PurposeThe treatment of the posterior fragment in trimalleolar fractures differs from hospital to hospital in the Netherlands. A nationwide survey was performed to evaluate the fixation criteria and practice variation.MethodsAn online cross-sectional survey amongst (orthopaedic) trauma surgeons was performed in the Netherlands. It consisted of three sections: a general section, a section showing preoperative images of six cases and a section with postoperative images of nine cases.ResultsA total of 151 surgeons completed the online survey. 45% of the respondents indicated that they fixated the posterior fragment if smaller than 25% of the intra-articular surface. 48% preferred an open posterior approach to fixate the posterior fragment. There was good consensus in treatment for the two cases with Bartonicek type 4 fractures (operative treatment in 73 and 72% respectively). Little consensus was found for Bartonicek type 2 and 3 fractures (88% opted for operative treatment in one case, but 89% for conservative treatment in the second case). Reoperation was mostly considered in cases with a step-off of more than 1 mm (by 33-38% of the respondents). There was great variation in the choice of treatment if only the size of the posterior fragment was considered. Other fixation criteria such as postoperative step-off or instability after fixation of the lateral and medial malleoli are taken into account. In cases where fixation was needed, a percutaneous approach and an open posterolateral approach were equally preferred.ConclusionsThere is much variation in treatment of the posterior malleolar fracture amongst orthopaedic and trauma surgeons in the Netherlands. The percutaneous approach and open posterolateral approach to fixate the posterior malleolar fracture seem to be equally used in the Netherlands. Still, there is no uniformity in treatment of posterior malleolar fracture, especially for Bartonicek 2 and Bartonicek 3 fractures. Reoperation is considered by less than half of the surgeons in case of postoperative persistent step-off of more than 1 mm.© 2022.
