Stress fractures rank among the most frequent sports-related injuries. They entail small fractures in bones, typically resulting from repetitive strain induced by activities such as running. Despite being notably uncomfortable, they typically undergo self-repair with a few months of rest.
What Are the Symptoms of a Stress Fracture?
Stress fractures typically induce a persistent, achy discomfort around the fracture site, often exacerbated during exercise, walking, or standing. Another common symptom includes swelling in the affected area.
What Causes Stress Fractures?
Numerous sports activities heighten the likelihood of stress fractures. Engagements involving running and jumping pose a risk of fractures in the lower extremities or feet. Surpassing half of all stress fractures among adults and adolescents arise in the lower leg bones, with fractures of the tibia, the elongated bone in the lower leg, accounting for approximately 24% of all stress fractures.
While other sports involving repetitive motions, such as pitching or rowing, can lead to stress fractures of the humerus (the arm bone), occurrences of these are significantly less frequent.
What Puts You at Risk for Stress Fractures?
Stress fractures are markedly more prone to develop in individuals who have recently initiated a new exercise regimen or abruptly intensified their workout intensity. When muscles lack conditioning, they fatigue swiftly and cannot adequately support and cushion the bones. Consequently, greater pressure is exerted directly on the bones, increasing the risk of fracture.
Notably, stress fractures appear to be more prevalent in women. Additional risk factors for stress fractures include:
- Consuming more than 10 alcoholic beverages per week
- Smoking
- Running distances exceeding 25 miles per week
- Osteoporosis
- Eating disorders
- Insufficient levels of vitamin D
Anatomical irregularities, such as fallen arches, can unevenly distribute stress across the feet and legs, elevating the risk of stress fractures. Similarly, subpar equipment like worn-out running shoes can also contribute to this risk.
How Are Stress Fractures Diagnosed?
To diagnose a stress fracture, your physician will conduct a physical examination. Despite their utility, X-rays often fail to detect stress fractures. Consequently, your doctor may resort to MRI scans, nuclear bone scans, or other imaging techniques to make an accurate diagnosis.
What Is the Treatment for Stress Fractures?
Immediate care for stress fractures:
It is imperative to seek medical attention as untreated stress fractures may progress to complete bone fractures. Meanwhile, adhere to the RICE protocol:
- Rest: Refrain from weight-bearing activities and consider wearing a supportive, stiff-soled shoe if necessary.
- Ice: Apply ice to the affected area for 20 minutes at a time, wrapped in a towel, to reduce swelling for 24 to 48 hours. Avoid direct contact between ice and skin.
- Compression: Wrap the area with a soft bandage to alleviate swelling.
- Elevation: Elevate your foot or leg using pillows to a level above your heart.
Pain management medications:
Over-the-counter pain relievers can be used to alleviate discomfort. Doctors recommend acetaminophen over nonsteroidal anti-inflammatory drugs (NSAIDs) as NSAIDs may hinder bone healing.
Non-surgical interventions for stress fractures:
Surgery is typically unnecessary for most stress fractures. In addition to adhering to the RICE regimen to manage pain, your doctor may recommend one or more of the following treatments during the healing process:
- Crutches or a cane for support
- Protective footwear like boots or braces to reduce stress on the fracture
- Casts to immobilize the fracture during healing
You’ll be advised to refrain from high-impact activities like running for 6 to 8 weeks. Consider lower-impact exercises such as swimming or cycling instead.
Surgical options for stress fractures:
For severe stress fractures that do not heal independently, surgery may be necessary. Typically, the surgeon will utilize fasteners such as pins, screws, plates, or a combination thereof to stabilize the small bones of the foot and ankle.

Stress Fracture Recovery
A stress fracture typically requires 6 to 8 weeks to heal. Once the pain subsides, the doctor may conduct X-rays to confirm healing.
As swelling diminishes to the point where skin creases become visible, you can gradually apply light pressure to the area. Crutches or a cane may still be necessary. Generally, it is safe to resume full weight-bearing about 2 weeks after symptom onset. Weight-bearing activity can promote stress fracture healing, but avoid anything that causes discomfort.
For the subsequent 6 to 8 weeks, or until pain-free, refrain from the activity that led to the stress fracture and minimize weight-bearing on the affected area. Premature return to exercise can impede healing and potentially cause irreversible damage.
Initially, the doctor might recommend alternating active days. For instance, if you’re a runner, this means resting the day before and after a jog.
Keep in mind that rushing back into activity increases the risk of reinjury. Stress fractures have a tendency to recur, with approximately 60% of individuals who experience one having had a prior occurrence.
How Can You Prevent Stress Fractures?
Stress fractures often occur in individuals who rapidly escalate their physical activity levels. To prevent them, it’s essential to proceed gradually. Experts advise against increasing exercise intensity by more than 10% per week. Prioritize warming up and stretching for a few minutes before engaging in physical activity. Take regular breaks to allow your body to recover. If you experience pain during exercise, cease immediately; pushing through discomfort can exacerbate the risk of stress fractures.
Participating in high-impact sports and work activities heightens the likelihood of stress fractures.
Additionally, quality exercise equipment plays a crucial role in preventing stress fractures. Avoid wearing worn-out running shoes. Individuals with fallen arches or other anatomical issues may find custom inserts or arch supports beneficial for their shoes.
Conclusion
Understanding the dynamics of stress fractures and implementing preventive measures are paramount for individuals engaged in physical activities. Gradual progression in exercise intensity, adhering to the 10% rule, and incorporating warm-up sessions and stretches can significantly reduce the risk of stress fractures. Recognizing the importance of rest and listening to one’s body by halting activities at the onset of pain are crucial practices.
Moreover, investing in proper exercise equipment, including well-fitted shoes and appropriate support for anatomical issues, further fortifies preventive efforts. By fostering awareness and implementing these strategies, individuals can safeguard themselves against the debilitating effects of stress fractures, enabling them to pursue their physical endeavors with confidence and resilience.
