Talar osteochondral defect

Case contributed by Dr Jeremy Jones

Presentation

Jumped from wall 3 weeks ago. Painful when walking. Concern for fracture or calcaneal injury.

Patient Data

Gender: Male
Modality: X-ray

Depression of the lateral aspect of the right talar dome with a fragment of bone within.

Case Discussion

Following microtrauma to the bone surface, damage to the cartilage and adjacent subchondral bone result in a lucent defect in the surface of the affected bone.  Knees and ankles are commonly affected, usually following trauma.

Because these injuries can often be subtle, they are not infrequently missed by A&E doctors.  It's a helpful addition to any ankle checklist.
