Document Type



A two year old Quarter Horse gelding presented for evaluation of a previous vague lameness in the left hind leg. The horse was not lame at presentation. A radiographic survey of the tarsal and metatarsal region was made.The lateral-medial view shows a linear radiolucency coursing 'from proximal to distal within the dorsal cortex of metatarsal three (MT3) at the junction of its proximal and rniddle thirds. This lucency is identified as a vertically oriented line in the dorsoplantar view. At the endosteal level there is a slight bulging effect to the endosteal contour, but the margin is distinct. Additional oblique views and bright light viewing did not reveal associated soft tissue swelling or periosteal new bone. It is noted that the typical nutrient foramen is absent in the plantar cortex.
