Sarcopenia is associated with increased morbidity and mortality in the trauma patient. The primary objective of this study was to determine the relationship of psoas cross sectional area with hospital mortality in patients with rib fractures over the age of 55 years.We retrospectively reviewed 1223 patients presenting to a Level 1 Trauma Center between 1/1/2002 and 1/31/2019. Psoas cross sectional area was measured using a polygonal tracing tool. Patients were stratified into four quartiles based on sex-specific values.There was increased in-hospital mortality for patients with a lower psoas cross sectional area (10 %, 8%, 6%, and 4%, Q1-Q4 respectively; P=0.021). The logistic regression model determined for every increase in psoas cross sectional area by 1 cm2 the odds of in-hospital mortality decreased by 4%.In-hospital mortality is multifactorial; however, psoas cross sectional area may provide a clue in predicting adverse outcomes after traumatic rib fractures.
