Diagnosis and Treatment of Metatarsal Fractures in Wake County
What is a Metatarsal Fracture?
The structure of the foot is complex, consisting of bones, muscles, tendons, and other soft tissues. There are five metatarsal bones in each foot. These are long, slim bones that run the length of the foot to the base of the toes. A metatarsal fracture occurs when one of the long bones of the midfoot is cracked or broken. This may be due to sudden injury (an acute fracture) or repeated stress (a stress fracture).
The fifth metatarsal is the long bone on the outside of the foot that connects to the little toe. The fifth metatarsal bone is the most common to be fractured due to a sudden (acute) injury to the foot. It may break at various points along its length, depending on the type of injury. The first, second, and fifth metatarsals are the ones most frequently injured in sports.
Types of Metatarsal Fractures
Acute fractures are caused by a direct blow or impact, while stress fractures occur over a long period of time. An acute metatarsal fracture can be open or closed, and displaced or not displaced.
Open or closed
An open fracture is when the skin is broken over the fracture so that there is a route of possible infection from the outside into the broken bones. Open fractures cause more damage to the soft tissues around them, making treatment and healing more complicated.
Displaced or not displaced
A displaced fracture is one where, following the break, the bones slip out of line. In order to treat a displaced fracture, the bones need to be lined up and stabilized using some kind of metal pinning or plating.
Common Causes of Metatarsal Fractures
The main causes of a metatarsal fracture include:
- Direct blow to the foot: when someone steps on or kicks the foot, by dropping something onto the foot, or by falling onto the foot.
- Ankle twisting: when your ankle twists, it pulls on the ligament that attaches to the base of your fifth metatarsal.
- Overuse: activities like running and jumping can put repetitive stress on your metatarsal bones and can cause them to crack over time.
Symptoms of a Metatarsal Fracture
Acute metatarsal fractures and stress fractures often come with different symptoms. Your doctor will take the time needed to determine what type of fracture you have so that the most appropriate treatment method can be pursued. If you experience any of the following symptoms, please schedule an appointment with one of our orthopedic specialists today.
Acute Metatarsal Fractures
- You may hear a sound at the time of the break.
- Pinpoint pain (pain at the place of impact) at the time the fracture occurs and perhaps for a few hours later, but often the pain goes away after several hours.
- Bruising and swelling the next day.
- Limited mobility in the foot
Stress Fractures
- Pain with or after normal activity
- Pain that goes away when resting and then returns when standing or during activity
- Pinpoint pain when touched
- Swelling, but no bruising
How are Metatarsal Fractures Diagnosed?
To diagnose a metatarsal fracture, your Raleigh Orthopaedic physician will ask how the injury occurred and when the pain started. They will then examine your foot, gently pressing on different areas to determine where pain occurs. Imaging tests, such as an X-ray, will be ordered to visualize initial cracks and any irregularities in the bone as it starts to heal and remodel itself. In some cases, a bone scan or MRI may be performed to find stress fractures, since they do not show up easily on X-ray.
Treatment Options for Metatarsal Fractures at Raleigh Orthopaedic
Treatment will depend on which metatarsal bone is fractured, which part of the metatarsal bone is fractured, how severe the damage is, and whether it is an acute or stress fracture. Stress fractures normally heal without any complications, and patients are able to return to their previous activities fully. Most metatarsal fractures do not require surgery, but your Raleigh Orthopaedic physician will determine the right treatment plan to ensure that you make a full recovery.
For mild stress fractures, conservative methods such as rest and anti-inflammatory medication can be used to manage symptoms. Non-surgical treatment for a metatarsal fracture includes:
- Rest: Elevate your foot as much as possible
- Anti-inflammatory medication: Medications such as ibuprofen and naproxen can be taken to reduce pain and inflammation.
- Avoid the offending activity: Because stress fractures result from repetitive stress, it is important to avoid the activity that led to the fracture.
- Immobilization, casting, or rigid shoe: A stiff-soled shoe or other form of immobilization may be used to protect the fractured bone while it heals. Use of a postoperative shoe or boot walker is also helpful.
Some acute fractures of the metatarsal bones require surgery, especially if the break is badly displaced. A procedure known as internal fixation can be used to repair the damaged bone. This usually involves inserting pins, plates and/or screws to hold your bones in place while they heal. Recovery from an acute metatarsal fracture generally takes around six to eight weeks.
Recovery Time Following Internal Fixation
It will likely take about twelve weeks to bear full weight on the foot after an internal fixation. When you first return home after surgery, you will require crutches to walk. Keeping the foot elevated above the heart level is also important in the healing process. Resting without much movement is recommended for the first week after surgery.
Can Metatarsal Fractures Be Prevented?
People who are overweight or diabetic are at a higher risk of fracturing their metatarsals. It is important to maintain or work towards a healthy weight and manage diabetes to prevent fractures from happening. Wearing proper footwear while active can also help prevent fractures. The best shoes are ones that fit your feet well and offer plenty of support. Starting a new exercise routine slowly and gradually increasing activity can reduce your risk of fractures as well.
