Fig. 6.

Percentage contribution of upper and lower portion of graft to whole fusion segment collapse. In static locking plate, contribution of the upper portion to whole graft shortening was significantly higher than in the lower portion (p=0.00058). In non-locking plate, the collapse rate was not different between the upper and lower portion of fusion segments. ^*p<0.05. LD : lower distance between lower endplate and lower end of plate, UD : upper distance between upper endplate and upper end of plate.
