- W2033335200 abstract "Background: There remains no consensus regarding the role of computed tomography (CT) scans in preoperative planning for malleolar ankle fractures. The aim of this study was to determine the role of preoperative CT scans on operative planning in these fractures. Methods: A retrospective analysis was performed on 100 consecutive patients treated at our institution for malleolar ankle fractures (AO type 44) with both preoperative radiographs and CT scans. Six study participants reviewed available radiographs and formulated an operative (or nonoperative) plan including positioning, operative approach, and fixation. Participants then analyzed CT scans of the same fractures, deciding whether (and how) they would alter operative strategy. Characteristics of fractures and radiographs were correlated with changes in operative strategy. Results: Operative strategy was notably changed in 24% of cases after CT review, with strong intraclass correlation (0.733). Common changes included alterations in medial malleolar (21%) or posterior malleolar (15%) fixation and fixation of an occult anterolateral plafond fracture (9%). Notable predictors of changes in operative strategy included trimalleolar over unimalleolar fractures (29% vs 10% rate of change), preoperative dislocation over no dislocation (31% vs 20%), the presence of only radiographs with overlying plaster versus fractures with at least 1 set of radiographs without plaster (25% vs 14%), and suprasyndesmotic versus trans- and infra-syndesmotic fractures (40% vs 20% and 4%, respectively). Conclusions: CT scans may be useful adjuncts in preoperative planning for malleolar ankle fractures, most notably in fracture dislocations, cases in which all available radiographs are obscured by plaster, trimalleolar fractures, and suprasyndesmotic fractures. Level of Evidence: Level III, retrospective comparative study." @default.
