57-year-old male with lateral ankle pain, episodic effusions x3 months. Evaluate for occult fracture or osteochondral defect. TENDONS: The Achilles tendon is within normal limits. The flexor tendons appear intact. The peroneal tendons appear intact. The extensor tendons are within normal limits.LIGAMENTS: The lateral collateral ligament complex is intact. The distal tibiofibular syndesmotic complex appears intact. There is loss of the normal fatty striation in the deep fibers of the deltoid ligament which may represent an old sprain.ARTICULAR SURFACES AND BONE: There is a nondisplaced fracture through the anterior process of the calcaneus with edema within the adjacent bone marrow. There is mild edema within the medial aspect of the cuboid that may represent a contusion. There is a subchondral focus of decreased signal intensity within the cuboid, beneath the anterior process of the calcaneus, which could conceivably represent a nondisplaced impaction fracture, but this is equivocal. There are small foci of signal abnormality within the lateral cuneiform and base of the third metatarsal which are likely degenerative in etiology. ADDITIONAL
Nondisplaced fracture through the anterior process of the calcaneus and other findings as described above.
