Stress Fracture

Article by J.Miller, Z.Russell

What is a Stress Fracture?

One of the most common injuries in sport is a stress fracture. Stress fractures are tiny cracks in a bone. The repetitive application of force causes stress fractures through the bone that isn’t strong enough. Essentially, the bone is weaker than is required for the activity demands or exercise intensity.

The most common stress fractures occur in runners, but stress fractures can occur due to your sport’s demands. e.g. lumbar spine stress fractures in gymnasts and cricket bowlers. Common running stress fractures include foot (navicular, metatarsal), tibia (shin splints).

Stress fractures can also arise from the everyday use of a bone weakened by a condition such as osteoporosis. Overcoming an injury like a stress fracture can be difficult because they usually occur in very active people who hate not to exercise!

Stress Fractures occur in 2 scenarios:

  1. Excessive force through normal bone
  2. Excessive force through abnormal bone, e.g. Osteoporosis

Stress fractures are most common in the weight-bearing bones of the lower leg and foot. Track and field athletes are particularly susceptible to stress fractures, but anyone can experience a stress fracture. If you’re starting a new exercise program, for example, you may be at risk if you do too much too soon.

What Causes a Stress Fracture?

A stress fracture is an overuse injury. It occurs when muscles become fatigued and are unable to absorb added shock. Eventually, the fatigued muscle transfers the stress overload to the bone, causing a tiny crack called a stress fracture.

Stress fractures often are the result of increasing the amount or intensity of an activity too rapidly. They can also be caused by an unfamiliar surface’s impact (e.g. a runner who has switched surfaces from grass to concrete).
Other stress fracture causes include improper equipment (a runner using too rigid or too flexible shoes) and increased physical stress (a player who has had a substantial increase in playing time).

Where do Stress Fractures occur?

Most stress fractures occur in the weight-bearing bones of the lower leg and the foot. More than 50 per cent of all stress fractures occur in the lower leg. Common sites include:

What Activities are susceptible to Stress Fracture?

Sports that involve the repeated impacts of running and landing are vulnerable to stress fractures.

Studies have shown that athletes participating in tennis, track and field, gymnastics, and basketball are very susceptible to stress fractures. In all of these sports, the repetitive stress of the foot striking the ground can cause trauma.

Without sufficient rest between workouts or competitions, an athlete is at risk of developing a stress fracture.

Are Women More Susceptible to Stress Fractures?

Stress fractures affect people of all ages who participate in repetitive sporting activities, like running. Studies have shown that female athletes seem to experience more stress fractures than their male counterparts.

We attribute this higher incidence to a condition referred to as “the female athlete triad”:

  • eating disorders (bulimia or anorexia),
  • amenorrhea (infrequent menstrual cycle), and
  • osteoporosis (reduced bone density).

As a female’s bone mass decreases, her chances of a stress fracture developing increase. The advice of a sports dietitian is highly recommended.

What are the Symptoms of a Stress Fracture?

  • Pain with activity is the most common complaint with a stress fracture.
  • This pain subsides with rest.

How are Stress Fractures Diagnosed?

During your examination, your health practitioner must evaluate the patient’s risk factors for stress fracture. X-rays may determine stress fracture. Sometimes, the stress fracture cannot be seen on regular x-rays or will not show up for several weeks after the pain starts.

Occasionally, a computed tomography (CT) scan or magnetic resonance imaging (MRI) will be necessary. MRI is the most specific and sensitive test available. A bone scan will identify “hot spots”, which may indicate stress fractures or tumours etc.

How are Stress Fractures Treated?

The most important treatment is rest. Individuals need to rest from the activity that caused the stress fracture and engage in a pain-free activity during the six to eight weeks; it takes most stress fractures to heal. If the activity that caused the stress fracture is resumed too quickly, larger, harder-to-heal stress fractures can develop. Re-injury also could lead to chronic problems where the stress fracture might never heal properly. While you are resting from your sport, it is wise to screen for predisposing factors. We recommend a team injury management approach.

  • Sports Physician or Doctor to address bone density, hormonal issues, calcium, Vitamin D etc
  • Physiotherapist for whole lower limb and core muscle and joint function
  • Orthopaedic Surgeon for surgical intervention if required.
  • Sports Dietitian to ensure adequate nutrition.
  • Podiatrist for foot biomechanics assessment
  • Psychologist to assist with return to sport issues

How to Prevent Stress Fractures

  • When participating in any new sports activity, set incremental goals. For example, do not immediately set out to run five kilometres a day; instead, gradually build up your mileage every week. Use the 10% rule.
  • Cross-training — alternating activities that accomplish the same fitness goals — can prevent injuries like stress fractures. Instead of running every day to meet cardiovascular goals, run on even days and bike on odd days. Add some strength training and flexibility exercises to the mix for the most benefit.
  • Maintain a healthy diet. Make sure you incorporate calcium- and vitamin D-rich foods in your meals. Be guided by your Sports Dietitian.
  • Use the proper equipment. Do not wear old or worn running shoes. Be guided by your podiatrist.
  • Undertake a Musculoskeletal Screening performed by your Sports Physiotherapist.
  • If pain or swelling occurs, immediately stop the activity and rest for a few days. If continued pain persists, see an orthopaedic surgeon.
  • It is important to remember that you can return to sports at your normal playing level if you recognise the symptoms early and treat them appropriately.

