Table 2 Comparison Results ofRadiographic Measurements between SER and PER Groups

From: Morphological characteristics of the posterior malleolar fragment according to ankle fracture patterns: a computed tomography-based study

  SER (n = 76) PER (n = 31) P-value
Alphaangle 13.1 (8.9 17.4) 13.6 (8.6 18.7) 0.7869
FLR 24.7 (21.0 28.4) 28.3 (24.0 32.7) 0.0249
FAR 12.2 (8.8 15.7) 15.0 (10.9 19.1) 0.0762
Fagittal angle 21.2 (17.7 24.7) 17.5 (13.4 21.7) 0.0173
Fragment height 17.6 (14.4 20.9) 21.6 (17.7 25.5) 0.0062
  1. Values are mean (95% CI) adjusted by age and Jan Bartonicek classification
  2. SER supination-external rotation, PER pronation-external rotation, FLR fragment length ratio, FAR fragment area ratio
  3. P-values are calculated by analysis of covariance adjusted for age and Jan Bartonicek classification
