Abstract:
Although the primary imaging modality for the evaluation of inflammatory arthritis of the foot and ankle is currently magnetic resonance imaging, computed tomography may be performed in some patients and can aid in diagnosis. This article reviews a number of inflammatory arthritic conditions that involve the feet. Computed tomographic findings and the role of computed tomography in diagnosing infection, gout, and rheumatoid arthritis of the foot are discussed.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
