Functional outcome of comminuted upper metaphyseal tibial fracture treated with circular external fixators

Abstract

<p class="abstract"><strong>Background:</strong> High speed motor vehicle accidents are on the rise over the past few years. These are responsible for most of the complex fractures of the tibial metaphysic. Proper treatment of these fractures is of paramount importance. The use of circular fixators for the definitive treatment of such fractures entails a minimally invasive technique of insertion that gives good fracture reduction and stability combined with minimal postoperative complications.</p><p class="abstract"><strong>Methods:</strong> This study was prospective and conducted over 22 patients diagnosed with upper comminuted metaphyseal tibial fracture treated with circular external fixator.</p><p class="abstract"><strong>Results:</strong> In this series, all 22 patients (100%) were male. Fourteen cases (64%) involved the left tibia and eight (36%) fractures were on right. The mean patient age was 49.5 years (range 26-75). Road traffic collisions accounted for most of the injuries (n=14), while fall from bike (n=8). In this study, using knee society score evaluation, excellent results (KSS>80) were seen in 8 patients (36.36%), good results (KSS 70-79) were seen in 10 patients (45.45%), fair (KSS 60-69) in 4 patient (18.18%) and poor (KSS< 60) in 0 patient (0%). Complication seen was pin tract infection in 2 patients (9.9%), which was managed by regular pin site dressings. Another complication was non-union in 1 patient (4.54%). No other complication was encountered.</p><p class="abstract"><strong>Conclusions:</strong> Circular external fixation is a promising modality for surgical treatment of comminuted upper metaphyseal tibial fractures. It allows satisfactory realignment of the fractured fragments and their stabilization, besides early mobilization of the joints and care of associated soft tissue injuries, without significant complications.</p>
