In the Hendrickson et al. study [11], 373 patients with operative fixation were screened by a dietitian, and albumin labs were drawn if they were at medium to high risk; 41% of patients had hypoalbuminemia (<3.5 mg/dL) and the OR for complication risk including nonunion was 1.79 (p = 0.045). This evidence concerns the gene ALB and Hypoalbuminemia.
