Splint Bone Injuries in the Horse
By Garrett Metcalf, DVM
Splint bone issues in horses are a common problem across various ages and disciplines. These injuries can be caused by excessive work in young horses or by traumatic injuries. The splint bones play an important role in the stability of the joints they help form at the knee or hock level. This article will discuss the different types of splint bone injuries and their treatments.
The splint bones are small bones that are intimately attached to the inside and outside of the cannon bone. To understand which section is injured, it’s helpful to break the splint bone down into three parts: the head, the mid-body section, and the button. The head of the splint bones forms part of the carpus (knee) in the forelimb and part of the hock in the hindlimb. Research has demonstrated the important role splint bones play in the stability of these joints. A study conducted at Colorado State College of Veterinary Medicine noted that when larger portions of the splint bone were removed, rotational stability in the carpus was significantly impacted, and other directional forces were also affected.
Diagnosing splint bone injuries is generally straightforward with radiographs, though in some cases, ultrasound can also be helpful. Bone or callus formation around these splint bone injuries can compress the suspensory ligament, leading to chronic pain and lameness issues.
Popped Splints
“Popped splints” refer to injuries that generally occur in younger horses entering training and work. These injuries typically affect the inside forelimb splints and can be quite painful, leading to loss of training time. A popped splint is the result of tearing the ligament that holds the splint bone to the cannon bone, known as the interosseous ligament. When the ligament is torn, bleeding can occur, disrupting the periosteum of the bones and causing a callus or firm bony lump.
The inside splint on the forelimb is more prone to injury because it bears direct load with the second carpal bone at the head of the splint bone. This places direct force on the splint bone, while other splint bones share the load with adjacent carpal or hock bones.
Popped splints are often painful, with noticeable swelling near the splint bone and heat present. When palpated, a moderate amount of pain will be elicited.
Treatment for popped splints typically includes rest, systemic anti-inflammatory drugs, and local anti-inflammatory treatments. Acute inflammation can be soothed with ice, cold therapies, and bandaging. Alternative therapies such as cold laser therapy, MagnaWave, or shockwave therapy can also be incorporated into the treatment plan. In more extreme cases, surgical removal of the bone callus may be necessary to prevent compression of the suspensory ligament.
Splint Bone Fractures
Splint bone fractures can occur at any level of the splint bone, but some areas are more commonly fractured. The distal one-third of the splint bone is most often fractured in the forelimbs. These fractures are occasionally associated with forelimb suspensory ligament issues. The suspensory ligament has a small attachment to the button of the splint bone, and when the lower limb is heavily extended, bending forces on the lower part of the splint bones can lead to fractures.
In the hind limb, the outside (lateral) splint bone is the most commonly fractured. These fractures often result from kicking injuries. When two horses don’t get along and kick at each other, the lateral splint bone is often the one that gets broken. These injuries are particularly problematic due to the open wounds that are heavily contaminated with manure, hair, and dirt, as well as injuries to flexor tendons.
Fractures near the head of the splint are especially problematic and can sometimes be career-ending or life-threatening. These fractures can involve the joints of the carpus or hock, leading to septic arthritis, severe lameness, and possibly serious instability of the corresponding joint. The rule of thumb for equine veterinarians when surgically removing damaged or fractured splint bones is the “two-thirds, one-third rule.” This means the lower two-thirds of the splint bone can be safely removed, but the upper one-third should be preserved whenever possible. Complete removal of the upper one-third of the splint bone can lead to chronic lameness or, worse, catastrophic joint dislocation when the horse attempts to rise from anesthesia. In some cases, the fractured upper one-third of the splint can be repaired using plates and screws to maintain stability in the joint.
Smaller traumatic injuries to the splint bone often occur from interference injuries or when the horse’s own feet hit the inner splint bones during work. These injuries can be prevented with the use of splint boots on the lower limbs during exercise. Some lower limb boots provide support to the fetlock and suspensory ligament, which can help prevent distal splint bone fractures, although they are not always fully protective.
Conclusion
Some splint bone injuries are relatively simple and common issues that many horse owners can address. However, more serious traumatic fractures and wounds related to splint injuries should be examined by a veterinarian. If you suspect a splint bone injury, it’s best to consult a professional to ensure proper treatment and prevent further complications.

Winter Water Solutions
Winter brings its own set of challenges. For ranchers and horse owners, few are more pressing than keeping water available. Cold weather, frozen tanks, and ice buildup can cut animals off from the single most important nutrient. Cattle can survive on short pasture and horses can get by on hay, but without water, everything stops. Hydration affects digestion, body temperature regulation, and overall health. That’s why every winter, producers across Oklahoma and North Texas turn their focus to one essential question: how do you keep water flowing when the mercury drops?
