Introduction
March fractures, also known as stress fractures or fatigue fractures, are common injuries that occur in the bones of the feet and lower legs. They are named after the month of March because they were first described in military recruits who experienced these fractures during intense training exercises in that month. March fractures typically result from repetitive stress or overuse, leading to small cracks or fractures in the bone.
What Are the Causes?
These fractures commonly occur when the bones are subjected to excessive and repetitive forces, exceeding their ability to adapt and repair themselves.
Several factors contribute to the development of march fractures:
-
Overuse and Repetitive Activities: Engaging in activities that involve repetitive impact or stress on the feet and lower legs, such as running, jumping, or dancing, can overload the bones over time. These repetitive motions create microtrauma, leading to small cracks or fractures in the bone.
-
A Sudden Increase in Activity: A sudden increase in the intensity, duration, or frequency of physical activities without allowing sufficient time for the body to adapt can strain the bones. This sudden change can overwhelm the bones' ability to repair themselves, making them more susceptible to fractures.
-
Insufficient Rest and Recovery: Inadequate rest between physical activities and insufficient recovery time can prevent the bones from healing properly. Without enough time for repair and remodeling, the bones become more vulnerable to stress fractures.
-
Poor Choice of Footwear: Wearing improper footwear or shoes that lack proper support, cushioning, or shock absorption can increase the stress on the bones. Inadequate footwear fails to absorb the impact forces adequately, transferring more stress to the bones and increasing the risk of fractures.
-
Biomechanical Factors: Certain biomechanical factors, such as abnormal foot arches, muscle imbalances, or gait abnormalities, can alter the distribution of forces on the bones. These imbalances can create excessive stress in specific areas, making them more prone to stress fractures.
-
Weakened Bones: Conditions that weaken the bones, such as osteoporosis or nutritional deficiencies (especially calcium and vitamin D), can increase the risk of developing stress fractures. Weaker bones have reduced resistance to the repetitive stresses encountered during physical activities.
It is important to note that individual susceptibility to March fractures can vary, and some people may be more prone to developing these fractures due to factors like age, gender, previous injury, and underlying medical conditions.
Which Bones Are Most Affected?
March fractures can affect various bones in the feet and lower legs. The most commonly affected bone is the second metatarsal, which is one of the long bones in the middle of the foot. The third metatarsal is also frequently involved. These metatarsal bones are susceptible to stress fractures due to their role in supporting body weight during activities like walking, running, and jumping.
Aside from the metatarsals, other bones that can be affected by march fractures include:
-
Tibia (shinbone).
-
Fibula.
-
Calcaneus (heel bone).
It is important to note that the specific bone affected can vary from person to person, depending on the type and intensity of activities performed, as well as individual factors like biomechanics and bone density.
What Are the Symptoms?
Here are some common symptoms associated with March fractures:
-
Pain: The primary symptom of a March fracture is pain, which is often described as a dull ache or throbbing sensation. The pain tends to worsen with activity and may subside with rest. Initially, the pain may be mild and only occur during physical activity, but it can progress and become constant over time.
-
Swelling: Swelling around the affected area is another common symptom. The injured foot or lower leg may appear swollen, and there may be localized tenderness when touching the affected bone.
-
Bruising: In some cases, bruising (discoloration) may be present, particularly if the fracture is severe. The bruising can range from mild to more pronounced, depending on the extent of the injury.
-
Difficulty Walking: As the fracture progresses, walking or bearing weight on the affected foot can become increasingly painful. This can lead to a limp or altered gait pattern.
-
Increased Pain With Pressure: Pressing on or applying pressure to the specific area of the fracture may elicit significant pain.
-
Gradual Onset: March fractures often develop gradually over time as a result of repetitive stress.
The symptoms may start as mild discomfort and progressively worsen with continued activity.
It is important to note that these symptoms are not exclusive to March fractures, and other conditions such as sprains, tendonitis, or other fractures can produce similar symptoms.
What Is the Treatment?
The treatment for March fractures typically involves a combination of rest, pain management, and a gradual return to activity. Here are some common approaches:
-
Rest: Resting the affected foot or leg is crucial for allowing the fracture to heal. This may involve avoiding activities that put stress on the injured area, such as walking or running. In severe cases, crutches or a walking boot may be recommended to minimize weight-bearing.
-
Immobilization: Depending on the severity of the fracture, immobilization may be necessary to promote healing. This can involve wearing a cast, walking boot, or using a splint to restrict movement and provide support to the injured bone.
-
Pain Management: Over-the-counter pain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) like Ibuprofen, can help relieve pain and reduce inflammation. However, it is essential to consult a healthcare professional before taking any medication to ensure it is suitable for the specific situation.
-
Ice Therapy: Applying ice to the affected area can help reduce pain and swelling. Use an ice pack or wrap ice in a thin cloth and apply it to the injured area for 15-20 minutes at a time, several times a day.
-
Compression: Using compression bandages or wraps can help reduce swelling and provide support to the affected area. Be cautious not to wrap too tightly, as it can impede circulation.
-
Elevation: Elevating the injured foot or leg above the level of the heart can help reduce swelling. Prop the foot up on a pillow or cushion when sitting or lying down.
-
Physical Therapy: Once the initial healing stage is complete, a healthcare professional may recommend physical therapy to strengthen the muscles surrounding the affected area and restore flexibility and function. They can guide one through appropriate exercises and a gradual return to weight-bearing activities.
Conclusion
March fractures affect the bones of the legs and feet. It is important to follow the advice and treatment plan provided by the healthcare professional, or orthopedic surgeon as the exact approach may vary depending on the severity of the fracture. They will be able to provide personalized recommendations based on the specific condition. One should adhere to the instructions given by the healthcare provider for a speedy recovery.
