Abstract: Fibrodysplasia ossificans progressiva (FOP) is a rare autosomal dominant disorder characterized by gradual replacement of muscle and connective tissue by bone due to heterotopic calcification. We report on a fourteen year old girl with clinical and radiological features of FOP. Patient had bilateral hallux valgus at the time of presentation. There was significant decrease in range of motion in the spine and shoulder joint. The radiographs showed heterotopic ossification in the thoracic region. The disease course was persistent with severe reduction in movement at joints and restriction of breathing movements.
