Ossifying myositis is a condition in which bone is produced ectopically in muscle or other soft tissues and can be classified as progressive ossifying myositis, which is mostly associated with genetic factors. There is a type of traumatic ossifying myositis, in which the patient may have formed ectopic ossification in the muscle or muscle layer after multiple traumatic injuries. The current treatment suggests that if the patient develops symptoms, he should be treated as early as possible, either with medication or surgery. Surgical treatment is a more thorough method to remove the lesion. Physical therapy can be treated with acetate ion therapy or oral medications such as magnesium, bicarbonate phosphate, non-steroidal anti-inflammatory drugs, steroids and other internal medications, all of which have a role to play, but large-scale clinical trial studies are lacking.
