39-year-old female with persistent pain status post sprain TENDONS: There is perhaps mild tendinosis of the peroneus brevis as it courses below the fibular tip, although this is equivocal. Otherwise the peroneus tendons are intact. The tendons of the achilles, tibialis posterior, flexor digitorum longus, flexor hallucis longus, tibialis anterior, extensor hallucis longus, and extensor digitorum longus are grossly intact. LIGAMENTS: A marker was placed along the lateral aspect of the ankle. The anterior talofibular ligament is thickened and poorly defined compatible with prior tear. Its attachment to the talus is also poorly defined. The calcaneofibular ligament is also thickened indicating a sprain. The posterior talofibular ligament is grossly intact. The distal tibiofibular ligament complex is grossly intact. The deep fibers of the deltoid ligament have lost some of their normal striations suggesting prior sprain. ARTICULAR SURFACES AND BONE: Small amount of fluid in the tibiotalar joint which is probably within normal limits. We see no osteochondral defect. Small amount of fluid within the recesses of the subtalar joint is also within normal limits. Tiny osteophytes at the talonavicular joint suggesting mild osteoarthritis.
Findings compatible with prior tear of the anterior talofibular ligament and sprain of the calcaneofibular ligament.
