TRAUMA-MYOSITIS OSSIFICANS

SUMMARY

1. Occurs in up to 10% to 20% of all thigh contusions, and the quadriceps is the most common location.

2. Inx: radiographs, bone scan & MRI (more sensitive in the early stages) to look for clacification within tendons and muscles.

3. First-line treatment includes progressive range of motion and medication.

4. Radiation therapy can be tried for recalcitrant symptoms.

5. Surgical resection of the calcified tissue is indicated for unresponsive cases but should not be undertaken before maturation of the mass because of the high risk for recurrence.

6. A cold bone scan provides evidence that osteoblastic activity has ceased.
