). After 26 weeksof follow-up study, observation group indicated that AOFAS scores in 22 cases were excellent, 15 cases good, 3 cases not bad, the excellent and good treating effect rate was up to 92.50%. The treating effects of patients of the control group showed that AOFAS scores in 16 cases were excellent, 14 cases good, 10 cases not bad, the excellent and good treating effects were 75.00%. The two groups had a high rate of AOFAS score, but the observation group was significantly higher than the control group, and the difference was statistically significant(P<0.05). In the observation group, 4 patients had complications, the incidence rate was 10.0%, 4 patients had drug resistance, and the treatment compliance was 90.00%. There were 11 cases of complications in the control group, with an incidence rate of 27.50%. During the treatment, 12 cases took medicine against the doctor's advice, and the treatment compliance was 70.00%. Conclusion For treating supination extorsion Ⅳ°ankle fractures, open reduction and internal fixation with Chinese medicine treatment has obvious advantages,the complications are low. Compared with regular treatment, it is not only welcomed in patients,which can significantly shorten the recovery time after the surgery, but also can significantly improve the ankle functions.
