Popped Splints are associated with which etiologies?

• A. Overuse, trauma, nutrition-related hyperparathyroidism
• B. Overuse only
• C. Trauma only
• D. Nutritional deficiency only

Answer: (A)

Popped splints reflect irritation of the periosteum along the splint bones that is driven by multiple factors. Repeated stress from overuse creates microtrauma and inflammation of the periosteum, which is the most common trigger in young, actively training horses. Direct trauma can also provoke periosteal irritation and swelling along the splint bone. In addition, nutritional imbalances that lead to secondary hyperparathyroidism can weaken bone remodeling and predispose the splint region to inflammatory changes. Because each of these factors can contribute to splint formation, the combination of overuse, trauma, and nutrition-related hyperparathyroidism best explains popped splints.
