Overview

The tibiofibular syndesmosis is disrupted in approximately 10–20% of ankle fracture cases and requires repair.1,3 For decades, screw fixation of the syndesmosis has been the gold standard for treatment.1 However, emerging clinical evidence has demonstrated that flexible, suture-based syndesmosis repairs have successful clinical outcomes and may reduce complications associated with malreduction of the syndesmosis when fixed with screws.2,3,4

Designed in conjunction with Alastair Younger, MB, Ch.B., M.Sc., Ch.M., FRCS(C); Selene Parekh, MD, MBA; and Steven Morgan, MD, the Acu-Sinch Knotless Implant enables the dynamic stabilization of laxity or syndesmotic disruptions to the tibiofibular joint.

The Acu-Sinch Knotless buttons may be augmented with a washer or may be used in conjunction with the Acumed and OsteoMed® fibula fracture fixation plates and intramedullary nails with 3.5 mm nonlocking screw holes. Our patent pending release mechanism gives the user control to place the medial button subcutaneously without the need for direct visualization.
