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.
