Noun: 1. A rudimentary bone in the leg of an equine: A "splint bone" is one of two small, slender bones (the second and fourth metacarpals or metatarsals) found on either side of the larger cannon bone in the leg of a horse or a related animal. These bones are considered vestigial remnants of digits.
The term "splint bone" is a specific anatomical term used primarily in veterinary medicine, zoology, and equestrian contexts. It refers exclusively to these particular bones in the limbs of certain animals.
- Noun:
- The veterinarian took an X-ray to check for a fracture in the horse's splint bone.
- Inflammation of the connective tissue between the cannon bone and the splint bone is a common injury in racehorses.
- In equine anatomy, the splint bones run along the back of the cannon bone.
- "to pop a splint": An informal equestrian term describing the condition where a horse develops a bony enlargement (exostosis) on a splint bone, often due to injury or stress. It is called "popping" because the swelling can appear suddenly.

- Splint (noun): In a general medical context, a rigid device used to immobilize and protect an injured body part (e.g., a broken finger). This is a completely different meaning from "splint bone."
