Abstract
IntroductionBimalleolar fractures represent 9% of fractures and affect 187/100,000 people per year. The gold standard for osteosynthesis is a one-third tubular or lateral locking plate and compression screwing or use of tension band wiring, with complete weight bearing planned around the 6th week. The development of locking plates seems to allow earlier resumption of weight bearing. The objective of our study was to evaluate the clinical and radiological results after internal fixation of bimalleolar fractures using locking plates with complete weight bearing authorized from the outset. The hypothesis was that this does not predispose to cutaneous or mechanical complications. Hardware and methodA continuous multi-operator retrospective study was performed. The clinical and radiological data of 55 patients operated on for bimalleolar fractures were collected. All underwent osteosynthesis with medial and lateral locking plates with authorization for weight bearing from the outset. ResultsComplete weight bearing was resumed at 27.4 days 14.7 [7–60] postoperatively. No non-union or malunion was found. Two patients presented with delayed medial healing without the need for hardware removal. Two patients required removal of the lateral Plate 1 month postoperatively due to infection. Seven patients presented with discomfort related to hardware, justifying its removal at 1 year. The Kitaoka score at 1 year was 94.6 7.7 [71-100]. ConclusionThe use of medial and lateral locking plates in bimalleolar fractures associated with complete weight bearing authorized from the outset allows complete consolidation. There was no increase in cutaneous or mechanical complications. Level of evidenceIV, retrospective study.
