Stress Fracture of the Medial Malleolus

What is a stress fracture of the medial malleolus?

The medial malleolus is the bony prominence on the inner side of the ankle. A stress fracture of the medial malleolus is a small crack or incomplete fracture in this bone. Physiotherapy is an effective treatment to support healing, reduce pain, and restore ankle function.

How does a stress fracture of the medial malleolus happen?

Stress fractures occur when there is an imbalance between bone formation and bone resorption (removal). During weight-bearing activities, such as running or jumping, the medial malleolus experiences repeated stress. Normally, the bone adapts by increasing turnover, but if the stress exceeds the bone’s ability to repair itself, tiny cracks can develop, resulting in a stress fracture.

How does a stress fracture of the medial malleolus develop?

When stress is placed on the medial malleolus, small areas of the bone can become damaged. The body resorbs (removes) these damaged areas and replaces them with new bone. If the new bone forms more slowly than the old bone is removed, weak points develop. Repeated stress on these weak areas can lead to a stress fracture.

Recent changes in training—such as increased frequency, duration, intensity, new surfaces, or different footwear—often contribute to the development of a stress fracture.

What are the symptoms of a stress fracture of the medial malleolus?

Stress fractures of the medial malleolus cause gradually increasing pain over several weeks. The pain is usually localized to a specific point on the inner ankle and worsens with exercise. Initially, pain may occur only after activity, but with continued stress, it can develop during exercise, walking, or even at rest. The affected area may also feel tender, red, or warm to the touch. Other symptoms can include:

  • Stiffness in the ankle
  • Muscle spasm
  • Stiffness in the ankle
  • Reduced range of motion
  • Stiffness in the ankle
  • Changes in gait or walking difficulties

What should I do if I have a stress fracture of the medial malleolus?

If you suspect a stress fracture, arrange a physiotherapy assessment as soon as possible. Early diagnosis and treatment are essential to prevent worsening of the fracture and ensure safe healing.

What shouldn’t I do if I have a stress fracture of the medial malleolus?

If you suspect a stress fracture of the medial malleolus, do not continue exercising. A stress fracture is a weak point in the bone, and continued activity can worsen the crack, potentially leading to a larger fracture or a complete bone break. Early rest and professional assessment are essential for safe recovery.

Physiotherapy treatment following a stress fracture of the medial malleolus

Physiotherapy is essential for effective healing. Initially, your physiotherapist will confirm the diagnosis, which may require imaging such as an MRI scan. Based on this, a tailored treatment plan will be developed. Initial management may include:

  • Rest and protection of the ankle, possibly using crutches
  • Ice therapy to reduce pain and inflammation

A programme will be designed to maintain cardiovascular fitness and muscle strength without delaying bone healing. Low-impact activities such as swimming, deep-water running, cycling, and cross-training may be included.

Your physiotherapist will also identify the underlying cause of the stress fracture and address it to prevent recurrence when you return to full activity. Additional treatments may include:

  • Hydrotherapy for gentle strengthening
  • Taping and orthotics to support the ankle
  • Electrotherapy to reduce pain and promote healing

Could there be any long-term effects from a stress fracture of the medial malleolus?

If properly diagnosed and treated, a stress fracture of the medial malleolus usually does not cause long-term problems. Early intervention and addressing the underlying cause are key. Without treatment, there is a risk of a larger crack, a complete fracture, or additional stress fractures when resuming activity.
