A crushed arm with deformity, swelling, cold and pale, and absent radial pulse; you should be MOST concerned about which condition?

• A. Fracture
• B. Bleeding disorder
• C. Compartment syndrome
• D. Tendon rupture

Answer: (C)

Compartment syndrome is the concern here. A crush injury with deformity and swelling can raise pressure inside the muscle compartments. When swelling is trapped by the tough fascia, the rising pressure compromises blood flow to the limb. The limb becoming cold and pale and the absence of the radial pulse indicate that perfusion is severely reduced, which can lead to tissue death if not treated promptly. This situation is more urgent than a simple fracture, a bleeding disorder, or a tendon rupture because it threatens the viability of the entire limb. In practice, treat this as an emergency: immobilize the arm and keep it at heart level, remove any restrictive jewelry or dressings, and transport quickly while monitoring neurovascular status. Do not delay for additional tests if compartment syndrome is suspected; rapid hospital evaluation is needed for potential fasciotomy to relieve the pressure.
