Plain-English summary
A 5-year-old Arabian stallion had swelling in his right wrist and was occasionally limping. He was found to have a bone growth called an osteochondroma that was pushing into the area around his wrist. For three years, he managed to stay active with medication, but when the lameness returned, the owner chose to have the growth surgically removed. The surgery involved using a small camera to locate the growth and then taking it out through a small cut. After the surgery, the swelling and limping improved within two months, and the horse was able to return to training four months later.
Abstract
A 5-year-old Arabian stallion with moderate effusion in the right carpal canal and intermittent lameness in this limb was diagnosed to have an osteochondroma projecting from the distal portion of the radius into the carpal canal. oral phenylbutazone treatment over the next 3 years allowed the stallion to continue its show career. Right forelimb lameness returned at that time, and ultrasonography revealed the osteochondroma impinging on the dorsal surface of the deep digital flexor tendon. The owner elected to have the osteochondroma surgically removed. The horse was anesthetized, and the carpal sheath was distended with balanced polyionic solution. A 4-mm arthroscope was inserted into the carpal sheath, and the osteochondroma projecting into the sheath was identified. The osteochondroma was removed by use of a Ferris-Smith bone rongeur, which was inserted into the carpal sheath through a stab incision over the osteochondroma. The effusion in the carpal sheath and the lameness resolved by 2 months, and the horse was returned to training 4 months after surgery.
