Injury Severity Score (ISS) is the most widely used method of assessing severity of injury in blunt trauma. It has been recognized that, by only allowing the score to consider the worst injury for each body system, ISS underestimates the problems of multiple musculoskeletal injuries. The New ISS (NISS) allows the three most severe injuries to be scored, irrespective of region affected, and may give better prediction of functional recovery in these patients. ⋯ NISS, a simple modification from ISS, better predicts functional outcomes in survivors of musculoskeletal trauma, and offers an improvement in the assessment of effectiveness of trauma care delivery.
