Which finding is NOT considered an early sign of compartment syndrome?

• A. Increased pain out of proportion
• B. Pain on passive stretch
• C. Absent distal pulses
• D. Palpable tenseness

Answer: (C)

Early compartment syndrome shows up with pain that’s out of proportion to exam findings and pain on passive stretch of the muscles, along with a tense, swollen compartment. These reflect rising pressure affecting nerves and muscles before arterial flow is critically lost. Absent distal pulses, on the other hand, is a late sign; arteries may still be delivering blood even when the pressure is high, so a pulse being present doesn’t rule out the problem, and a lost pulse indicates more advanced ischemia and tissue threat. So the finding that is not an early sign is the absence of distal pulses.
