Double-Stacked One-Third Tubular Plating for Suprasyndesmotic Fibula Fractures Technique Description and Clinical Case Series

Fixation for suprasyndesmotic fibula fractures (AO/OTA type 44C, consistent with Weber C) is classically achieved using a single one-third tubular plate. However, these fractures may sometimes require stronger fixation due to the diaphyseal fracture location and the lack of structural support from injured ligaments. To increase stability, 3.5 mm plates can be used, but these plates are bulky and too stiff to contour. As alternative, the authors present the technique and clinical and patient-reported outcomes (PROs) of using stacked one-third tubular plating for suprasyndesmotic fibula fractures to increase stability of fixation. Between 2021 and 2023, 14 patients were treated with stacked one-third tubular plating. All patients healed uneventfully. One patient developed an infection with wound breakdown and exposed hardware after fracture healing. Thirteen patients (93%) responded to PROs. The median Olerud-Molander ankle score was 75 (interquartile range [IQR]: 30-80), the median EQ-5D-5L score was 80 (IQR: 69-81), and the median numeric rating scale (NRS) score was 3 (IQR: 0-5). The use of double-stacked one-third tubular plates is a simple and safe technique that can be used to increase stability of suprasyndesmotic fibula fractures leading to reliable healing rates and satisfactory PROs.<b>Levels of Evidence:</b> <i>Level IV Retrospective Case Series</i>.
