General Information About Myositis Ossificans
Disease Details and Frequently Asked Questions
It is the formation of bone-like tissue inside the body where bone should not normally exist (especially within large muscle groups) as a result of calcium deposition.
It occurs when the healing process goes awry after a severe blow, intramuscular hemorrhage, or surgical trauma—typically in athletes (especially in the thigh and bicep muscles)—producing bone cells instead of muscle cells.
The appearance of a visibly palpable, hard, and painful mass (lump) in the impacted muscle 2-4 weeks after the trauma, along with a significant limitation in the range of motion of the joint in that area.
During the initial days, heat must never be applied, nor should firm massage be performed on the area with severe intramuscular hemorrhage (trauma). Such applications accelerate the ossification reaction.
Ossification (calcification) inside the muscle becomes visible on X-ray films obtained 3-4 weeks after the incident. In the early stage, MRI or Ultrasound is crucial to differentiate it from bone tumors.
During the first 6 months, only rest, ice, and analgesics (NSAID group, as these also suppress bone formation) are prescribed. In most cases, the body spontaneously resorbs this bone-like tissue over several months. If the muscle becomes completely locked, it is surgically excised after waiting 6 months to 1 year.
