What Causes Metatarsal Stress Fractures?
Published: Jun 27, 2024
Metatarsal stress fractures are tiny cracks in the foot bones that happen from overuse. They are common in athletes and military recruits.
Why the Second Metatarsal?
The second metatarsal is more prone to stress fractures due to its unique placement and structure. It's longer and less mobile than other metatarsals, forcing it to bear more weight and stress. Biomechanical issues like Morton’s toe, where the second toe is longer, increase the risk of these fractures.
Common Risk Factors
Several factors increase the risk of stress fractures, including flat feet and tight calf muscles. Being overweight or having low bone density can also elevate the risk. External factors like wearing poor footwear and suddenly increasing physical activity are significant contributors.
Activities That Heighten Risk
Certain activities are more likely to cause these fractures, such as military training, running, and dancing. Switching to minimalist shoes without proper adjustment can also be risky. Ensuring gradual increases in activity can help mitigate these risks.
