5th Metatarsal Fracture

A 5th metatarsal fracture is a common injury that affects the foot, specifically the long bone on the outside of the foot that connects to the smallest toe.  X-rays are often used to make a diagnosis of 5th metatarsal fracture.  This article will discuss the causes, symptoms, and treatments of this injury.

Causes of 5th Metatarsal Fracture

5th metatarsal fractures can result from various situations, including direct impact, overuse, or awkward landings. Sports that involve jumping, running, or rapid directional changes are particularly high-risk activities for this type of injury. Accidents, such as dropping a heavy object on the foot or stepping awkwardly on uneven ground, can also lead to fractures of the 5th metatarsal.

Symptoms of 5th Metatarsal Fracture

Identifying a 5th metatarsal fracture early is important for effective treatment. The most common symptoms include pain, swelling, and bruising around the outer foot. Some people may also experience difficulty walking or bearing weight on the affected foot. The pain typically intensifies with activity and may slightly improve with rest.

Imaging and Diagnosis of 5th Metatarsal Fracture

Imaging is a crucial component in diagnosing and managing a 5th metatarsal fracture. Accurate imaging not only confirms the presence of a fracture but also provides details about its location, alignment, and severity, which are important for formulating an effective treatment plan. Here’s a deeper look into the types of imaging used for this condition and how they contribute to patient care.

X-rays: The First Line of Imaging

X-rays are the primary imaging technique used to diagnose 5th metatarsal fractures. They are quick, widely available, and cost-effective. An X-ray will typically show the location of the fracture along the metatarsal and can help differentiate between a simple, non-displaced fracture and more complex forms, such as those involving displacement or multiple fragments.

When performing an X-ray, multiple angles may be used to ensure a complete view of the metatarsal.  These different views help in assessing the alignment of the bone fragments and the stability of the fracture, which are important for deciding whether surgical or non-surgical treatment is appropriate.

CT Scans

In cases where X-ray results are inconclusive or when the complexity of the fracture requires more detailed visualization, a Computed Tomography (CT) scan may be recommended. CT scans offer a more detailed image of the bone structure by combining multiple X-ray images taken from different angles, creating cross-sectional views of the foot.

This advanced imaging method is particularly useful for identifying the exact pattern of the fracture and for planning surgical interventions, if necessary. It can reveal details about bone fragments and the surrounding soft tissue.

MRI: Assessing Soft Tissue Damage

Magnetic Resonance Imaging (MRI) is not typically the first choice for imaging bone fractures, but it is helpful in assessing associated soft tissue injuries, which can occur with 5th metatarsal fractures. MRI can provide detailed images of ligaments and tendons.

Importance of Accurate Imaging

Accurate imaging is critical in the treatment of a 5th metatarsal fracture. It not only confirms the diagnosis but also influences the treatment strategy. For instance, non-displaced fractures can often be treated conservatively with immobilization, while displaced or complicated fractures may require surgical treatment.

Treatment Options for 5th Metatarsal Fracture

Treatment for a 5th metatarsal fracture varies depending on the severity and type of the fracture. Minor fractures may necessitate immobilization with a cast or a boot to allow the bone to heal properly. In some cases, especially when the fracture is displaced, surgical intervention may be required to realign and stabilize the fracture.


A 5th metatarsal fracture is a significant injury that requires timely and appropriate care. Recognizing the symptoms early and utilizing proper imaging techniques are essential steps in accurately diagnosing and treating this type of fracture. With the right treatment and rehabilitation, most individuals can expect a full recovery and return to their normal activities. If you suspect you have a fracture, consult a healthcare provider to get the appropriate diagnosis and treatment plan.
