What best characterizes a skeletal muscle contusion?

A skeletal muscle contusion is best understood as injury from a direct blow that causes bleeding into the muscle. When the muscle is struck, small blood vessels rupture and blood accumulates within the muscle tissue, creating a hematoma along with swelling and tenderness. This intramuscular bleeding is the defining feature and explains the visible bruising and functional limitation that follow. Myositis ossificans can occur later if a hematoma is large or poorly managed, but that is a potential complication rather than the characteristic feature of a contusion. Saying bleeding within the muscle is uncommon is incorrect, since intramuscular hemorrhage is the typical event after a contusion.
