The main idea here is bone forming where it shouldn’t—in soft tissue after trauma. Myositis ossificans occurs when a hematoma within a muscle organizes and new bone tissue begins to form inside the muscle. Over time, osteoid is laid down and mineralizes, creating small pieces of bone within the soft tissue. This is different from conditions like osteoarthritis (degenerative changes at joints), bursitis (inflammation of a bursa), or tendonitis (inflammation of a tendon), none of which involve new bone forming inside muscle tissue. Clinically, you may see a localized, sometimes painful, firm mass that can limit movement, and imaging often shows a zonal pattern of mature bone at the periphery with less-formed tissue centrally as it matures. Management is typically conservative, with rest and gradual rehabilitation, though persistent or functionally limiting ossification may require further evaluation.
