CT Arthrogram of my Ankle 2 April 2009

•Indication: Previous talar body fracture. Anterolateral impingement? Increasing secondary to bony spur.
•Technique: With local anaesthetic and fluoroscopic guidance, contrast mixture (Omnipaque, normal Saline, Xylocaine and Adrenaline) was injected into the tibiolar joint. Helical scans were then performed through the ankle with sagittal coronal and axial reformats. The patient was given standard postarthrogram instructions.
•Findings: There is a band of sclerosis at the site of the previous fracture of the body of the talus. A small residual cortical deformity is present at the dorsal aspect of the talar neck. This is less prominent than on the CT of 3.8.2007. A small (4 x 5mm) full thickness defect is present in the articular cartilage at the lateral margin of the talar dome. The subchondral cyst formation associated with this has increased slightly. The subchondral cysts at the anterior margin of the tibial plafond and in the medial aspect of the talus anteriorly are slightly less prominent. There is spurring at the anterior margins of the tibiolar joint medially which may be causing impingement. The spurring has not altered significantly from the previous CT.

There is a moderately large os trigonum. A small amount of cystic change is present within the ossicle adjacent to the synchondrosis. The subtalar and midfoot joints are normal in appearance.
•Impression: Small osteochondral lesion lateral talar dome. Mild degenerative changes in the ankle joint with spurring anteromedially.
