Fatigue fractures, also known as stress fractures, are tiny cracks in a bone that develop over time due to repetitive force or overuse. They are common in athletes and individuals who suddenly increase the intensity or duration of their physical activities. The most frequently affected bones are those in the legs and feet, such as the tibia, fibula, metatarsals, and calcaneus.

The primary cause of fatigue fractures is the bone's inability to withstand the cumulative stress placed upon it. This can occur when the rate of bone breakdown exceeds the rate of bone repair. Factors contributing to their development include inadequate rest between training sessions, improper footwear, insufficient calcium and vitamin D intake, and certain biomechanical issues like flat feet or high arches.

Symptoms typically include pain that worsens with activity and improves with rest. Swelling, tenderness, and localized pain at a specific point on the bone are also common. In some cases, pain may be present even during normal daily activities. Diagnosis usually involves a physical examination and imaging tests such as X-rays, although early stress fractures may not be visible on X-ray. Bone scans or MRI may be necessary for a definitive diagnosis.

Treatment for fatigue fractures primarily involves rest and reducing the stress on the affected bone. This often means discontinuing the activity that caused the injury for a period of weeks to months. Pain management may involve over-the-counter pain relievers. In some instances, crutches or a walking boot may be used to offload the bone. Once the pain subsides, a gradual return to activity is recommended, often with modifications to prevent recurrence.
