Fibrodysplasia ossificans progressiva

void any invasive procedures that involve tissue injury. If a biopsy or imaging is necessary, use non‑invasive alternatives (e.g., ultrasound or MRI) whenever possible. For unavoidable procedures, use local anesthesia and gentle handling; avoid intramuscular injections and blunt trauma. Inform all healthcare providers of the FOP diagnosis so they can plan a trauma‑free approach and consider pre‑emptive anti‑inflammatory therapy (e.g., NSAIDs) after the procedure. How can caregivers help a child with FOP maintain adequate breathing and prevent respiratory complications?::Regular pulmonary function monitoring (spirometry) every 6–12 months helps detect early restrictive lung disease. Encourage gentle, assisted range‑of‑motion exercises that do not stress the chest wall. In advanced cases, a pulmonologist may recommend non‑invasive ventilation support at night. Avoid activities that compress the thoracic cage, such as heavy lifting or certain sports, and use a supportive chest binder only if prescribed by a specialist. Are there any treatments that can slow or stop the progression of heterotopic bone formation in FOP?::Currently, no therapy has proven to halt progression, but several investigational drugs are in clinical trials. The most studied is a selective activin A receptor type I (ACVR1) inhibitor, which targets the mutated pathway. Patients may also receive high‑dose corticosteroids during flare‑ups to reduce inflammation, though long‑term use is limited by side effects. Participation in a clinical trial can provide access to emerging therapies and close monitoring. What is the best approach to manage pain and inflammation during a flare‑up in FOP?::Immediate treatment with high‑dose oral or intravenous corticosteroids (e.g., methylprednisolone 1–2 mg/kg/day) can reduce swelling and pain. Non‑steroidal anti‑inflammatory drugs (NSAIDs) are often used as adjuncts but should be avoided if they increase the risk of bleeding. Physical therapy should be paused during active flare‑ups to prevent further trauma. Pain can also be managed with acetaminophen or, in severe cases, opioid analgesics under strict medical supervision. A multidisciplinary team—including rheumatology, pain management, and physical therapy—should coordinate care to balance symptom relief with the risk of triggering new ossification.
