Deltoid Ligament: Functional Analysis of the Medial Collateral Ligamentous Apparatus of the Ankle Joint

Dynamic Stress Testing Is Unnecessary for Unimalleolar Supination-External Rotation Ankle Fractures with Minimal Fracture Displacement on Lateral Radiographs

“…The deltoid ligament and its bony insertion (medial malleolus) are considered the main stabilizers of the ankle mortise (8,9). A displacement of a fibular fracture is thought to be of minor importance in this stability (6).…”

Medial Collateral Ligament Complex of the Ankle: MR Appearance in Asymptomatic Subjects

“…T he medial collateral ligament (MCL) of the ankle-also called deltoid ligament-is a strong ligamentous complex with various components (1)(2)(3)(4)(5)(6)(7). Although descriptions vary widely, there is general agreement that the MCL consists of a deep layer that courses from the medial malleolus to the talus and of a deltashaped superficial layer that courses from the medial malleolus to the navicular, the spring ligament, and the calcaneus.…”

The Anatomy and Function of the Deltoid Ligament

“…It has been shown that the loss of TNL and TSL leads to a measurable increase in eversion/pronation without any tilting of the talus or subtalar gapping. [17][18][19][20] It has also been shown that the loss of the TNL and the TSL allows the occurrence of an increase in internal rotation of the leg. In fact, the loss of the TNL and TSL restraint unlocks the subtalar joint, allowing further eversion/pronation.…”

“…Grath 17 confirmed these findings in a similar experiment. Rasmussen and colleagues 18,19 investigated the function of various parts of the deltoid ligament and stated that the superficial layers of the …”
