Abstract:Objective To explore the clinical effects of two kinds of open reduction and internal fixation in the treatment of calcaneal fractures. Methods From March 2016 to January 2020, 35 cases of calcaneal fractures were surgically treated in the undergraduate room. According to the random description method, they were divided into 19 cases in the conventional group and 16 cases in the minimally invasive group. The control group received lateral L-shaped incision combined with anatomical calcaneal plate fixation, and the minimally invasive group chose sinus tarsal incision combined with microplate and hollow screw fixation. The VAS scores, Maryland function scores, and calcaneal imaging parameters of the two groups were compared before and after treatment. Clinical efficacy. Results The bone imaging parameters, foot function scores, fracture healing and other curative effects of the two groups of patients after surgery and the last follow-up were significantly improved (P>0.05), and the minimally invasive group had shorter incisions and better incision healing , The difference is statistically significant (P<0.05). Conclusion Both surgical methods have achieved good fracture reduction and internal fixation effects. Among them, the minimally invasive internal fixation of the sinus tarsal incision has a smaller incision and fewer complications, which is beneficial to improve the overall efficacy of the patient.
