Tenography around the ankle and introduction of a new technique.

Tenography; the injection of radiopaque contrast medium into a tendon sheath, is being done with increasing frequency for diagnosis of painful conditions surrounding the ankle because it provides a permanent radiographic record of the extent of soft tissue pathology. The authors discuss the indication for tenography, the precautions that are necessary, and the techniques used to introduce the contrast material. They advocate a technique that greatly improves the accuracy of sheath penetration.
