Plain-English summary

A Quarter horse filly was brought in with a two-week-old wound on her right hind leg after her mother stepped on her. X-rays showed a piece of dead bone (sequestrum) that needed to be surgically removed. Unfortunately, after surgery, the filly developed a leg deformity that required further surgery, but later tests revealed a serious joint issue (talocalcaneal subluxation) in both hind legs. Since there was no known treatment for this condition, the owner chose to humanely euthanize her. Later, the same owner brought in a colt from the same mare for a routine check-up, and X-rays showed he also had the same joint issue, even though he had no prior injuries.

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.
