Senior Senator's Triumphant Return

Senior Senator has been called “one of the craziest horses that ever looked through a bridle.”  

But a serious accident in May 2017 temporarily dampened some of the eight-year-old gelding’s fiery, unique personality, nearly ending his racing career. While defending his 2016 Maryland Hunt Cup title at the 2017 race, the Thoroughbred and jockey Eric Poretz tumbled at the third fence in the notoriously challenging four-mile timber course.

“After the fall, Senior Senator jumped up and galloped to the receiving barn,” said Vicki Crawford, who owns the horse with her husband Irvin “Skip” Crawford. “Because he was so quick to run off, we didn’t think too much of the fall. It really wasn’t until we saw close-up photos of the accident that we realized how serious it was.”

Veterinarian Dr. Cooper Williams, VMD, the horse’s regular doctor and onsite medical staff at the annual race, was concerned right after the tumble. “It’s not unusual with rotational falls involving the head and neck for a horse to appear relatively normal clinically,” said Williams, V’85. “Because of this, we strongly recommend x-rays of the neck after a major fall. Early diagnosis can prevent disasters.”

In Senior Senator’s case, the Crawfords and trainer Joe Davies readily agreed. Due diligence paid off when Williams diagnosed a serious fracture of the neck, involving the fourth and fifth cervical vertebrae. He immediately emailed the images to Dr. Dean Richardson, Charles W. Raker Professor of Equine Surgery, at Penn Vet’s New Bolton Center, and called Richardson to discuss a possible surgical repair.

“Worldwide, Dean is one of the top orthopedic specialists for equines,” said Williams. “And he’s an expert at working in complicated anatomical regions of the horse.”

Robotic Input

In Kennett Square, Richardson reviewed Williams’ referral x-rays that showed a fracture of the fourth cervical vertebra. “This was a horrible crash, really horrific,” recalled Richardson. “But I saw a more than reasonable chance of successfully repairing the injury with surgery.”

Senior Senator traveled to New Bolton Center, where Richardson used the School’s robotics-controlled computed tomography (CT) system to obtain the precise details of the break. Penn Vet is the first veterinary teaching hospital in the world to use the revolutionary equipment that enables clinicians to exam an awake, moving, and weight bearing horse.

“Providing 3D images, this technology offers us tremendous advantages over traditional x-ray and other imaging options,” said Richardson. “And we can evaluate our patient and plan for surgery without having to put the horse under anesthesia, which is a big deal.”

Forearm Length Procedure

Once anesthetized, Senior Senator was placed on his back. Richardson and his team used a large fluoroscope — a movie like x-ray machine that shows images in real time — to mark and make incisions on the horse’s neck and sternum. 

After opening the targeted area, they then cleared a path to the spine. “We used retractors to move the important and very vulnerable internal parts of the body —like the trachea, carotid artery, jugular vein, and esophagus out of the way,” Richardson explained.

With careful precision, Richardson reached into Senior Senator’s neck at least the length of a forearm to repair the break. The team first removed a large amount of painful disc material between the end plates of the fractured bone and used screws to stabilize the fourth and fifth vertebrae. They then packed the space between the vertebrae with bone grafted from the horse’s sternum, locking everything into place with a stainless-steel compression plate and carefully closing the incision. 

“Spa” Time

Recovery for an anesthetized animal weighing over 1200 pounds is tricky to manage. Penn Vet’s landmark recovery pool, part of New Bolton Center’s surgical suite in the C. Mahlon Kline Orthopedic & Rehabilitation Center, makes the transition from unconsciousness to consciousness much safer.

Asleep and in the sling, Senior Senator was moved from the operating room to the recovery pool and lowered into a very large rubber raft with four extensions that contain the horse’s legs. The anesthesia wore off while he was floating in the pool.

“We keep the temperature of the pool very close to the horse's body temperature. Otherwise, the animal will get chilled and not wake properly,” Richardson said. “Basically, to the horse it feels kind of like a spa.”

Typically, a horse remains in the recovery pool for an hour or two. When it wakes, the water gets to work. “Horses are prey animals, so they want to run away as fast as possible when they feel fear,” Richardson continued. “But post-surgery, if they don’t have full neuromuscular control they’ll flail, increasing the chances of falling and re-fracturing the neck. The water provides resistance, keeping horses from flailing. In the pool, they quickly realize there’s not much they can do and usually just chill out.”

Senior Senator adapted well to the pool. Once he was fully alert, the team used the sling to move him to the recovery stall, where they carefully lowered him 15 feet to the floor and removed the sling.     

“He was immediately comfortable after the surgery,” Richardson noted. “And his aftercare recovery could not have gone better. He was a perfect patient. He acted like he knew we were helping him and didn’t fight us at all.”

Champion Once and Again

“This surgery saved Senior Senator’s life,” said Crawford of the May 2017 procedure. Richardson credits the full surgical team for its success, including New Bolton Center’s anesthesiology nurses, Dr. Kyla Ortved, Assistant Professor of Large Animal Surgery, and Dr. Thomas Schaer, Director of the Comparative Orthopedic Research Laboratory.

Over the course of 12 months, Senior Senator’s recovery progressed at Davies’ farm under the watchful eyes of his extended care team — Richardson, Williams, Davies, and the Crawfords. All were hopeful that this special horse would race again. At the same time, they were prepared to accept he’d had a great flash of glory and might retire a one-time Maryland Hunt Cup winner, the youngest in 50 years.

Like always, Senior Senator had his own plan — he wasn’t ready to bow out quite yet. A year after his terrible accident, in a brilliant comeback, the champ took home the 2018 Maryland Hunt Cup.

The school is a proud member of the One Health initiative, linking human, animal, and environmental health.

Penn Vet serves a diverse population of animals at its two campuses, which include extensive diagnostic and research laboratories. Ryan Hospital in Philadelphia provides care for dogs, cats, and other domestic/companion animals, handling more than 34,600 patient visits a year. New Bolton Center, Penn Vet’s large-animal hospital on nearly 700 acres in rural Kennett Square, PA, cares for horses and livestock/farm animals. The hospital handles more than 6,200 patient visits a year, while our Field Services have gone out on more than 5,500 farm service calls, treating some 18,700 patients at local farms. In addition, New Bolton Center’s campus includes a swine center, working dairy, and poultry unit that provide valuable research for the agriculture industry.
