  1. Group A = infected nonunion; Group B = aseptic nonunion
  2. Data are median values (P25–P75). P-values calculated using Mann–Whitney U test
  3. *P < 0.05 indicates statistical significance
  4. WBC, white blood cell; PC, platelet count; MPV, mean platelet volume; PDW, platelet distribution width CRP; C-reactive protein; ESR, erythrocyte sedimentation rate
