PERONEAL tenography, a radiological procedure, permits direct evaluation of peroneal tendon entrapment or displacement, as well as strong indirect evidence of calcaneofibular ligament tears. Although it has been described chiefly in the orthopedic literature previously, peroneal tenography is being requested of radiologists with increasing frequency. Our purpose is to describe the procedure and to present examples of the normal and abnormal findings that may be encountered.
Peroneal tenography provides anatomic definition of the peroneal tendons and their relationships to the lateral malleolus, calcaneus, and the lateral ligamentous structures of the ankle.The most common long-term complaints following fracture of the calcaneus are stiffness and inability to control the foot and ankle.1 This inability results frequently in twisting or spraining the foot and ankle, as the patient is unable to resist the turning in (inversion) of the foot, particularly on irregular surfaces. Anatomically, this disability can be ascribed to
