Chiang CC, et al. - Researchers report an algorithm for arthroscopic reduction and minimally invasive surgery (ARMIS), as well as compared it with standard open reduction–internal fixation (ORIF), in terms of surgical outcomes, for the treatment of supination–external rotation (SER) ankle fractures. The algorithm described for ARMIS included minimally invasive plating for lateral malleolar fractures first, followed by ankle arthroscopy for detection of syndesmotic injuries and then arthroscopic reduction of medial malleolar fractures or mini-open repair of the deltoid ligament. Radiographic measurements of talocrural angle, fibular length, tibiomedial malleolar angle, medial clear space, and tibiofibular clear space were obtained. Based on the findings, the possible safety, reliability, as well as efficacy of this algorithm and the ARMIS techniques was suggested in the treatment of SER fractures. The benefits of ARMIS included the achievement of promising surgical outcomes and less early postoperative pain, a shorter postoperative stay, and lower incidences of complications and reoperations than ORIF. However, ARMIS techniques were associated with longer operative time and higher irradiation dose.
