Fasciotomy - Surgical Procedure

Medically Reviewed by Dr. Simi Paknikar, MD on May 25, 2017


What is Fasciotomy?

Fasciotomy is a surgical procedure where the fascia is cut to relieve the compartmental pressure in patients with compartment syndrome of the limbs. Fascia is a tough limiting inelastic fibrous membrane that surrounds muscles, nerves and blood vessels and binds them into compartments.

Compartment syndrome is a painful condition with an increase in the pressure of the compartment (muscles, nerves and blood vessels which are covered by fascia) of upper or lower limbs. It leads to a compromise in the blood supply to the muscles and nerves in the compartment and hence reduces the function. The symptoms and signs of compartment syndrome are a disproportionate pain, paresthesia, pain on passive stretching of the muscles, paralysis of muscles, progressive tension in the compartment and pulses are present.

Why is the Fasciotomy Performed?

Fasciotomy is performed to treat a painful condition called compartmental syndrome. Certain conditions like fractures or injury to muscles can increase the pressure within the compartment resulting in compartmental syndrome. The condition compromises blood supply to the muscles, affects the function of nerves in the compartment and injures tissues. The symptoms and signs of compartment syndrome are disproportionate pain, tingling and numbness, pain on passive stretching of the muscles and paralysis of muscles.


Surgical incision or splitting of the fascia reduces the pressure and hence further damage to the structures in the compartment.

What are the Indications of Fasciotomy?

Fasciotomy is performed for the following conditions:

Acute Compartment Syndrome: Fasciotomy helps to salvage the limb in acute cases.

The following are a few causes of acute compartment syndrome:

Chronic Compartment Syndrome: Chronic compartment syndrome is seen among the athletes due to an increase in the muscle mass. It is not an emergency but fasciotomy is necessary if all other conservative measures fail.


A compartment pressure of more than 30mm of Hg is generally considered as an indication for fasciotomy.

What are the Contraindications of Fasciotomy?


Fasciotomy is contraindicated if the diagnosis of the compartment syndrome is made late.

What are the Tests done before Fasciotomy?

The doctor will first confirm the presence of a compartment syndrome through a complete medical history and a physical examination. Acute compartment syndrome is a medical emergency and you may be taken for an operation without any tests. Tests like x-ray or measurement of compartment pressure may be used to confirm the diagnosis of chronic compartment syndrome. Once the surgery is finalized, you will need to undergo certain tests to confirm that you are fit for the surgery. Tests done before fasciotomy may include the following:

What are the Preparations required before Fasciotomy?

Before a planned fasciotomy surgery, you will be advised the following:

What is the Procedure followed for a Fasciotomy Procedure?


Shift to the Operating room - The ambience in the operating room can sometimes be very daunting and a small amount of sedation can help overcome your anxiety. When you are shifted to the operating table, you will see the operating light console and at the head end will be the anesthesia machine. There may also be monitors to check oxygen levels, ECG and other vital parameters. A constant beeping sound may be present from the monitors, which may sometimes be irritating.

Anesthesia before surgery - The fasciotomy surgery is usually performed under general anesthesia due to which you will be asleep during the procedure. Regional anesthesia is also sometimes used, where an anesthetic is injected to numb the entire limb where the surgery is being carried out.

During general anesthesia, the anesthetist will inject drugs through an intravenous line and make you inhale some gases through a mask that will put you in deep sleep. Once you are in deep sleep, a tube will be inserted into your mouth and windpipe to administer the anesthesic gases to overcome pain and keep you comfortable during the surgery.


The limb where the fasciotomy is planned is prepared and draped. A skin incision is made, the underlying fascia is identified and an incision is made on the fascia to relieve the pressure. The location of the incisions depend on the part affected. The wound is not sutured following the fasciotomy and is covered with a dressing.
