MESS Score (Mangled Extremity Severity Score)

Predicts likelihood of successful limb salvage vs amputation in mangled lower extremity injuries. In Johansen's two series (1990) a MESS of 7 or more predicted amputation with 100% accuracy.

Score interpretation

MESS < 7 — Limb salvage may be successful

→ Attempt limb salvage with vascular reconstruction and orthopaedic stabilisation

MESS >= 7 — Primary amputation predicted

→ High likelihood amputation needed; early discussion with patient; involve vascular and orthopaedics

Interpretation bands for the MESS Score. Apply clinical judgement and local guidance.
