J. C. Gasiorowski, L. M. Getman, D. W. Richardson Equine Veterinary Education October 2011 23 10 489-493 Two competitive horses were presented for examination of chronic lameness; one associated with a hoof-wall deformity, the other with a firm mass over the dorsal pastern region. Radiographs revealed moderately radiopaque masses associated with both deformities. The lesions were characterised ultrasonographically as noninvasive, well-circumscribed heterogeneous masses. Computed tomographic examination of the second case revealed a well-defined, partially mineralised, bi-lobed mass with associated bony resorption of the underlying middle phalanx. Both patients were anaesthetised and the keratomas surgically removed via approaches 1–2 cm proximal to the coronary bands. Both horses were stall-sound 2 days after surgery and returned successfully to an equal level of competition by 8 months. A supracoronary approach is a viable alternative to partial or complete hoof wall resection for the removal of nonsolar keratomas from the foot of a horse.
