Leg injuries can significantly impact daily life and mobility. Understanding fibula fractures is important for effective recovery. This article clarifies common questions about these injuries and the appropriate steps to take.
Can You Walk on a Fractured Fibula?
While some individuals might physically be able to put weight on a fractured fibula, it is generally not advised. The fibula, the smaller of the two lower leg bones, plays a minimal role in bearing the body’s weight, accounting for only about 5% to 17% of the load. The larger tibia carries the majority. Even with minor stress fractures or stable breaks, the ability to walk does not mean it is safe or without risk of further injury.
Why Walking on a Fractured Fibula is Risky
Continued weight-bearing on a fractured fibula can lead to several negative outcomes, potentially worsening the injury and delaying healing. Putting pressure on the injured bone can cause further displacement of bone fragments, possibly necessitating surgery to realign them. This can also damage surrounding soft tissues, including ligaments, nerves, and blood vessels, leading to increased pain, swelling, and potential long-term complications like chronic pain or joint stiffness. In severe cases, walking on an untreated fracture can result in malunion, where the bone heals incorrectly, or nonunion, where bones fail to heal together, permanently impairing function and leading to early onset ankle arthritis.
Recognizing a Fibula Fracture
A fibula fracture presents with several signs and symptoms. Pain is a primary indicator, often worsening when attempting to bear weight on the affected leg. Swelling and tenderness around the injury site are common, along with visible bruising from internal bleeding. Individuals might experience difficulty moving their ankle or foot, and sometimes a visible deformity or bump may be present on the lower leg. Tingling or numbness in the foot could also occur if there is nerve involvement, signaling a more serious injury.
What to Do After a Suspected Fracture
If a fibula fracture is suspected, seeking prompt medical attention is necessary to prevent further complications and ensure proper healing. A healthcare provider will conduct a physical examination and may order imaging tests like X-rays, MRI, or CT scans to accurately diagnose the injury and determine its severity. While awaiting medical evaluation, initial first aid measures can help manage symptoms. Applying the RICE protocol can help reduce pain and swelling:
- Rest: Avoid any weight on the injured leg.
- Ice: Helps minimize inflammation.
- Compression: An elastic bandage can control swelling.
- Elevation: Raising the leg above heart level promotes fluid drainage.
These measures are temporary and not a substitute for professional medical assessment and treatment.
