Deltoid Ligament

From WikiSM

Description

Anatomic illustration of the deltoid ligament and other medial ligaments of the foot and ankle
The branches of the deltoid ligament of the ankle[1]
Deltoid ligament complex . ( A ) The deep layer of the deltoid ligament complex consists of the aTTL and the pTTL. ( B ) The superficial layer consists of the TNL, TSL, and TCL. The TSL, which is often the only visible superficial deltoid component, converges with the superomedial calcaneonavicular ligament (smCNL) component of the spring ligament complex at the level of the sustentaculum tali of the calcaneus. ( C ) Coronal illustration (illustrated by Salvador Beltran) showing the superficial ( solid arrow ) and deep ( dashed arrow ) layers of the deltoid ligament complex.[2]

Other Names

  • Deltoid Ligament
  • Medial Ankle Ligament
  • Deltoid Ligament Complex

General

  • Stabilizer of medial Ankle

Superficial Ligaments

Deep Ligaments

Anatomic variance

  • Wide variability in cadaveric descriptions[4]

Actions

  • Strong restraint which limits talar abduction[5]
  • Primary restraint against pronation of the talus[6]
  • Superficial ligaments limit talar abduction or negative talar tilt
  • Deep layers of the deltoid ligament limit external rotation
