From: The influence of distal screw length on the primary stability of volar plate osteosynthesis—a biomechanical study

Parameter Parameter Group Mean SD Sig.
Load-displacement curves Stiffness [N/mm] A (100 %) 706 103 0.412
B (75 %) 660 124
Elastic limit [N] A (100 %) 177 25 0.496
B (75 %) 167 36
MaxForce [N] A (100 %) 493 139 0.750
B (75 %) 471 149
Zebris Residual tilt [degree] A (100 %) 7.3 0.7 0.755
B (75 %) 7.1 1.3
  1. MaxForce: Maximum force as defined as the force when the slope of the tangent line dropped below 0.95 % of the stiffness; A: 100 % unicortical distal screw length (group A); B: 75 % distal screw length (group B)
  2. SD standard deviation, Sig. adjusted (Bonferroni) level of significance 0.0125
