The Harris projection (also called the penetrated axial projection) is a special radiographic view that is used for assessment of talocalcaneal coalition.
Radiography
The patient stands on the cassette and the x-ray beam is angled between 35 and 45 degrees.
Radiographic features
The talocalcaneal joint is exposed with the posterior facet laterally and the sustentacular facet medially.
