Compartment Syndrome is a serious medical condition that occurs when excessive pressure builds up within the muscles. This pressure reduces blood flow, depriving muscles and nerves of oxygen and nutrients. If not treated promptly, it can lead to permanent muscle and nerve damage, disability, or even the need for amputation. Understanding the warning signs and knowing when to seek emergency care can make a life-saving difference.

This detailed guide explains everything you need to know about Compartment Syndrome — from causes and risk factors to diagnosis, treatment options, and prevention.

What Is Compartment Syndrome?

Your arms and legs are divided into sections called compartments, which contain muscles, nerves, and blood vessels. These compartments are surrounded by a tough tissue layer called fascia. Unlike other tissues, fascia does not stretch easily.

When swelling, bleeding, or inflammation occurs inside a compartment, the pressure increases. Since the fascia cannot expand, the rising pressure squeezes nerves and blood vessels, disrupting blood flow. This condition is known as Compartment Syndrome.

There are two types:

1. Acute Compartment Syndrome (ACS)

• A medical emergency

• Occurs suddenly after trauma or injury

• Requires immediate surgical treatment

• If not treated within 6 hours, the damage can be irreversible

2. Chronic Exertional Compartment Syndrome (CECS)

• Develops gradually, often in athletes

• Caused by repetitive exercise

• Not life-threatening but can affect performance and daily functioning

Causes of Compartment Syndrome

1. Traumatic Injuries (Most Common Cause)

Acute Compartment Syndrome is usually triggered by:

• Fractures (especially of tibia or forearm)

• Crush injuries

• Severe bruising or blunt trauma

• Tight casts or bandages

• Surgery (post-operative swelling)

2. Overuse and Exercise

Chronic Compartment Syndrome is common in:

• Runners

• Cyclists

• Military recruits

• Sports involving repetitive leg or arm movements

3. Internal Bleeding

Conditions that cause bleeding inside the compartment:

• Ruptured blood vessels

• Excessive use of anticoagulants (blood thinners)

• Hemophilia

4. Burns

Burns cause tightening of skin and tissue, increasing pressure in the compartment.

5. Steroid Use

Long-term or improper steroid use may cause muscle edema and increase compartment pressure.

How Compartment Syndrome Develops: The Physiology

When muscle swells due to injury or inflammation, the blood vessels inside the compartment collapse under pressure. This prevents oxygen-rich blood from reaching tissues. When oxygen supply drops:

• Muscles begin to die within hours

• Nerves stop functioning

• Toxins build up in the affected area

• Permanent disability may occur

In severe cases, untreated ACS can even lead to kidney failure due to muscle breakdown releasing toxins (rhabdomyolysis).

Symptoms of Compartment Syndrome

Acute Compartment Syndrome (Emergency Symptoms)

Symptoms usually appear within a few hours of the injury:

1. Severe Pain

• Intense, constant, and disproportionate to injury

• Worsens with stretching of the muscle

2. Tightness or Fullness

• A feeling of extreme pressure in the affected limb

3. Numbness or Tingling

• Indicating nerve compression

4. Pale or Cool Skin

• Due to reduced blood circulation

5. Weakness or Paralysis

• Late-stage sign — requires emergency action

Chronic Exertional Compartment Syndrome Symptoms

Typically occur during exercise and improve with rest:

• Gradual, aching pain

• Tightness or cramping

• Numbness or tingling

• Muscle weakness

• Visible bulging of muscles in severe cases

Common Locations of Compartment Syndrome

While it can occur anywhere, the most affected areas include:

1. Lower Leg (Most Common Site)

Divided into:

• Anterior compartment

• Lateral compartment

• Deep posterior compartment

• Superficial posterior compartment

2. Forearm

Particularly after fractures or crush injuries.

3. Thigh

4. Foot or Hand

Often due to trauma or burns.

Diagnosis of Compartment Syndrome

1. Physical Examination

Doctors check for:

• Severe pain

• Tightness of the skin

• Tenderness

• Sensory loss

• Weakness

2. Compartment Pressure Monitoring (Gold Standard)

A special device measures internal pressure. High pressures confirm the diagnosis.

3. Imaging Tests

Used mainly to rule out other conditions:

• X-ray (for fractures)

• MRI (to check tissue swelling)

• Doppler ultrasound (to check blood flow)

4. Blood Tests

To detect muscle damage:

• Creatine kinase (CK)

• Myoglobin levels

For chronic cases:

• Pressures are measured before and after exercise.

Treatment of Compartment Syndrome

Acute Compartment Syndrome Treatment

Acute cases require immediate surgical intervention.

1. Emergency Fasciotomy (Life-Saving Surgery)

A surgeon makes long cuts through the skin and fascia to release pressure. This restores blood flow and prevents muscle death.

Delayed treatment can lead to:

• Permanent nerve damage

• Muscle scarring (contracture)

• Loss of limb function

• Amputation

2. Supportive Treatments

After fasciotomy:

• Wound care

• Antibiotics to prevent infection

• Pain management

• Physiotherapy for mobility recovery

Chronic Exertional Compartment Syndrome Treatment

1. Conservative Management

• Activity modification

• Proper warm-up and stretching

• Use of orthotics or shoe inserts

• Physical therapy

• Anti-inflammatory medications

2. Surgical Fasciotomy

Recommended if conservative methods fail. Many athletes return to full activity post-surgery.

Complications of Untreated Compartment Syndrome

If not treated on time, complications can be severe:

1. Permanent Muscle Damage

Muscles may harden and shorten (Volkmann’s contracture).

2. Nerve Injury

Causing chronic pain or paralysis.

3. Infection

Especially in open fasciotomy wounds.

4. Amputation

In extreme cases where tissue death occurs.

5. Kidney Failure

Due to toxins released from dying muscles (rhabdomyolysis).

Prevention of Compartment Syndrome

While not all cases can be prevented, you can reduce the risk:

1. For Traumatic Causes

• Avoid overly tight bandages or casts

• Elevate limbs after injury (not too high)

• Seek immediate medical care after fractures

2. For Exercise-Related Causes

• Gradually increase workout intensity

• Wear proper footwear

• Warm up and stretch before exercise

• Stay hydrated during sports

3. For People on Blood Thinners

• Regular monitoring

• Report any bruising or swelling promptly

Compartment Syndrome in Athletes

Athletes are particularly prone to CECS due to repetitive stress. Warning signs include:

• Pain starting after a certain distance or duration

• Improvement quickly after rest

• Tightness during exercise

Ignoring these signs can worsen the condition. Proper evaluation and timely treatment help athletes return to peak performance safely.

Compartment Syndrome in Children

Though less common, it can occur due to:

• Fractures (especially elbow or forearm)

• Burns

• Rarely, infections

Children may not express pain clearly. Warning signs include:

• Excessive crying

• Refusal to move limb

• Swelling or tightness

Early diagnosis is essential to prevent long-term problems.

Recovery After Fasciotomy

Recovery depends on:

• Severity of injury

• Time to treatment

• Extent of muscle damage

Typical recovery timeline

• Pain and swelling reduce in 1–2 weeks

• Stitches removed in 2–3 weeks

• Light activity resumes in 4–6 weeks

• Full recovery may take 3–6 months

Physiotherapy helps restore strength and flexibility.

When to Seek Emergency Medical Care

Visit an emergency centre immediately if you experience:

• Severe pain after injury

• Pain worse than expected for the condition

• Pain when stretching the muscle

• Persistent numbness or tingling

• Tight, shiny, hard-looking skin

Early intervention can save the limb — and sometimes even your life.

Frequently Asked Questions (FAQ)
