Which combination of signs indicates acute limb compartment syndrome and necessitates urgent fasciotomy?

Acute limb compartment syndrome is a surgical emergency where rising pressure in a closed muscle compartment cuts off blood flow and damages muscle and nerve. The key signs that indicate this urgent situation are severe, constant pain that is out of proportion to exam and worsens with passive stretching of the muscle, early sensory changes such as paresthesias, and pallor from reduced perfusion. When these signs are present, urgent fasciotomy is needed to relieve the pressure and prevent irreversible damage. The described combination matches this pattern: severe pain out of proportion, pain with passive stretch, paresthesias, pallor, and the need for immediate decompression. Other options miss this characteristic pain pattern or refer to unrelated/systemic findings, so they don’t indicate ACS.
