Plain-English summary
A Quarter horse filly had a wound on her right hind leg that was caused when her mother stepped on her. After surgery to clean the wound, the filly developed a problem with her left hind leg that caused it to bend inward, which was fixed with a special screw. However, further X-rays showed that both her left and right hind legs had a serious joint issue called talocalcaneal subluxation (where the bones in the ankle are not aligned properly). Since there was no information on how to treat this condition, the decision was made to humanely euthanize her. Later, the same owner brought in a two-month-old colt from the same mare for a routine check-up, and X-rays revealed that he also had the same joint issue, even though he had not shown any signs of trauma.
Abstract
A Quarter horse filly was evaluated for a two-week old wound of the right hind cannon bone after the mare stepped on her. A sequestrum was noted radiographically and was surgically debrided. After continued follow-up a left hind varus deformity was noted and was corrected with a lateral transphyseal screw in the distal left tibia. After the varus deformity was improved, a lateromedial radiograph was taken of the distal left tibia and tarsus and talocalcaneal subluxation was seen. The same view was taken of the right tarsus and the same deformity was noted. After finding no case reports on the condition with information on treatment or surgical correction, humane euthanasia was elected. A few months later, the same owner brought a two-month-old colt out of the same mare to the hospital for an elective procedure. Tarsal radiographs were taken due to the owner's previous experience, although the colt had no clinical history or any traumatic incidents. A lateromedial view of the right tarsus revealed talocalcaneal subluxation.
