In 2022, Soliman et al. [
[1]
] published an interesting retrospective study regarding the relationship between poor
bone quality, measured by the vertebral bone quality (VBQ) score using magnetic resonance
imaging (MRI), and the risk of cage subsidence in transforaminal lumbar interbody
fusion (TLIF). The study is intriguing and well-structured, demonstrating how the
VBQ score can independently predict postoperative cage subsidence in patients undergoing
TLIF surgery with a simple and well-quantifiable tool. However, we realized that some
variables in the study's conceptualization need to be considered in view of the limitations
given by a retrospective collection with many missing data (importantly preoperative
laboratory values such as parathyroid hormone and vitamin D 25(OH)D). We would like
to know the views of the authors.To read this article in full you will need to make a payment
