Abstract Objective: To evaluate the clinical efficacy of solid image contrast technique combined with cutting prefabrication technique in the treatment of special ankle fracture. Methods: A retrospective study was conducted on 63 cases of special type ankle fractures admitted to the Affiliated Hospital of Chengde Medical University from May 2015 to June 2022. According to the preoperative planning method, the patients were divided into the digital technology group (using solid image comparison technology combined with cutting prefabrication technique for preoperative planning, 31 cases) and the radiological technology group (using radiological data for preoperative planning, 32 cases). Ankle bone reconstruction surgery was performed at a scheduled time, and data of various indicators before, during, and after surgery were collected for comparative analysis. Results: The preoperative planning cost, preoperative planning time, and Burwell-Charnley anatomical reduction rate in the digital technology group were higher than those in the radiological technology group, and the differences between the two groups were statistically significant (P<0.05). The total intraoperative blood loss and intraoperative time in the digital technology group were lower than those in the radiological technology group, and the differences between the two groups were statistically significant (P<0.05). All patients were followed up for 9 to 13 months with an average of (11.23±2.62) months. The fracture healing time, full weight-bearing time, and complication rate in the digital technology group were lower than those in the radiological technology group, and the differences between the two groups were statistically significant (P<0.05). The AOFAS score in the digital technology group was higher than that in the radiological technology group, and the differences between the two groups were statistically significant (P<0.05). The main effects of time, group, and the interaction between time and group on the plantar pressure and ROM degrees on the affected side in both groups were statistically significant (P<0.001). Conclusion: The application of solid image comparison technology combined with cutting prefabrication technique in the treatment of special type ankle fractures has a definite clinical efficacy, with a low incidence of complications. However, it may increase patient medical expenses and preoperative planning time.
