Tibiocalcaneal ligament

Last revised by Dr Joachim Feger on 17 Sep 2021

The tibiocalcaneal ligament belongs to the medial supporting structures of the ankle and is one of the four superficial components of the deltoid ligament 1-3.

The tibiocalcaneal ligament is located superficial to the deep posterior tibiotalar ligament, posterior to the tibiospring ligament, and anterior to the superficial part of the posterior tibiotalar ligament. It courses almost vertically from the medial tibial malleolus to the posterior sustentaculum calcanei 1,2. The tibiocalcaneal ligament becomes tenser with pronation and dorsiflexion 3.

Proximally the tibiocalcaneal ligament inserts near the intercollicular groove of the medial malleolus.

Distally it inserts at the posterior part of the sustentaculum tali, just posterior to the proximal origin of the superomedial portion of the calcaneonavicular ligament.

Depending on the study it was reported to be absent in 21-50% of the cases 1,2.
