Compartment syndrome is a pathological condition that results from an excessive increase in pressure within a muscle compartment. The elevated pressure compromises blood flow, thereby impairing the delivery of nutrients and oxygen to muscle and nerve cells. The condition is extremely painful and, in severe cases, may lead to permanent damage of the affected muscles and nerves.
Compartment syndrome is classified into two main types:
- Acute Compartment Syndrome (ACS): This form typically occurs following a severe traumatic injury. It constitutes a medical emergency, as delayed treatment can result in irreversible muscle and nerve damage.
- Chronic (Exertional) Compartment Syndrome (CECS): This type is associated with intense or repetitive physical activity. It is not considered an emergency, and its hallmark symptom is pain that worsens during muscle exertion and subsides with rest.
Etiology
The causes of compartment syndrome vary depending on its type.For acute compartment syndrome (ACS), the most significant causes include:
- Severe trauma (e.g., from a motor vehicle accident or a fall)
- Fracture
- Crush injuries
- Reperfusion injury following restoration of blood flow after prolonged vascular occlusion
- Use of anabolic steroids
- Tightly applied casts or splints
In the case of chronic (exertional) compartment syndrome (CECS), the main predisposing factors are:
- Excessive exertion during physical activity
- Participation in sports involving repetitive movements, such as running or cycling
Symptoms
The symptoms of compartment syndrome differ according to whether the condition is acute or chronic.Typical symptoms include:
- Severe pain, particularly during passive stretching of the affected muscles
- Numbness, tingling, or a burning sensation
- Hypoesthesia or paralysis, which may indicate permanent neuromuscular damage
Chronic (Exertional) Compartment Syndrome.Typical symptoms include:
- Pain during exercise that subsides with rest
- Muscle cramps during physical activity
- Numbness
- Difficulty walking or performing activity
- Visible swelling of the affected muscles
Management
The management of compartment syndrome may be either conservative or surgical, depending on the type and severity of the condition.However, acute compartment syndrome (ACS) constitutes a true surgical emergency and can only be treated effectively through fasciotomy — a procedure involving the surgical decompression of the affected muscle compartments by incising the fascia.Due to tissue swelling, wound closure is typically performed at a later stage, once the edema subsides.In contrast, chronic (exertional) compartment syndrome (CECS) can initially be managed conservatively, with treatment options including:
- Physiotherapy program focused on stretching and strengthening
- Pharmacological therapy with anti-inflammatory medications
- Use of orthotic insoles to improve biomechanics and reduce stress on the affected compartments
If conservative measures fail to provide adequate symptom relief, surgical intervention may be indicated.In such cases, a minimally invasive fasciotomy is performed through a small incision, allowing decompression of the affected compartments.This approach generally enables a faster recovery compared to the procedure required for acute compartment syndrome.
