Fig. 4From: Effect of oblique headless compression screw fixation for metacarpal shaft fracture: a biomechanical in vitro studyBox plot showing the fracture forces of the four fixation types. Post hoc pairwise comparisons were conducted using the exact Wilcoxon rank sum test with Bonferroni adjustment; same letters indicate that medians were not significantly different at the 0.00833 (0.05/6) level. LP: locked plate with five locked bicortical screws; RP: regular plate with five bicortical screws; K: two K wires; HC: headless compression screwBack to article page
