Answer to the letter to the editor of Zhe Wang et al. concerning "Comparison of cervical, thoracic, and lumbar vertebral bone quality scores for increased utility of bone mineral density screening" by Razzouk J, Ramos O, Ouro-Rodrigues E, et al. [Eur Spine J (2022): doi:10.1007/s00586-022-07484-5]

[摘要] We thank the respondent for their knowledgeable commentary on our study. Certainly, the article by Huang et al. is avaluable contribution to the literature that further advancesour understanding of the still nascent cervical VBQ score[1]. We agree that several factors need to be consideredwhen comparing the two articles given their distinct studydesigns [1, 2]. While Huang et al. compared cervical VBQto DEXA T-scores, our article had a very diferent methodology that did not include evaluating DEXA T-score of thehip but rather evaluated the correlation of the cervical VBQto lumbar and thoracic VBQ. Therefore, a direct comparison between these studies and their results cannot be made.The conclusion of our study was that while thoracic VBQdemonstrated a moderate correlation to lumbar VBQ, cervical VBQ had a low correlation to both thoracic and lumbarVBQ. As the respondent points out, the VBQ in these areasappears to have their own cutof values. The conclusion ofthe referenced study was that cervical VBQ scores were signifcantly correlated with DEXA T-score. Again, both studies had diferent methodologies, results, and conclusions.
