Stress fractures are often referred to as hairline fractures, are associated with sports or dancing or overuse and repetitive activities. Most common locations are the calcaneus, metatarsals and navicular bone of the foot. Also other affected areas are the lower parts of the tibia and fibula bones of the leg.Returning to activity prematurely delays the healing process but also increases the risk for a complete/unstable fracture. Symptoms usually are pain and limitation in range of motion. Diagnosis is made via history taking, examination and x-rays/CT/MRI. Treatment usually includes reducing activities, non-weight bearing, joint splint.
