The arrows mark the area of a chronic articular  proximal medial plantar fracture of the second phalanx. Note also the abnormal uptake in the dorsolateral aspect of the third phalanx. Both areas were significant in the prognosis.

This six year old TBX filly was found in the field non-weight bearing 2 weeks prior to admission. Upon examination she was 4 of 5 degrees lame in  the left hind at a trot in hand. A low plantar nerve block alleviated the lameness to 3 degrees. Radiographs of the pastern revealed an old medial proximal plantar fracture of the second phalanx.   The fracture line appeared old with healing callous present indicating a chronic articular fracture that may have been re-injured recently.  In addition, elective nuclear scintigraphy revealed marked increased radioisotope uptake in the previously mentioned area as well as a focal area  of uptake along the dorsal lateral aspect of the third phalanx. The owner did not pursue the recommendation for further radiographs.
