anterior compartment syndrome

Anterior Compartment Syndrome Description

Anterior compartment syndrome is a painful condition that affects the front part of the lower leg, causing an aching, tight, cramping or squeezing pain [4]. This type of compartment syndrome occurs when the blood supply to the muscle is restricted due to a build-up of pressure inside the muscle compartment [5].

The symptoms of anterior compartment syndrome include:

• Pain on the outside of your shin, specifically on the large muscles called the tibialis anterior [12]
• Weakness in the muscle, making it difficult to pull your foot upwards
• Stretching the tibialis anterior muscle reproduces symptoms
• In severe cases, 'foot drop' may occur, where you are unable to lift your foot off the ground

A doctor may suspect compartment syndrome based on a person's description of symptoms and a physical exam [14]. The diagnosis is often clear from these factors.

Key Points:

• Anterior compartment syndrome causes pain along the front of the lower leg
• Symptoms include pain, weakness, and difficulty lifting the foot
• Diagnosis is made through a combination of symptom description and physical examination

The differential diagnosis of anterior compartment syndrome is broad and includes various conditions that can present with similar symptoms.

Infection-related conditions: Cellulitis, necrotizing fasciitis, and osteomyelitis are all potential causes of anterior compartment syndrome. These infections can lead to increased pressure within the compartment, resulting in impaired local circulation [2].

Neurological conditions: Deep peroneal nerve entrapment is a condition that can mimic the symptoms of anterior compartment syndrome. This occurs when the deep peroneal nerve is compressed or damaged, leading to weakness and sensory loss in the foot [8].

Toxicological conditions: Snake envenomation can also be considered in the differential diagnosis of anterior compartment syndrome. The venom from certain snakes can cause muscle necrosis and increased pressure within the compartment [2].

Vascular conditions: Deep vein thrombosis, ischemic necrosis or gangrene, and popliteal artery entrapment are all potential vascular causes of anterior compartment syndrome. These conditions can lead to impaired circulation and increased pressure within the compartment [2].

Trauma-related conditions: Fractures and other traumatic injuries can also be considered in the differential diagnosis of anterior compartment syndrome. The trauma can cause muscle necrosis and increased pressure within the compartment [4].
