While a standard fracture is usually the result of a single traumatic event, a stress fracture is a tiny crack in the bone caused by repetitive force or overuse. Both commonly affect the metatarsals, the navicular, and the calcaneus (heel bone).
The primary difference between the two is the speed at which pain develops.
Sudden, sharp pain at the time of injury for a standard fracture.
Pain that develops gradually and worsens during weight-bearing for a stress fracture.
Swelling on the top of the foot or the outside of the ankle.
Tenderness to the touch directly over a specific point on the bone.
Bruising that appears immediately with a traumatic break but may be absent with stress injuries.
Pain that subsides during rest but returns immediately upon resuming activity.
Imaging is essential because stress fractures are often invisible on initial X-rays.
Physical Examination
X-rays: Effective for identifying displaced or traumatic fractures but often fail to show stress fractures until they begin to heal.
MRI: The most sensitive tool for detecting bone stress and early-stage stress fractures before a visible crack appears.
CT Scan: Used for complex fractures involving joints to see the bone fragments in three dimensions.
The goal of treatment is to protect the bone while it remodels and regains its strength.
Depending on the location and severity of the fracture, non-weight bearing status using crutches or a knee scooter may be needed in some cases. In other cases, weight bearing with a walking boot for 6 to 8 weeks may be adequate.
Activity modification to eliminate high-impact movements like running or jumping.
Nutritional assessment to ensure adequate intake of calcium and Vitamin D for bone health.
Surgical intervention using plates, pins, or screws for displaced fractures or "high-risk" stress fractures like the fifth metatarsal or navicular.
