Letter to the Editor concerning “Bacteria: back pain, leg pain and Modic sign—a surgical multicentre comparative study” by Fritzell P, et al. (Eur Spine J [2019]; doi:10.1007/s00586-019-06164-1)

[摘要] We read with great interest the recent article on bacterial presence in intervertebral disc samples by Fritzell et al. The authors have performed a multicenter analysis exploring the correlation of bacterial presence/growth in discs and have investigated whether Modic changes were associated. We have specifc concerns on the validity of the methodology used and the arguments put forth by the authors in the manuscript. We also present our viewpoints on this topic, according to the recent literature.
