Chronic Exertional Compartment Syndrome – Diagnosis and Treatment
Diagnosis
Imaging Tests and Scans
Doctors use different scanning tools to help find out why someone has pain in the lower leg, especially if they think it might be chronic exertional compartment syndrome (CECS).
One common tool is magnetic resonance imaging (MRI). This scan gives detailed pictures of the muscles and tissue inside the lower legs. An MRI can help rule out other issues like stress fractures, which can have similar symptoms.
A more advanced kind of MRI measures fluid changes in the muscle compartments. Doctors may ask the patient to move their foot or flex their leg until symptoms appear, and then take another scan.
This process shows any build-up of pressure or swelling that happens when the person is active. Doctors may also use near-infrared spectroscopy (NIRS). This test looks at how much oxygen is in the blood inside the muscles.
They perform it both when the leg is at rest and after the leg has been used. If they find less oxygen during or after exercise, it can mean there is less blood flow in the compartment, which increases the risk for CECS.
This table lists some helpful imaging methods:
Imaging Method | What it Finds | When Used |
---|---|---|
MRI | Muscle structure and fluid | Before and after exercise |
NIRS | Blood oxygen in muscle | Rest and after activity |
X-ray or Bone Scan | Stress fractures | To look for other causes |
Measuring Muscle Pressure
When scans do not show a different cause of leg pain, doctors often use muscle compartment pressure testing to confirm CECS.
The doctor inserts a special needle or small tube to measure the pressure inside the muscle compartment before and after exercise.
Here are some steps in this testing process:
- The patient usually exercises until their usual symptoms begin.
- The doctor quickly measures the muscle pressure at different times, like before exercise, right after, and a few minutes later.
- High pressure can indicate pressure build-up due to CECS.
Even though this test gives reliable results, it can be uncomfortable, so doctors perform it only when other tests point toward chronic exertional compartment syndrome.
Additional Details for Patients
- Chronic compartment syndrome mostly affects the lower legs, causing pain, numbness, or swelling during exercise.
- Symptoms often ease with rest and return when activity starts again.
- The process to find out causes can also help rule out conditions like shin splints or stress fractures.
Treatment
Non-Operative Choices
Doctors often suggest conservative methods first, especially for milder symptoms. These can include rest, reducing or changing activity, and using pain relievers. Physical therapy helps improve movement and supports healing.
Athletes may benefit from custom shoe inserts, changes in running technique, or massage. Some people try botulinum toxin type A injections, though more studies are needed to show how well this treatment works for the condition.
These options usually work only if the triggering activity is stopped or limited.
Surgical Procedures
If non-operative management fails, doctors may advise surgery. Fasciotomy, which involves releasing the thick tissue (fascia) around the muscle to lower pressure, provides an effective solution for ongoing symptoms.
Surgeons may use minimally invasive cuts for faster healing. While most people see improvement, surgery has possible risks, such as infection, numbness, nerve injury, or scarring. Some patients might not get full relief even after surgery.
Key surgical treatment:
Procedure | Description |
---|---|
Fasciotomy | Cutting the fascia to relieve pressure in muscle compartment |
Self-Care Tips
People with chronic exertional compartment syndrome can take steps at home to manage symptoms. Using orthotic supports or choosing high-quality athletic shoes may help prevent pain.
Limiting activities to those that are low-impact, such as bicycling or swimming, allows athletes—including runners and tennis players—to stay active without making injuries worse.
Stretching the affected leg after exercise can also relieve discomfort from repetitive or vigorous movements.
Getting Ready for Your Visit
Steps to Take Before Your Appointment
Planning ahead for your visit helps ensure a productive appointment. When scheduling, check if you need to follow any instructions, such as fasting or bringing certain documents.
Gather information about your symptoms—even minor details—as they could be important for diagnosis.
Write down any changes or patterns in your symptoms, including when they started and what makes them better or worse. Note how often and how intensely you exercise, and mention any sports or activities you do regularly.
Create a list of all the medications, vitamins, and supplements you take, including how much you take of each. Having these details ready helps your doctor get the full picture.
Bring copies of any imaging tests or reports you have had previously. If possible, contact your doctor’s office to find out how to share these records before your appointment.
If you feel nervous or want extra support, ask a family member or friend to go with you. They can help remember instructions or details discussed during your visit.
Beforehand, write down any questions you want to ask. Questions might include:
- What might be causing these symptoms?
- Are there any other possible explanations?
- What tests will I need?
- Is this condition likely to last a long time?
- What treatments are available, and which are best for me?
- Do I need to avoid certain activities?
- Should I see a specialist? Whom would you suggest?
Add any other concerns or questions you may have to your list. This helps you make the most of your appointment.

What Your Healthcare Provider May Ask
During your appointment, the provider will likely ask many questions to better understand your condition.
Being ready for these can help the visit run smoothly and ensure all important information is shared.
They may inquire about:
- The time symptoms began
- Whether symptoms come and go or stay
- The level of discomfort or pain
- What reduces or worsens the symptoms
- How quickly symptoms appear after starting activity
- How long it takes for symptoms to go away after stopping
You might also be asked about any weakness, tingling, or numbness in your legs or feet. These details aid in finding the best way to assess and treat the issue.
Feel free to give detailed answers and mention anything unusual. Your doctor may use this information to determine if you need further tests, refer you to another specialist, or recommend specific next steps.
Medical attention in these appointments focuses on getting a clear view of your health. Honest, complete answers help your healthcare team provide the right advice and care based on your needs.
Further Details
Acute compartment syndrome happens when increased pressure in a muscle compartment blocks blood flow.
This can stop oxygen and nutrients from reaching the tissues. It often occurs after an injury, such as a fracture or heavy blow, and can quickly become a medical emergency.
Without quick treatment, tissue damage may be permanent.
Key points to understand:
- Blood Flow: When blood can’t move properly through a compartment, the tissues are deprived of oxygen.
- Nutrients: The lack of circulation prevents important nutrients from reaching muscles and nerves.
- Bleeding: Internal bleeding from trauma can raise pressure, increasing the risk of compartment syndrome.
- Medical Attention: Acute cases need immediate care, often with surgery to relieve pressure and restore normal circulation.
Symptom | Possible Cause | Results |
---|---|---|
Severe pain | High pressure in muscles | Tissue damage |
Numbness or weakness | Blocked nerves & vessels | Loss of function |
Swelling or tightness | Bleeding or fluid buildup | Increased compartment pressure |
Prompt treatment is important to prevent lasting harm.
