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

Video Transcription

Video Summary

The video discusses the biomechanical role of the deltoid ligament in ankle stability and the efficacy of surgical repair and augmentation. The deltoid ligament, located on the medial side of the ankle, connects the medial malleolus to multiple bones. The ligament is frequently ruptured in ankle fractures. The study used 10 cadaveric specimens and performed biomechanical testing in different states, including native, anterior and posterior deltoid cuts, repairs, and augmentations. Results showed that complete deltoid tears caused major instability, while anterior repairs with tibial calcaneal augmentation were the most effective treatment. An anterior deltoid tear alone showed increased but manageable instability.
