What type of injuries can enter joints and tendons?

Wounds are indeed the type of injuries that can enter joints and tendons. When a wound occurs, especially if it's a penetrating wound or a deep laceration, it can expose underlying structures, including joints and tendons, to the external environment. This creates a risk of infection, inflammation, and damage to the affected structures. Proper care of wounds is crucial in preventing further complications that could affect the joints and tendons.

In contrast, fractures primarily involve the breaking of bones and do not directly pertain to injuries that enter joints or tendons. Infections can stem from wounds but are not themselves a physical injury type. Bruises, while they indicate soft tissue trauma, do not typically penetrate into joints or tendons. Understanding these distinctions helps in effectively diagnosing and treating equine injuries.