The struggle against frozen water isn’t new. Generations before electricity, rural families learned to outsmart the cold with ingenuity and grit.
Chopping Ice – One of the oldest solutions was also the most labor-intensive: grabbing an ax or a bar and breaking ice daily. While effective, this method demands constant attention and becomes impractical during long cold snaps. Horses and cattle can quickly fall behind on intake if a rancher misses even a few hours.
Windmills and Groundwater – Traditional windmills pumping from underground aquifers often provided water that was warmer than surface tanks, since groundwater stays at a relatively stable temperature year-round. Many old ranches still rely on this method, though windmill upkeep is a challenge in itself.
Insulated or Buried Lines – Families learned to bury water lines below the frost line or wrap them with insulating material. That practice continues today, and it remains one of the most effective long-term strategies for preventing frozen pipes.
Floating Devices – Ranchers also improvised with floating logs, balls, or even old tires in stock tanks. The movement helped keep ice from sealing solid and gave livestock a space to drink. While not foolproof, the idea is still used in remote areas.
These methods show the persistence of rural people, but modern technology has added new tools to the fight.
Today, ranchers and horse owners have a wide menu of winter water solutions, ranging from simple add-ons to major investments.
Heated Waterers – Electric or propane-powered waterers remain the most reliable way to ensure animals never face ice. Available in tank heaters, floating units, or fully enclosed automatic waterers, they keep temperatures above freezing even during prolonged cold. The trade-off is cost: electricity bills can spike, and in rural areas, running lines to distant tanks may not be practical. Still, for barns, lots, and heavily used pastures, heated waterers are a standard tool.
Solar Solutions – Where electricity isn’t available, solar-powered heaters have gained traction. Panels run small heating elements or pumps, reducing reliance on grid power. Though initial costs are high, they provide independence and sustainability, especially in sunny but cold climates.
Geothermal Systems – Some operations use earth’s steady underground temperature to keep water from freezing. By burying lines or tanks and tapping into geothermal exchange, water stays at safe levels without heavy energy use. These systems are especially effective when designed into new construction.
Automatic Waterers with Constant Flow – In some cases, ranchers use systems that keep water trickling constantly. Movement prevents ice buildup, though it can waste water if not carefully managed. This method works best where water supply is abundant and low-cost.
Tank Additives – While chemicals are never recommended for human or animal safety, some producers use nontoxic dyes or floating covers to limit algae and ice. These are niche options, but they illustrate the creativity at play.
Practical Ranch Hacks – Many ranchers mix and match. Submersible de-icers paired with insulated tank covers, old truck hoods repurposed as windbreaks, or even placing tanks on south-facing slopes to maximize sun exposure can make the difference between usable and frozen water.
Why does all this matter so much? Because winter dehydration can have cascading effects. Horses, for instance, are prone to impaction colic when water intake drops. Cattle that can’t drink freely eat less feed, lose weight, and struggle to maintain body condition. Calves and older animals are especially vulnerable. Even wildlife around a farm benefits from accessible water sources.
Beyond animal health, reliable winter water reduces labor stress. Instead of breaking ice in multiple tanks at dawn and dusk, producers with dependable systems can focus on feeding, calving prep, or other winter tasks. In a season where daylight is short and weather unpredictable, those saved hours are invaluable.
Water is the lifeblood of the ranch, and winter tests every producer’s ability to keep it flowing. From chopping ice with an ax to installing solar-powered heaters, solutions have evolved, but the goal is the same: hydration without interruption.
For some, a floating log and a good bar might still get the job done. For others, investment in heated automatic waterers pays off every year. The choice depends on herd size, geography, and budget. What unites them is the understanding that winter water is not optional. It is essential, and it always will be.

The Calf Roping Capitol
By Krista Lucas Wynn
Every fall, calf ropers descend onto a southwest Texas town for the annual Cinch Roping Fiesta, in San Angelo, Texas. The roping event was held October 23-26 and is the longest running stand alone roping event in the nation. The weekend features calf roping, breakaway roping, team roping, steer roping, and double mugging.
The fan favorite event is the invitational calf roping, featuring the top 30 of the Professional Rodeo Cowboys Association world standings, as well as five from a qualifying event held the day before. Bryce Derrer, of Portales, NM, dominated the competition by winning both go rounds and the average. He pocketed over $16,000 for his efforts.
Tom Crouse, Blane Cox, Chet Weitz, and Tyson Durfey followed Derrer in the first round, placing second through fifth respectively. Zane Kilgus, Cody McCartney, Logan Bird, Cash Enderli, and Riley Webb rounded out the second go round. Previously featured NTFR calf roper and local cowboy, Hagen Houck, also competed at the roping fiesta for the first time.
