Technical Tip: Fixation of Medial Malleolar Fractures Using a Suture Anchor

摘要

The ankle joint is stabilized by both bone and ligamentous components. Studies have shown injury to the medial structures allows the talus to displace laterally. Anatomical fixation of the medial malleolus fracture helps restore stability to the ankle mortise.3 The conventional technique for medial malleolar fracture fixation is using partially threaded cancel-lous screws with or without a washer.4 Alternatively, if the distal component of the fracture is small, a tension band wire technique may be used.1'2 This method of fixation can be technically demanding with small fragments. There is the potential to fragment the distal component and lose stable fixation. Later there can be secondary problems from prominent hardware, leading to further surgery. We describe an alternative technique for fixation of medial malleolar fractures using two sutures passing through a titanium anchor (TWINFIX Ti 5.0mm Suture Anchor with two No. 2 ULTRABRAID sutures, Smith & Nephew, Andover, MA) (Figures 1 and 2).
