Purpose: Demonstrate talar articular surface of calcaneus and anterior subtalar joint. This method provides a clear view of the lateral aspect of the calcaneus and is useful for evaluating fractures and arthritic changes.
Developmental Talocalcaneal Coalitions and Associated Conditions
The talocalcaneonavicular joint, sometimes designated the anterior subtalar joint, is comprised of the concave talar facet on the posterior surface of the navicular bone and four talocalcaneal facets: the concave middle and anterior facets of the calcaneus and the apposing middle and anterior facets of the talus.
A radiological classification system for talocalcaneal coalition …
2013年7月24日 · Based on the cartilaginous or bony nature, facet joint orientation and bony structure morphology, we classified talocalcaneal coalitions into four types: I (linear with or without posterior hooking), II (talar overgrowth), III (calcaneal overgrowth) and IV (complete osseous).
Fibrous coalitions, particularly extra-articular talo-calcaneal coali-tions, may have cross-sectional imaging findings that resemble normal anatomic variants, particularly the medial talo-calcaneal ligament and to a lesser extent the presence of an accessory articular facet between the posterior margin of the sustentaculum and postero-medial pro...
