Fractures in cattle most often happen from trauma or accidents, the cause of which varies by age and environment. The majority of fractures in calves are a result of dystocia or rough handling at birth, while older animals tend to suffer fractures from falls on slick surfaces, collisions or getting stuck on equipment. Nutritional and hoof health issues can also contribute to the likelihood of injury, making management a key part of prevention.
To achieve optimal outcomes for fracture healing, it is important to stabilize the limb, protect the soft tissue, and set the animal up for a good recovery. With the right approach, even a tough orthopedic case can become a manageable on-farm success story.
1. Keep the Soft Tissue Alive
Before thinking about fiberglass or bandage layers, take a good look at what’s happening under the skin. Fracture healing depends just as much on circulation and soft-tissue health as how straight you set the bone.
A few things to keep in mind:
- Swelling happens. In the first couple days, edema and inflammation can turn a snug cast into a tourniquet. Leave space for expansion or plan to bivalve the cast if needed.
- Pressure points are the enemy. Pad bony areas with orthopedic felt or thick cotton.
- Check perfusion. Ensure bandaging is tight enough to stay in place but loose enough to allow blood flow.
- Watch any wounds. If there’s an open abrasion, protect it with a non-stick dressing before you bandage. Never trap it in a cast unless you can guarantee airflow and drainage.
2. Splint first, ask questions later
The goal of splinting is simple: stop motion, protect tissues and make the animal safe to move. In injured calves, early immobilization drastically improves outcomes. Even a quick field fix can make the difference between a straightforward cast job and a long, messy recovery.
Dr. Pierre-Yves Mulon from the University of Tennessee College of Veterinary Medicine suggests the following for emergency stabilization splints in cattle:
- Splints need to be placed over a bandage. Never put a hard surface directly against skin.
- Splints need to touch the ground to off load the foot as the animal moves.
- Splints need to be placed orthogonally (except for tibial fractures).
- Splint length needs to be sufficient.
- Splints need to be adequately secured to the bandage.
3. Cast with Intention
Casting is the gold standard for distal simple fractures but only when soft tissue health is uncompromised and the animal’s environment is suitable.
Consider the following when casting:
- Technique basics. Include both joints above and below the fracture, and always include the hoof. Use fiberglass tape with polyurethane resin; it’s strong, lightweight and waterproof. Apply in a smooth spiral pattern, overlapping by half each turn.
- Padding matters. Start with a stockinette, then pad pressure points with orthopedic felt. Add cotton padding if swelling is expected.
- Layering. Expect to use eight layers for calves and 12 to 16 for adults.
- Reinforcement. If you’re working on a big or heavy animal, add an extra fiberglass layer or embed a metal bar for reinforcement.
- Growth. Remember that calves outgrow their casts fast. Check these animals every two to three weeks and replace any bandaging as needed.
- Removal. Use oscillating saws with caution making sure to cut medial and lateral sides until a change in resistance is felt. Spreaders or wedging tools assist with safe removal.
4. Fracture Type and Prognosis
All fractures are not made equal. Make sure your treatment and healing expectations match the situation.
- Calving-chain metacarpal fractures: Generally excellent prognosis with casting for six to eight weeks and bandage adjustments for growth.
- Growth-plate cannon fractures: Excellent outcomes have been observed with external cast therapy, as growth is typically unaffected by temporary cartilaginous disruption.
- Femoral fractures: Closed repairs seldom succeed; expensive surgical fixation is needed but has fair to good results when anatomy permits (i.e. breeding stock).
- Tibial and high diaphyseal fractures: Proximal joint motions often compromise healing unless reinforced or pinned.
Overall, great success rates can be achieved in fracture cases handled with splints or casts so long as the soft tissue is intact and immobilization is prompt.
5. Herd Care: Environmental and Management Strategies
Even the best splint or cast can fail without supportive management. Daily monitoring of comfort and function is critical. Calves should be confined to clean, dry pens, removed from the herd to prevent trauma and assessed daily for early signs of cast complications. Subtle reductions in weight-bearing could indicate splint/cast failure or secondary injury.
Reassessment after removal is equally vital. Many fractures seem resolved after cast removal, but incomplete healing or soft tissue scarring can lead to long-term lameness if undetected. Rechecking seven to 10 days after removal and again at four to six weeks posthealing is recommended.
Fracture management doesn’t have to mean complicated surgery or expensive equipment. With thoughtful splinting, careful casting and good follow-up, you can get excellent results in the field.