Elite Sports Injury Management

You probably already know that a sports injury can affect not only your performance but also your lifestyle. The latest research continues to change sports injury management considerably. Our challenge is to keep up to date with the latest research and put them to work for you.

How we treated you last year could vary significantly from how we treat you this year. The good news is that you can benefit considerably from our professional knowledge.

What Should You Do When You Suffer a Sports Injury?


Rest from painful exercise or a movement is essential in the early injury stage. "No pain. No gain." does not apply in most cases. The rule of thumb is - don't do anything that reproduces your pain for the initial two or three days. After that, you need to get it moving, or other problems will develop.

Ice or Heat?

We usually recommend avoiding heat (and heat rubs) in the first 48 hours of injury. The heat encourages bleeding, which could be detrimental if used too early. In traumatic injuries, such as ligament sprains, muscle tears or bruising, ice should help reduce your pain and swelling.

Once the "heat" has come out of your injury, you can use heat packs. We recommend 20-minute applications a few times a day to increase the blood flow and hasten your healing rate. The heat will also help your muscles relax and ease your pain. If you're not sure what to do, please call us to discuss your situation specifically.

Should You Use a Compressive Bandage?

Yes. A compressive bandage will help to control swelling and bleeding in the first few days. In most cases, the compressive dressing will also help support the injury as you lay down the new scar tissue. This early healing should help to reduce your pain. Some injuries will benefit from more rigid support, such as a brace or strapping tape. Would you please ask us if you are uncertain about what to do next?


Gravity will encourage swelling to settle at the lowest point. Elevation of an injury in the first few days is beneficial, especially for ankle or hand injuries. Think where your damage is and where your heart is. Try to rest your injury above your heart.

What Medication Should You Use?

Your Doctor or Pharmacist may recommend pain killers or an anti-inflammatory drug. It is best to seek professional advice as certain medications can interfere with other health conditions, especially asthmatics.

When Should You Commence Physio?

In most cases, "the early bird gets the worm". Researchers have found that the intervention of physiotherapy treatment within a few days has many benefits. These include:

  • Relieving your pain quicker via joint mobility techniques, massage and electrotherapy
  • Improving your scar tissue using techniques to guide the direction it forms
  • Getting you back to sport or work quicker through faster healing rates
  • Loosening or strengthening of your injured region with individually prescribed exercises
  • Improving your performance when you return to sport - we'll detect and help you correct any biomechanical faults that may affect your technique or predispose you to injury.

What If You Do Nothing?

Research tells us that injuries left untreated take longer to heal and have lingering pain. They are also more likely to recur and leave you with either joint stiffness or muscle weakness. It's important to remember that symptoms lasting longer than three months become habitual and are much harder to solve. The sooner you get on top of your symptoms, the better your outcome.

What About Arthritis?

Previously injured joints can prematurely become arthritic through neglect. Generally, there are four main reasons why you develop arthritis:

  • An inappropriately treated previous injury (e.g. old joint or ligament sprains)
  • Poor joint positioning (biomechanical faults)
  • Stiff joints (lack of movement diminishes joint nutrition)
  • Loose joints (excessive sloppiness causes joint damage through poor control)

What About Your Return to Sport?

Your physiotherapist will guide you safely back to the level of sport at which you wish to participate. If you need guidance, ask us.

What If You Need Surgery or X-rays?

Not only will your physio diagnose your sports injury and give you the "peace of mind" associated, but they'll also refer you elsewhere if that's what's best for you. Think about it. You could be suffering needlessly from a sports injury. Would you please use our advice to guide you out of pain quicker? And for a lot longer.

If you have any questions regarding your sports injury (or any other condition), don't hesitate to get in touch with your physiotherapist to discuss. You'll find our friendly staff happy to point you in the right direction.

Sports injuries do differ from common everyday injuries. Athletes usually require high-level performance and demand placed upon their body, which stresses their muscles, joints and bones to the limit. Sports physiotherapists help athletes recover from sporting injuries and provide education and resources to prevent problems.

Each sports physiotherapist usually has sport-specific knowledge that addresses acute, chronic and overuse injuries. Their services are generally available to sportsmen and women of all ages engaged in sports at any level of competition.

Members of Sports Physiotherapy Australia (SPA) have experience and knowledge of the latest evidence-based practice, professional assessment and diagnosis of sports injuries, and effective hands-on management techniques and exercise protocols to assist recovery and prevent future damage. SPA members have access to the most recent advances in sports physiotherapy. You'll be pleased to know that most PhysioWorks physiotherapists and massage therapists have a particular interest in sports injury management.
