Talocalcaneonavicular joint arthrography for sustentacular-talar tarsal coalitions.

Sustentacular-talar tarsal coalitions can be difficult to detect radiographically. The sustentacular-talar articulation is a part of the talocalcaneonavicular joint. Thus, arthrography of this joint, combined with tangential views of the sustentaculotalar articulation (Harris views), provides a new and simple method to detect or exclude talocalcaneal tarsal coalitions.
