Pain TENDONS: There is a small amount of fluid within the tendon sheath of the flexor hallucis longus which may reflect a mild tenosynovitis or fluid extension from the joint. The flexor and extensor tendons appear intact. The peroneal tendons appear intact. There is minimal linear intermediate signal intensity within the distal fibers of the Achilles tendon which may represent a mild tendinosis.LIGAMENTS: The lateral collateral ligament complex appears intact. The distal tibiofibular syndesmotic complex appears intact. The imaged components of the deltoid ligament appear intact. There is, however, increased signal abnormality on fluid sensitive sequences within the posterior talofibular ligament likely reflecting edema.ARTICULAR SURFACES AND BONE: Note is made of an os trigonum. There is increased bone marrow signal abnormality within the os trigonum as well as within the posterior aspect of the body of the talus. No additional bone marrow signal abnormalities identified. Fluid extends from the tibiotalar joint cephalad into the posterior subtalar recess in the surrounding area. ADDITIONAL
Findings indicating os trigonum syndrome as described above. Other findings as described.
