Temporary bridging external fixation in distal tibial fracture

Fractures that involve the distal area of the tibia are associated with a high percentage of complications. Soft tissue oedema, swelling, blisters, skin abrasions and open wounds could compromise the outcome of these lesions. The waiting time before surgery with ORIF is mostly due to soft tissue conditions. Early application of a simple joint-spanning external fixator would achieve the initial goal of stability and the respect of soft tissue, thereby decreasing the time necessary for definitive treatment.A total of 40 consecutive patients (22 male and 18 female) with a mean age of 52 years (range 17–82 years) with distal tibial fracture treated between January 2010 and January 2013 were evaluated. Early temporary external fixation was the first treatment step. Twenty patients had pilon fractures, characterised by the intra-articular involvement of the distal tibia with metaphyseal extension, and 20 patients had malleolar fracture-dislocation.Patients were divided into two groups, A and B. Group A comprised 10 patients with ankle fracture-dislocation and bone fragmentation, who were treated with a temporary bridging external fixation that was maintained after ORIF to exploit ligamentotaxis during the first phases of bone healing.In Group B (30 patients), the external fixation was removed after ORIF.The results of the study are in line with the recent literature: temporary external fixation in high-energy trauma and fracture-dislocation of the ankle enables soft tissue to be restored, which facilitates postoperative assessment of bone fragments by CT scan. The complication rate in this study was 5% in patients with malleolar fractures and 20% in patients with pilon fractures.The maintenance of temporary external fixation after ORIF synthesis during the entire first stage of bone healing seems to be a good method of treatment that has a low rate of soft tissue complications.
