What is a stress fracture of the fibula?
The fibula is the smaller of the two bones in the lower leg and runs parallel to the tibia (shin bone). A stress fracture of the fibula refers to a small, incomplete crack or break in the bone, often caused by repetitive stress or overuse. Physiotherapy plays a key role in the recovery process, helping to manage symptoms, promote healing, and prevent recurrence.
How does a stress fracture of the fibula happen?
Stress fractures of the fibula occur when there is an imbalance between bone resorption (breakdown) and bone formation. During activities such as weight-bearing exercise, the fibula experiences repeated loading and responds by increasing bone turnover. This adaptive process allows the bone to remodel and strengthen in response to increased demands. However, if the stress placed on the bone exceeds its ability to repair and rebuild, a stress fracture can develop.
When the fibula is subjected to repeated stress, small areas of the bone may become damaged. These damaged areas are resorbed (broken down) and subsequently replaced with new bone as part of the body’s natural healing process. However, if the rate of new bone formation is slower than the rate of resorption, weakened areas can develop at points of stress within the fibula. Continued stress on these weakened regions can eventually lead to the development of a stress fracture.
A Recent changes in training routines are often key contributors to the development of a stress fracture. These changes may include increased frequency or duration of exercise, greater training intensity, or alterations in training surfaces or footwear.
What are the symptoms of a stress fracture of the fibula?
A stress fracture of the fibula typically causes gradually increasing pain on the outside of the lower leg. In the early stages, this pain is usually only noticeable after activity. However, with continued stress and loading, it can progress to being present during exercise. If left unmanaged, the pain may eventually occur during walking, at rest, and even at night. The area over the fracture site is often tender to touch.
What should I do if I have a stress fracture of the fibula?
If you suspect a stress fracture of your fibula, it is important to arrange a physiotherapy assessment as soon as possible. Early diagnosis and intervention can help prevent the injury from worsening and support a faster recovery.
Physiotherapy treatment for a stress fracture of the fibula.
Physiotherapy plays a key role in the treatment of a stress fracture of the fibula. Initially, your physiotherapist will assess your condition and may refer you for imaging, such as an MRI scan, to confirm the diagnosis. Based on the findings, an individualised treatment plan will be created. Early management often involves a period of rest, the use of a brace or crutches, and ice therapy to reduce pain and inflammation. A rehabilitation programme will be designed to help you maintain cardiovascular fitness and muscle strength without interfering with the healing process. This may include low-impact cross-training activities such as swimming, deep water running, or cycling. Additional treatments may include:
What shouldn’t I do if I have a stress fracture of the fibula?
If you suspect a stress fracture of your fibula, you should stop exercising immediately. Continuing to load the bone may worsen the injury, delay healing, and increase the risk of a complete fibula fracture, potentially leading to a prolonged recovery period.
Could there be any long-term effects from a stress fracture of the fibula?
A stress fracture of the fibula typically does not lead to long-term effects if it is properly treated and the underlying cause is identified and addressed. However, if left unmanaged, there is a risk of a complete fracture or recurrent stress fractures upon returning to activity.
