Heterotopic ossification in muscle after trauma or neurological injury. Common sites: quadriceps, brachialis, adductors. Symptoms: painful swelling → hard mass, ↓ROM. Radiology: peripheral calcification with central lucency (zoning). Treatment: rest, NSAIDs, physio; excision after maturation (>6–12 mo).
