p-Value |
|---|---|---|---|
| Plate position in relation to the physis | 0.049 | ||

| Plate position in relation to the shaft axis of femur/tibia (°) | 2.1 (11.2) | 5.9 (13.5) | 0.31 |
| Plate position in relation to the center of the shaft axis of femur/tibia | 0.39 | ||
| centered | 18 (50.0%) | 10 (71.4%) | |
| posterior | 12 (33.3%) | 2 (14.3%) | |
| anterior | 6 (16.7%) | 2 (14.3%) | |
| Angulation of the two screws (°) | 0.9 (5.3) | 2.8 (6.3) | 0.26 |
| Epiphyseal width/diameter (cm) | 8.2 (1.0) | 8.4 (0.9) | 0.44 |
| Length of the screw (cm) | 2.7 (0.4) | 2.8 (0.4) | 0.60 |
| Ratio screw length/epiphyseal width | 0.34 (0.03) | 0.33 (0.03) | 0.80 |
Parametric data: mean with standard deviation in parenthesis. Positive values of plate position in relation to the shaft axis of femur/tibia mean plate insertion in flexion, negative values mean plate insertion in extension. Positive values of angulation of the screws mean divergent screws, negative values mean convergent screws.
