In general, the talocalcaneal joint
, a major synovial subtalarjoint, is functionally important for ankle movements such as in version and eversion of the foot.
Anterior to this non-articular part is articular which articulates with talus bone to form talocalcaneal joint
, where inversion and eversion of foot occurs.
The whole middle facet of the talocalcaneal joint
was involved (Fig.
Non-osseus coalitions are commonly seen at the talocalcaneal joint
or calcaneonavicular joint.
Osseous and non-osseous coalition of the middle facet of the talocalcaneal joint
. J Bone and Joint Surgery (Am).
Its inferolateral surface comprises a portion of the posterior facet of the talocalcaneal joint
, while its superolateral surface articulates with the lateral malleolus.
Talocrural and talocalcaneal joint
kinematics and kinetics during the stance phase of walking.
Forces that can influence talocalcaneal joint
are calcaneofibular ligament, the superior peroneal retinaculum (calcaneal fibular retinaculum), the peroneal tendon sheaths, and the posterior talocalcaneal ligament.
Anatomically, the facets of superior articular surface (anterior, middle, and posterior) of calcanei articulate with the head of overlying talus to form a subtalar joint which is called "the talocalcaneal joint
Coalition of the middle talocalcaneal joint
is second only to calcaneonavicular coalition.
The most common imaging feature of PAIS in this series was high T2 signal posterior to the talocalcaneal joint
, indicating synovitis (n = 25).
Inversion and eversion occur along the anteroposterior (AP) axis in the subtalar joint (talocalcaneal joint
