We aimed to evaluate functional outcomes of SAD type 2 bimalleolar fractures in comparison to supination\u2013external rotation (SER) type 4 fractures.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Methods:<\/jats:bold>\n                    We retrospectively reviewed data of 42 cases with SER type 4 and 20 cases with SAD type 2 injuries. Patients with a history of rheumatic disease, open fractures, pathologic fractures, nonbimalleolar fractures, neuropathic disease, and talus osteochondral lesion, and those operated on after greater than 72 hours because of skin lesion or managed with a two-stage surgical protocol after external fixation, were not included in the study. We compared these two groups in terms of the mean age, follow-up time, visual analog scale pain and American Orthopedic Foot and Ankle Society scores, Kellgren-Lawrence arthrosis classification, union time, and complications.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    The groups did not differ in terms of mean age (\n                    <jats:italic>P<\/jats:italic>\n                    = .115) and sex (\n                    <jats:italic>P<\/jats:italic>\n                    = .573).
