Arthrography of the metatarsophalangeal joint.

Arthrography has been an extremely useful tool in the diagnosis of various intra-articular disorders of multiple joints. To date, little has been written regarding the technique and value of arthrography of the metatarsophalangeal (MTP) joints of the foot. The purpose of this paper is to briefly describe the technique, demonstrate a normal arthrogram of the MTP joint, and provide case descriptions in which arthrography has been useful in diagnosis of intra-articular problems related to the MTP joint.
