Case contributed by Dr Shailaja Muniraju

Presentation

History of trauma 2 days back.

Patient Data

Age: 35 years
Gender: Male
MRI

The proximal pole of the capitate shows focal areas of marrow edema, in keeping with a bony bruise/microfracture.

Minimal joint effusion seen in the peri-scaphoid and peri-triquetrum joint space, furthermore, this effusion is seen to engulf the channel around the capitate.

The carpal joint spaces shows normal parallelism and symmetry with normal carpal arcs. No features of instability.

Subcutaneous plane shows mild edema changes.

Complementary CT screening confirmed the above MRI findings with superior bony details.

Special thanks: Dr. H.K Anand

There is a definitive cortical breach across the proximal pole of capitate, in keeping with microfracture.
