Table 1 Construct stiffness data in extension loading direction for different K-wire configurations or external fixator

From: Biomechanical analysis between Orthofix® external fixator and different K-wire configurations for pediatric supracondylar humerus fractures

Extension loading Magnitudes (N/mm) ANOVA (P) Comparison (P)
Mean ± SD (I) (II) (III) (IV) (V)
Two crossed K-wires (I) 6.2 ± 1.0 0.000 0.048 0.605 0.028 0.013
Two lateral K-wires (II) 5.1 ± 1.3 0.038 0.000 0.000
Three lateral K-wires (III) 6.5 ± 1.5 0.140 0.066
Three crossed K-wires (IV) 7.5 ± 1.4 0.572
External fixator (V) 7.9 ± 1.7
  1. Italicized values are significantly different between two groups (P < 0.05)
  2. The values are given as mean ± standard deviation
