This is Sungyeon Lee, and my topic is arthroscopic-assisted minimal invasive surgery for malleolar fractures, a comparative study with open reduction and internal fixation. There is nothing to disclosure. With the recent trend of increasing arthroscopic-assisted surgical procedure, you can apply arthroscopic-assisted reduction and internal fixation in the following cases. In ankle fractures, 20-79% of cases with articular lesion have been reported, and Tachow et al. say that physical examination and a simple x-ray alone have limitations in diagnosis and treatment of intraarticular lesion, and arthroscopic-assisted reduction and internal fixation can be a good alternative. Clinical results of arthroscopic-assisted reduction and internal fixation and open reduction and internal fixation were compared in patients with rubber B and C ankle fracture. The study was conducted retrospectively and targeted 75 patients who underwent surgical treatment from 2016 to 2019, and the inclusion and exclusion criteria are as follows. It was compared by dividing into the following two groups. The clinical score, x-ray, and CT were used to compare the adequacy of reduction and post-traumatic osteoarthritis before operation and during follow-up. Demographic data are as follows, and there was no significant difference between the two groups. There were no significant differences between two groups in pain, foot, and ankle score. There were one case of post-operative deep infection and two cases of superficial infections and six cases of wound problems in open reduction and internal fixation group, but there was no complication in minimal invasive surgery group. There were two cases of obvious advanced post-traumatic arthritis in minimal invasive surgery group and three cases in open reduction and internal fixation group. This case was using arthroscopic-assisted reduction and internal fixation in patients with bimalleolar fracture. First, we made a small incision on lateral malleolar side. We used reduction clamp to make alignment correct and inserted fibular nail. In case of medial malleolar fracture, we used arthroscope to make a correct reduction by watching the fracture sites. After reduction, we used reduction clamp to maintain and we inserted screw in medial malleolar. The surgery was proceeded in minimally invasive method, and in this case, the patient did not experience any complication. There have been studies comparing arthroscopic reduction in internal flexation and open reduction in internal fixation in simple fractures, and although there were no statistically significant difference between the two groups, good results were reported in arthroscopic reduction in clinical scores. In this study, clinical scores in the arthroscopic reduction group also showed better results. The complication rate is reported as high as 50 to 60%, and studies have shown that lower complication rates and early mobility are possible in arthroscopic assisted reduction and internal fixation. In this study, the wound complication rate was lower in the arthroscopic assisted reduction and internal fixation group. In conclusion, in case of Weber B and C type ankle fracture, the arthroscopic assisted minimal invasive surgery can be a good option to lower the wound complication.
