A hairline fracture, or stress fracture, is a small crack or severe bruise within a bone that is common among athletes that are involved in running and jumping. People with osteoporosis are also more prone to developing hairline fractures. These injuries typically result from overuse or repetitive stress, often worsened by inadequate healing time between activities. The bones in the foot are particularly susceptible to stress fractures due to their role in absorbing impact during physical activities. Within the foot, the second and third metatarsals are frequently affected, as well as the heel, ankle bones, and navicular bone. Symptoms primarily include pain that worsens with activity and subsides with rest, swelling, tenderness, and bruising. Factors that can increase the risk of developing a stress fracture include participation in high-impact sports, certain foot structures, and weakened bones due to conditions like osteoporosis. Previous fractures, nutritional deficiencies, and improper equipment or techniques are other risk factors. Diagnosing a stress fracture often involves a physical exam and may require imaging tests like MRIs or bone scans, as X-rays might not detect fractures. If ignored, a stress fracture can worsen into a complete break. If you are experiencing foot pain during exercise, it is suggested that you schedule an appointment with a podiatrist for an exam, diagnosis, and treatment options.

Stress fractures occur when there is a tiny crack within a bone. To learn more, contact one of our podiatrists from North Bay Ankle & Foot Center. Our doctors can provide the care you need to keep you pain free and on your feet.

How Are They Caused?

Stress fractures are the result of repetitive force being placed on the bone. Since the lower leg and feet often carry most of the body’s weight, stress fractures are likely to occur in these areas. If you rush into a new exercise, you are more likely to develop a stress fracture since you are starting too much, too soon.  Pain resulting from stress fractures may go unnoticed at first, however it may start to worsen over time.

Risk Factors

• Gender – They are more commonly found in women compared to men.
• Foot Problems – People with unusual arches in their feet are more likely to develop stress fractures.
• Certain Sports – Dancers, gymnasts, tennis players, runners, and basketball players are more likely to develop stress fractures.
• Lack of Nutrients – A lack of vitamin D and calcium may weaken the bones and make you more prone to stress fractures
• Weak Bones – Osteoporosis can weaken the bones therefore resulting in stress fractures

Stress fractures do not always heal properly, so it is important that you seek help from a podiatrist if you suspect you may have one. Ignoring your stress fracture may cause it to worsen, and you may develop chronic pain as well as additional fractures.
