Abstract:
Objective:To investigate the clinical efficacy of 3D printed individual model combined with hyperbaric oxygen（HBO）therapy in treating complex ankle fracture，and to evaluate the therapy’s effect on prognosis.Methods:The clinical data of 45 patients with complex ankle fractures treated in the Department of Orthopedics of Penglai People’s Hospital from January 2017 to January 2021 were analyzed retrospectively. According to different treatment methods，they were divided into 3D model group（ n=21）and combined group（ n=24）. In addition，other 37 complex ankle fracture patients，who were treated in the Department of Orthopedics of Penglai People’s Hospital from January 2014 to December 2016 and had complete clinical data and detailed follow-up records，were selected as control group（conventional group）. The conventional group was given traditional surgery for complex ankle fractures，i.e.，after fracture reduction，the medial malleolus was fixed with steel wire tension band or screws，and the lateral malleolus was fixed with screws and steel plates. In the 3D model group，the strategy and approach of surgical operation were simulated and designed based on 3D printed individual models before operation. The combined group was additionally treated with HBO on the basis of the treatment of the 3D model group. The operation time，hospital length-of-stay，time to first ambulation，clinical fracture healing time，and the intraoperative bleeding loss of the three groups were observed and recorded，so as to compare the therapeutic effects of the three groups. All patients were followed up for one year. The functional recovery of postoperative ankle fracture was evaluated by Olerud-Molander Ankle Score（OMAS）. The incidences of postoperative complications were recorded. Results:The total effective rate of the 3D model group（95.24%）and the combined group（100.00%）were significantly higher than that of the conventional group（72.97%）（ P<0.05）. Regarding the operation time，hospital length-of-stay，time to first ambulation，clinical fracture healing time，and intraoperative bleeding loss，the results of the 3D model group and the combined group were significantly shorter or lower than those of the conventional group（ P<0.05）；the time to first ambulation and clinical fracture healing time of the combined group were significantly shorter than those of the control group（ P<0.05）；there was no statistically significant difference in the operation time，hospital length-of-stay，and intraoperative bleeding loss between the 3D model group and the combined group（ P>0.05）. All patients were followed up with a follow-up rate of 100.0%. The OMAS outcomes of the 3D model group and the combined group at the 1st，3rd，6th，and 12th month after operation were significantly higher than those of the conventional group at the same time points（ P<0.05），and the OMAS outcomes of the combined group at the 1st，3rd，6th，and 12th month after operation were significantly higher than those of 3D model group at the same time points（ P<0.05）. The incidence of postoperative complications was 16.22% in the conventional group，the incidence of deep venous thrombosis（DVT）was 4.8% in the 3D model group，and no complication was found in the combined group. Conclusion:The 3D printed individual model combined with HBO therapy has sound clinical efficacy and prognosis in treating complex ankle fracture. It can shorten the clinical fracture healing time and facilitate the rapid recovery of ankle function，therefore，it should be widely promoted in clinical practices.
