The Biomechanical Role of the Deltoid Ligament on Ankle Stability: Injury, Repair and Augmentation

Video Transcription

Video Summary

In this video, Alex Brady from the Stedman-Philpon Research Institute discusses the biomechanical role of the deltoid ligament in ankle stability. The deltoid ligament is frequently injured in ankle fractures and syndesmotic injuries. The current practice is conservative treatment, but poor outcomes have been observed. The purpose of the study was to determine the biomechanical role of the deltoid ligament and the efficacy of different repair methods. The study used cadaveric specimens and tested them in various states, including native, repaired, and augmented. The results showed that a complete deltoid tear caused major instability, highlighting the importance of repair. The optimal treatment for a complete tear was an anterior repair with tibial calcaneal and tibial tailor augmentation. In the case of an anterior deltoid tear only, surgical treatment with an anterior repair and tibial calcaneal augmentation was found to be the best option.
