Patient came in today. Soccer player injured his ankle on the weekend. Jumped for a header and landed on someone’s foot rolling his ankle. His history included an old ATFL tear years ago. He localised his pain to the high ankle region, and I thought you beauty syndesmosis here we go.
He had a normal plain x-ray. On ultrasound a moderate ankle joint effusion, ATFL torn as previously noted, but an intact AITFL. Superior to AITFL it was oedemas, with some joint widening on stress. Patient’s pain was located right on this. I read in literature the AITFL can be made of of more than one ligament or an accessory ligament. Could this be a ligament tear or is it part of the interosseous membrane. Or am I missing something else?
