Stress Fracture of the Calcaneus

A calcaneal stress fracture is a fine crack in the heel bone caused by repetitive overload. At ACE Physio Sports, we ensure safe bone healing and a structured return to impact activities through precision load management.

Stress Fracture of the Calcaneus

A calcaneal stress fracture occurs when the heel bone is subjected to repetitive mechanical stress that exceeds its ability to repair and remodel. This is a common injury among runners and military personnel. At ACE Physio Sports, we provide expert clinical guidance on non-weight-bearing periods and phased transition back to weight-bearing activities via our website: https://acephysiosport.com

Causes

The injury is almost always the result of a sudden increase in physical load. Triggers include: • Rapidly increasing weekly running mileage or intensity • Transitioning to 'minimalist' footwear or running on harder surfaces • Changing to a running gait that increases heel-strike impact • Underlying nutritional deficiencies or hormonal imbalances affecting bone density • Poor biomechanical alignment of the foot and ankle joint

Symptoms

Unlike an acute break, the pain starts as a dull ache that progressively worsens. Many runners find: • Deep pain in the heel that intensifies during weight-bearing activity • Sharp discomfort when squeezing the back of the heel from both sides • Pain when walking that forces you to limp or avoid landing on the heel • An inability to put weight down comfortably when first waking up • Localized swelling and tenderness along the sides of the calcaneus

What should I do?

The first step is immediate off-loading. You must avoid high-impact activities (running, jumping) until a clinical assessment and imaging (such as an MRI) confirm the diagnosis. Implementing a period of 'non-impact' cross-training like swimming can help maintain fitness during healing.

What shouldn’t I do?

Do not 'test' the heel by trying to run through the pain, as this can turn a stress fracture into a complete bone break. Avoid wearing flat, unsupportive shoes that provide no cushioning; explore support options at https://acephysiosport.com.

Physiotherapy treatment

At ACE Physio Sports, our clinical focus is on protective healing and biomechanical correction: • Load Management Education: Training you how to gradually re-introduce weight-bearing without re-injuring the bone. • Gait Analysis: Specialized assessment near East Coast Road to identify and correct running patterns that overload the heel. • Footwear Optimization: Advising on the best orthotic support and cushioned shoes for your recovery. • Strengthening the 'Foot Core': Building the small muscles of the foot to provide better natural shock absorption.

Recovery / long-term effects

Bone healing typically takes 6 to 8 weeks of reduced activity. A return to full running often takes 3 to 4 months of structured progression. If the underlying cause is not addressed, the risk of recurrence is high.

Frequently Asked Questions

How do I know if I have a stress fracture?

A stress fracture causes a deep, aching foot pain that worsens progressively with activity and improves with rest. It's common in runners and athletes who suddenly increase training load. A physio assessment and imaging (MRI or bone scan) can confirm the diagnosis.

How long does a Foot stress fracture take to heal?

Most stress fractures heal within 6–12 weeks with proper rest and load management. Physiotherapy guides a graded return to activity once the bone has healed, and addresses contributing factors such as training errors, footwear, or muscle imbalances.

Can I continue training with a stress fracture?

High-impact activities like running must be stopped to allow healing. However, your physiotherapist can prescribe low-impact cross-training options to maintain fitness while the bone recovers. A structured return-to-running plan follows once you're cleared.
