13-year-old American Paint Horse gelding
Presented for left thoracic limb lameness and recurrent hoof abscess
section content
- Smooth, well marginated focal radiolucent defect in palmar medial aspect of P3 solar margin best seen on DMPaLO
- Mild flattening on DPA on medial aspect of P3
- Keratoma is most likely differential
- Focal osteomyelitis less acceptable as the smooth defect is more consistent with pressure atrophy
- Surgery is indicated
In general, candidates did well with this case. Full credit was given if keratoma was the first (or only) differential. Candidates lost points if focal osteomyelitis/pedal osteitis was listed as the first differential, and lost more points if keratoma was not mentioned.
