In suspected acute compartment syndrome, what is the emergent treatment?

• A. Bed rest and analgesics
• B. Elevation only
• C. Physical therapy
• D. Emergent fasciotomy

Answer: (D)

The key idea is that suspected acute compartment syndrome needs immediate relief of rising pressure to restore blood flow to the muscles and nerves. When the pressure within a closed fascial compartment becomes high enough, perfusion drops, leading to muscle necrosis and nerve injury if not treated promptly. Emergent fasciotomy directly relieves that pressure by cutting the fascia and decompressing the affected compartments, which can prevent irreversible damage when time is critical. Nonoperative options like bed rest and analgesics do nothing to lower the intracompartment pressure, and delaying decompression allows ischemia to progress. Elevating the limb is not a reliable treatment and can reduce arterial inflow if taken too far. Physical therapy is inappropriate in the acute setting because the goal here is rapid decompression, not rehabilitation. If clinical suspicion is high, proceeding to fasciotomy rapidly is the best course to protect the limb.