Weitz, of London, Texas, bested the short go field, with a time of 9.6 seconds. Kincade Henry, Webb and Brey Yore rounded out the final round.
World champion, Webb, also roped against world champion and 10 time Wrangler National Finals Qualifier, Caleb Smidt, in a 12 head match. Smidt retired in 2025 but still hung with Webb up until a missed calf cost him time. After that, Webb stayed consistent to finish the match with a time of 197.1 seconds, a full minute and a half ahead of Smidt.
A fan favorite event has quickly become the legends match, presented by O-H Triangle Ranch, during the calf roping event. This year, WNFR qualifiers, Jeff Chapman and Ricky Canton went head to head on six calves. Canton was the returning champion but was bested by Chapman after a back and forth contest. Chapman finished with a time of 84.3 seconds, and Canton turned in a total time of 91.7 seconds.
With three full days of roping, a remodeled arena, and beautiful weather, roping fans of all ages and disciplines had something to watch. Winnings for the calf roping and steer roping will count for the 2026 PRCA world standings. For full results, visit www.sanangelorodeo.com.

Crunch Time
By Krista Lucas Wynn
As rodeo fans look forward to the 2025 Wrangler National Finals Rodeo, some professional cowboys and cowgirls made their dreams a reality, while others were pushed out at the very last second. The 2025 professional rodeo season wrapped up September 30th, and it took more money than ever before, with payouts larger than ever before.
Within the last week of the 2025 season alone, there were multiple rodeos scattered across the country, but most eyes were set on the Governor’s Cup held in Sioux Falls, SD.
Held the last weekend of September, the Governor’s Cup had the biggest payout with each round paying over $11,000 to win it, with Sunday’s finals being a clean slate and $32,000 going to the winner. This meant the Governor’s Cup had huge implications on the top 15.
In the bareback riding, young gun Rocker Steiner added to his lead in the standings by advancing to the final round where he rode Cosmic Stardust for 88 points. Tilden Hooper came into the event in 17th place and was able to move up to 14th by placing sixth and third in both rounds, keeping the veteran’s WNFR dreams alive.
Steer wrestlers, Cody Devers and Gavin Soileau, both created opportunities to advance to the final round, but both would also end in heartbreak. Devers, who was 16th in the standings, split third in the first round, and then missed his second steer. Soileau advanced all the way to Sunday, where he missed his steer to advance to the final four round. He went on to catch a chartered plane to San Bernadino, CA where he would win enough to slip into the top 15, showing what all it takes to even have a chance at the WNFR. Justin Shaffer, of Hallsville, Texas, won the event moving up to third place for his second WNFR qualification.
Going into the Governor’s Cup, team ropers Luke Brown and Trey Yates found themselves fighting for a spot in the top 15. They came out with a bang by winning the first round for $11,911 each. World champions Kaleb Driggers and Junior Nogueira moved back into the number one spot in the standings after they won the second round, the semifinals and the final four round.
In the saddle bronc riding, Q Taylor and Ben Anderson took advantage of the big money by both advancing to the Sunday finals. They both moved into the top 15, forcing Wyatt Casper and Lefty Holman on the bubble.
The calf roping was no different than most of 2025, featuring a showdown between Riley Webb and Shad Mayfield. World champion, Shane Hanchey, did not go quietly though. He came into the event in 16th place, and after placing in both long rounds, fought his way into the top 15.
In the breakaway roping, Bailey Bates and Martha Angelone both needed to win money in order to move up into the top 15. Both ended up advancing to the final round, even with Angelone having a broken barrier. Angelone ended up breaking out again in the final four, and Bates roped a 2.1 to win the Governor’s Cup. She moved up to 12th in the standings, while Angelone unfortunately finished 16th for the year.
Texas cowgirls, Halyn Lide and Tricia Aldridge, both did what they needed to do in barrel racing. Aldridge rode her standout stallion, Adios Pantalones, to their first WNFR qualification. They placed seventh and fifth in the rounds, advancing to the semifinals. Then, ran the fastest time in the semifinals and finished second in the finals behind Halyn Lide. Lide placed eighth in both rounds, fourth in the semifinals and won the finals securing her spot at her second WNFR.
Meanwhile, Lide’s sister-in-law, Katelyn Scott, was battling it out at five rodeos across the country to qualify for her first WNFR. She won a total of $9,118 in the last week of the regular season, and slid into the 15th spot to join her sister-in-law at the WNFR.
World champion bull rider, Ky Hamilton, rode all four bulls at the Governor’s Cup to walk away with the win and qualify for his fifth WNFR. Clayton Sellers had a chance to capitalize on the money up for grabs but got bucked off in the final round. Sellers, along with other roughstock cowboys, had to await their fate up to the very last day of September, after the inaugural event, Duel at the Dunes, concluded.
