Mangled extremity severity score: an accurate guide to treatment of the severely injured upper extremity.
The mangled extremity severity score (MESS) is a scoring system that can be applied to mangled extremities and help one determine which mangled limbs will eventually come to amputation. The MESS is a graduated grading system based on skeletal and soft tissue injury, shock, ischemia, and age. The records of 37 patients having sustained 43 open fractures or mangled upper extremity injuries, seen and treated at the University of New Mexico's Regional Trauma Center between April 1987 and September 1990, have been reviewed. All nine extremity injuries with a MESS of greater than or equal to seven were amputated, and 34 of 34 with a MESS of less than seven were salvaged. Nine Grade IIIC and six mangled extremities were identified in our study. Five of these Grade IIIC and four of the mangled extremities with a MESS of greater than or equal to seven were amputated. All Grade IIIC or mangled extremities with a MESS of less than seven were salvaged. In conclusion, the MESS is an early and accurate predictor for identifying the extremities that may be best treated by amputation.
