Deltoid Ligament
From WikiSM
Contents
Description
- Superficial Ligaments
- Composed of: tibiospring, tibionavicular, superficial posterior tibiotalar, and tibiocalcaneal ligaments
- Tibioligamentous portion has a broad insertion on the Spring Ligament
- Deep Ligaments
- Composed of: deep posterior tibiotalar and deep anterior tibiotalar ligaments
- An intermediate tibiotalar ligament has been described[1]
- Cross only the ankle joint
- Anatomic variance
- Wide variability in cadaveric descriptions[2]
Actions
- Strong restraint which limits talar abduction[3]
- Primary restraint against pronation of the talus[4]
- Superficial ligaments limit talar abduction or negative talar tilt
- Deep layers of the deltoid ligament limit external rotation
