The most common mechanism that would cause injury to the deltoid ligament is seen in what motion?
Pronation-eversion and pronation-abduction of the ankle
The strongest component of the superficial deltoid ligament is which ligament? (Tibiocalcaneal, tibiosrping, or tibionavicular ligament)
The tibiocalcaneal ligament
The strongest component of the deep deltoid ligament is which ligament? (Anterior tibiotalar or posterior tibiotalar ligament)
The posterior tibiotalar ligament
True or False: impingement syndromes can be seen after inadequate or fibrotic healing of a deltoid ligament post injury?
True. Deltoid ligament injury can lead to scarring and fibrotic changes can manifest as posteromedial impingement; this can present as pain with inversion of the foot. Anteromedial impingement syndrome is associated with lateral ligament injury; this can present as pain with eversion of the foot.
The MRI findings above reveal a complete tear of the deep deltoid ligament, both anterior and posterior components. Other findings in the MRI study included a complete tear of the anterolateral talofibular ligament, a low-grade sprain of the calcaneofibular ligament, marrow oedema in the tip of the lateral malleolus, and a moderate ankle joint effusion.
