MESS CalculatorBy subhajitmaji43@gmail.com / July 28, 2026 MESS Calculator Calculate the Mangled Extremity Severity Score to evaluate limb salvage vs. amputation. 1. Skeletal / Soft-Tissue Injury Low energy (stab, simple fracture, low-vel gunshot) (+1) Medium energy (open/multiple fractures, dislocation) (+2) High energy (close-range shotgun, high-speed MVA) (+3) Very high energy (crush, severe contamination) (+4) 2. Limb Ischemia Pulsatile but reduced (normal perfusion) (+1) Pulseless, diminished capillary refill (+2) Cool, paralyzed, insensate (+3) Ischemia time > 6 hours (Doubles the ischemia score) 3. Shock (Hemodynamic Status) Normotensive (BP > 90 mm Hg consistently) (+0) Transiently hypotensive in field/ED (+1) Persistently hypotensive (+2) 4. Patient Age Under 30 years (+0) 30 to 50 years (+1) Over 50 years (+2) Calculate MESS Score
