RESUMO
BACKGROUND: The Mangled Extremity Severity Score (MESS) was constructed as an objective quantification criterion for limb trauma. A MESS of or greater than 7 was proposed as a cut-off point for primary limb amputation. Opinions concerning the predictive value of the MESS vary broadly in the literature. The aim of this study was to evaluate the applicability of the MESS in a contemporary civilian Central European cohort. METHODS: All patients treated for extremity injuries with arterial reconstruction at two centres between January 2005 and December 2014 were assessed. The MESS and the amputation rate were determined. RESULTS: Seventy-one patients met the inclusion criteria and could be evaluated for trauma mechanism and injury patterns. The mean MESS was 4.97 (CI 4.4-5.6). Seventy-three per cent of all patients (52/71) had a MESS < 7 and 27% (19/71) of ≥7. Eight patients (11%) underwent secondary amputation. Patients with a MESS ≥ 7 showed a higher, but statistically not significant secondary amputation rate (21.1%; 4/19) than those with a MESS < 7 (7.7%; 4/52; p = 0.20). The area under the ROC curve was 0.57 (95% CI 0.41; 0.73). CONCLUSIONS: Based on these results, the MESS appears to be an inappropriate predictor for amputation in civilian settings in Central Europe possibly due to therapeutic advances in the treatment of orthopaedic, vascular, neurologic and soft-tissue traumas.
