Mangled Extremity
Evaluation and management of the severely injured lower extremity
Work through the evaluation of a severely injured extremity, from limb viability assessment and vascular evaluation through salvage-versus-amputation decisions and staged management.
Node Types
- High Priority
- Medium Priority
- Low Priority

Patient presents with severe extremity trauma. Begin systematic evaluation.
Clinical Notes
WTA Critical Decisions Evidence-Based Insights:
- ABC Priority: Avoid Doppler assessment during primary survey - focus on life threats first
- Ischemia Time: Warm ischemia >6 hours significantly reduces salvage success
- Scoring Systems: MESS, PSI, NISSSA, LSI, HFS have NOT proven valid in large prospective studies
- Risk Factors: Age >50, hypotension <90mmHg, Gustilo III B/C, circumferential tissue loss
- Vascular Assessment: ABI <0.9 indicates need for imaging; CTA preferred over angiography
- Family Involvement: Include family in decision-making; consider operative photos for documentation
- Functional Hierarchy: Below-knee > above-knee > hip disarticulation for amputation levels
