The pressure point at which fasciotomy should be considered is not a specific value, although a compartment pressure of 30 mm Hg is a commonly cited value. Masquelet notes that whenever diastolic pressure minus tissue pressure (Δ p) is less than 30 mm Hg, fasciotomy is indicated.

When is a fasciotomy performed?

A fasciotomy is an emergency procedure used to treat acute compartment syndrome. Compartment syndrome is when the pressure builds up in a non-compliant osseofascial compartment and causes ischemia leading to muscle and nerve necrosis.

What are the indications for fasciotomy?

The indications for fasciotomy were warm ischemia time greater than 6 hours and clinical evidence of compartment syndrome or elevated compartment pressures (>35 mm Hg).
