What is subtalar arthroereisis?
Subtalar arthroereisis or extraosseous talotarsal stabilization (EOTTS) is performed by placing an implant in the sinus tarsi (a canal located between the talus and the calcaneus) and is designed to correct excessive talar displacement and calcaneal eversion.
What is subtalar distraction?
In contrast to fusion as a salvage procedure, subtalar distraction arthroplasty allows the possibility of maintaining the function of the arthritic subtalar joint while reducing pain and improving the overall function of the foot and ankle.
What is subtalar synovitis?
The subtalar joint synovitis, which is responsible for chronic inflammation and infiltration of fibrotic tissues in the sinus tarsi, results in ankle pain.
What is the subtalar?
The subtalar joint is a joint in your hindfoot where two tarsal (ankle bones) are joined by the interosseous talocalcaneal ligament. The two bones that make up this joint are the talus bone, located in the curve of your ankle, and the calcaneous bone, which forms your heel.
What is subtalar coalition?
Talocalcaneal coalition or peroneal spastic foot or subtalar coalition is an anomalous connection between the talus and the calcaneum that can present with painful and rigid flat-foot in older children and adolescents. The talocalcaneal coalition is part of a spectrum of tarsal coalitions that causes rigid flat foot.
What is subtalar joint?
Subtalar joint is made up of articulation between three joint surfaces inferiorly talus with three joint surfaces superiorly calcaneus (Fig. 23.14) (Drake et al., 2015; Bartonicek et al., 2018). Subtalar joint functions as a bridge between foot and ankle; transferring loads from foot to tibia or from tibia to foot.
Where is the subtalar?
rearfoot
The subtalar joint is located within the rearfoot (see Fig. 11.1). This joint consists of the articulation between the facets on the inferior surface of the talus and the matching facets on the superior surface of the calcaneus.
What is posterior subtalar joint?
The subtalar joint (talocalcaneal joint) is anatomically described as the articulation formed between posterior articular surfaces of two tarsal bones; the talus and calcaneus. In the literature, this joint is also referred to as the anatomical subtalar joint or subtalar joint proper.
