...It is well known that degenerative change of disk is associated with increased endplate BMD.20,21 We assumed that increased BMD due to disk degeneration of PLIF site might be concerned with relatively low correlation coefficient....

...The average of BMD of cranial and caudal vertebrae at fusion level was assumed as fusion level BMD. Fusion segments were divided to normal BMD segments, osteoporotic segments ( 3.0 Tr 2.5), and severe osteoporotic segments (Tr 3.0)....

...In this mentioned study, the methods of BMD measurement was not explained precisely and their postoperative disk space distraction compared with preoperative value was average 3.2mm, which was larger than other studies.24 It was reported that disk space overdistraction could result in cage subsidence.25 We could explain that this disagreement with our study resulted from the reason that BMD measurement was not conducted in PLIF site and disk space overdistraction impacted on cage subsidence more than BMD....
