Is the sustentaculum tali on the calcaneus?
The sustentaculum tali is on the plantaromedial aspect of the calcaneus. Injuries involving the medial aspect of the hock often involve the sustentaculum tali and adjacent tarsal sheath. Ultrasonography is useful to assess the deep digital flexor tendon (DDFT) and tarsal sheath.
Where is the sustentaculum tali located?
the calcaneus
ANATOMY. The sustentaculum tali is a triangular projection found on the medial surface of the calcaneus, with its base facing posteriorly and apex (Fig 3a) anteriorly. The superior surface contains the middle calcaneal facet.
What is the function of the sustentaculum tali?
Anatomical Parts At the upper and forepart of the medial surface of the calcaneus is a horizontal eminence, the sustentaculum tali, which gives attachment to a slip of the tendon of the Tibialis posterior.
What ligament attaches to the sustentaculum tali?
Anatomy. The spring ligament fills the gap between the calcaneus and the navicular bone, it attaches from the sustentaculum tali of the calcaneus to the medial-plantar surface of the navicular.
Is the sustentaculum tali medial or lateral?
Toward the upper and anterior end is a medially oriented horizontal projection, the sustentaculum tali (see the second image below). The sustentaculum tali has an articular surface for the middle calcaneal facet and is grooved inferiorly to house the flexor hallucis longus tendon.
What is the function of the sustentaculum tali quizlet?
At the upper and forepart of the medial surface of the calcaneus is a horizontal eminence, the sustentaculum tali (alternatively, the talar shelf), which gives attachment to the plantar calcaneo-navicular (spring) ligament, tibiocalcaneal ligament, and medial talocalcaneal ligament.
What does Sustentaculum mean?
Medical Definition of sustentaculum : a body part that supports or suspends another organ or part.
Does the sustentaculum tali support the talus?
The malformed sustentaculum tali is unable to support the head of the talus, and superimposed body weight allows the talus to adduct and plantar flex while the calcaneus simultaneously everts.
What bone is supported by the sustentaculum tali?
The sustentaculum tali is a horizontal shelf that arises from the anteromedial portion of the calcaneus. The superior surface is concave and articulates with the middle calcaneal surface of the talus. The inferior surface has a groove for the tendon of flexor hallucis longus.

Which ligament is also referred to as the “spring” ligament? Plantar calcaneonavicular ligament. Which of the following is true regarding the metatarsal arch? The first metatarsal head bears 33% of the body’s weight during normal gait.
What is the talar shelf?
On the medial side of the base of the calcaneal tuberosity is the sustentaculum tali (talar shelf), a shelf like process that overlaps the plantar aspect of talus and supports the deep digital flexor tendon. On the plantar side of the sustentaculum tali is the groove for tendon of flechissor digitorum lateralis.
What is the sustentaculum tali of the calcaneus?
Abstract Background: The sustentaculum tali of the calcaneus is a vital load-bearing structure. Isolated sustentacular fractures are rare and may have implications for future hindfoot function.
Are there any fractures of the sustentaculum tali?
Fractures of the sustentaculum tali are rare injuries associated with high energy mechanisms, and associated ipsilateral foot injuries are common. Open reduction and internal fixation of these fractures was reliable and possible through a medial approach involving distal retraction of the digital fl …

Sustentaculum Tali Location. It is present on the medial side of the calcaneus. This portion of the heel bone shows a prominent and console-shaped protrusion supported on the medial surface of the calcaneus.
Where does the name sustentaculum tali come from?
