In May of 2014, a dark mass was identified inside Sintar’s hoof. The vet diagnosed it as a keratoma in need of immediate removal. Following the surgery Sintar was on stall rest with limited hand walking only, the recommended protocol for keratoma surgeries. In late October, Sintar was still lame. Further radiographs showed that the entire keratoma had not been removed. A second, more aggressive surgery took place (see photo A).
