Posterior Tibiotalar Ligament

From WikiSM

Description

  • Deltoid ligament complex including the posterior tibiotalar ligament[1]
    Deltoid ligament complex including the posterior tibiotalar ligament[1]
  • The branches of the deltoid ligament of the ankle, including the posterior tibiotalar ligament[2]
    The branches of the deltoid ligament of the ankle, including the posterior tibiotalar ligament[2]
  • Normal posterior tibiotalar ligament demonstrated on coronal (A) and axial (B) proton density-weighted MR images. Note the normal multifascicular appearance.[3]

Anatomic illustration of the deltoid ligament and other medial ligaments of the foot and ankle
Ultrasound image of the superficial posterior tibiotalar ligament. A, Position of the patient and the probe. B, The thin tract of the ligament (yellow arrows) extends from the tibia to the posteromedial tubercle of the talus, partial overlap to the deep posterior tibiotalar ligament (dPTL). It can be seen that the fibers reach the channel of the flexor hallucis longus (FHL) tendon on which the artery (A), veins (V), and posterior tibial nerve (PTN) are located. Superficial to the ligament are the tibialis posterior (TP) tendon, the flexor digitorum longus (FDL) tendon, and the flexor retinaculum (white arrows).[5]

Other Names

  • Superficial Posterior Tibiotalar Ligament
  • SPTTL
  • Posterior Tibiotalar Ligament of the Deltoid Ligament
  • Posterior Tibiotalar Portion of the Deltoid Ligament
  • Posterior Deltoid Ligament
  • Posterior Tibiotalar Band
  • Posteromedial Tibiotalar Ligament

General

Gross Anatomy

Attachments

  • Origin: adjacent to distal center of intercollicular groove of the medial malleolus.
  • Insertion: posteroinferior medial talar body

Anatomic Variants
