This case report describes the clinical, radiographic,
computed tomographic and post mortem findings in 2
foals with severe bilateral physitis of the distal third
metatarsal bones (Mt3). The foals were admitted because
of bilateral hindlimb lameness of several weeks duration.
Initial examination revealed that the physeal regions of the
distal Mt3 were enlarged, warmer than normal and painful
on palpation. Case 1 was treated conservatively and
discharged but was readmitted 8 weeks later because of
clinical deterioration. In both foals, radiographs showed
plantar dislocation of both epiphyses through the physis
and a Salter-Harris type 1 fracture. The foals were
subjected to euthanasia and a post mortem examination.
