What is the key finding of compartment syndrome?

• A. Significant increased pain due to constriction and loss of sensation and movement
• B. Mild discomfort that improves with rest
• C. Fever and rash
• D. Hypotension and bradycardia

Answer: (A)

Compartment syndrome centers on dangerously elevated pressure within a closed muscle compartment, which impairs blood flow and nerve function. The hallmark is severe, escalating pain that is out of proportion to exam findings, often accompanied by pain on passive stretching of the affected muscles. As pressure persists, nerves suffer ischemia, leading to sensory changes and weakness or loss of movement if not treated promptly. That is why the described finding—significant increased pain due to constriction along with loss of sensation and movement—is the best answer. The other descriptions don’t fit this condition: mild discomfort that improves with rest doesn’t reflect the intense, progressive pain; fever and rash suggest infection or dermatitis; hypotension and bradycardia point to systemic issues rather than localized limb ischemia.
