Table 1 Stiffness (ST), angular displacement (AD) and interfragmentary displacement (ID) in the three study groups (GR) for volar (V) and double (D) plating (PL) under neutral (N) loading condition, flexion (F) and extension (E), in terms of mean and standard deviation. P-value (P) indicates statistical differences between volar and double plating for the respective outcome. Bold values indicate significant differences
