What condition involves the accumulation of calcium deposits in muscle tissue due to repeated trauma?

Myositis ossificans is characterized by the abnormal formation of bone tissue within muscle or soft tissue following an injury. This condition typically results from acute trauma or repeated blunt trauma to a muscle, where calcification occurs as part of the healing process, leading to the development of bone-like tissue in the affected muscle. This abnormal response can cause pain, swelling, and restricted muscle movement, ultimately impacting functional ability.

The other options describe different conditions that do not involve the formation of calcium deposits due to trauma. Muscle cramps are sudden involuntary contractions of one or more muscles, while hematomas refer to a localized collection of blood outside blood vessels typically due to trauma. Ligament sprains involve overstretching or tearing of ligaments but do not lead to the calcification seen in myositis ossificans. Thus, myositis ossificans is accurately identified as the condition involving calcium accumulation in muscle tissue as a result of repeated trauma.
