Smoke, a talented barrel racing Quarterhorse, faced an unexpected challenge when he started showing unusual neurologic symptoms. Referred to the specialists at UF Large Animal Hospital for further evaluation, Smoke had already undergone a CT scan that revealed an enlarged temporohyoid joint (THO)—a condition that typically causes specific neurologic signs. However, Smoke wasn’t exhibiting the classic symptoms of THO, such as head tilt, muzzle deviation, inability to blink, or ataxia. Despite this, the neurologic exam didn’t reveal any other obvious causes for his symptoms, which included hyperesthesia, irregular behavior, and resistance when turning right around barrels.
With no clear explanation for his issues, Smoke’s owner, trusting in the expertise of the UF team, opted to proceed with surgery on the temporohyoid joint in hopes of improving his condition. Dr. Heather Roe, Clinical Assistant Professor of Large Animal Surgery at UF, made the decision to perform the surgery while Smoke was standing—a novel approach for this procedure.
The procedure aimed to reduce the pressure on the affected joint, with hopes to help alleviate Smoke’s neurologic symptoms.
“We had extensive discussions with the owner about the surgery,” said Dr. Roe. “While we knew that Smoke’s symptoms didn’t fit the typical profile for THO, we didn’t have an alternative explanation. We decided to proceed with the surgery, hoping it could help resolve his issues. Surgery on the temporohyoid joint can be challenging given the complex anatomy and large local vessels. Performing it while the horse is standing can reduce the risks associated with general anesthesia, particularly in neurologic horses.”
Smoke’s surgery was a success, and he had an uncomplicated recovery. Within just a few weeks, the abnormal symptoms he had been experiencing began to resolve. Smoke returned to the arena stronger than ever, and his owner reported that he was performing at an even higher level than before.
“We are thrilled with the outcome,” Dr. Roe said. “It’s always rewarding to see a horse return to the sport they love, especially when the owner trusted us to make such an important decision. Smoke is a truly special horse, and we’re so pleased we could help him get back to living his dream.”
Today, Smoke is back to barrel racing, and his owner couldn’t be happier with his renewed performance. This case is a perfect example of how innovative techniques, combined with expert care and trust between owner and veterinarian, can help a horse overcome even the most perplexing challenges and return to doing what they do best.
