A Biomechanical Study Comparing Helical Blade with Screw Design for Sliding Hip Fixations of Unstable Intertrochanteric Fractures
Figure 4
X-ray after compression testing at SC position in DHS blade and DHS group. In (a) and (b), blade DHS screw reached the top without cutting out. There was no further displacement or rotation. In (c) and (d), conventional DHS screw touched the cortex with migration tract shadow inside femoral head.
