Fig. 5From: A finite element analysis and cyclic load experiment on an additional transcortical-type hole formed around the proximal femoral nail system’s distal locking screw A Failure is defined as construct breakage around the distal locking screw, whichever occurred first (B) Log-rank test results, which defined cycle value as time and failure as end point, show a significant difference between the NHO group and AH and PH groups (P < 0.001). C Between AH group and PH group, neither Fisher’s exact test (P = 1) nor the Log-rank test (P = 0.072) showed a significant difference Back to article page
