Which condition is a serious complication after skeletal muscle contusion?

Myositis ossificans is the infection—wait, not infection—that bone forming within muscle after a blunt muscle contusion. This happens when the initial bleeding and inflammation in the injured muscle trigger cells to differentiate into bone-forming cells, leading to heterotopic ossification. As this bone develops, it creates a firm mass, limits range of motion, and can cause persistent pain and functional loss. It’s considered a serious complication because it changes normal muscle tissue into bone and can require long-term management, sometimes even surgical removal after maturation if it severely restricts movement. Tendinopathy, by contrast, is a tendon disorder usually from overuse or degeneration, not a direct result of a single contusion. Muscle fatigue refers to temporary decline in performance from energy depletion. Nerve entrapment is a nerve compression issue and isn’t the classic direct complication of a muscle contusion.
