51-year-old male with pain/avulsion fracture TENDONS: Slight undulation in the Achilles tendon related to retraction. Otherwise the tendon is unremarkable. Mild edema adjacent to the Achilles tendon posteriorly may represent paratenonitis. The remaining tendons are unremarkable.LIGAMENTS: The lateral collateral ligament complex is intact. Distal tibiofibular syndesmotic complex appears intact. Loss of fatty striation in the deltoid ligament with increased signal intensity is compatible with a sprain. Mild edema along the plantar fascia is of questionable clinical significance.ARTICULAR SURFACES AND BONE: As seen on the prior radiograph, there is an avulsion type fracture of the superior aspect of the calcaneus. Edema in the underlying calcaneus presumably represents hemorrhage. Mild osteoarthritis affects the ankle and midfoot.ADDITIONAL
Avulsion-type fracture of the superior aspect of the calcaneus and other findings as described above. The Achilles tendon itself is unremarkable.
