Letter to the Editor concerning “Indirect foraminal decompression and improvement in the lumbar alignment after percutaneous cement discoplasty” by Laszlo Kiss et al. (Eur Spine J; 28(6):1441–1447)

[摘要] We read the article entitled “Indirect foraminal decompression and improvement in the lumbar alignment after percutaneous cement discoplasty” with great interest. The authors evaluate the efects of percutaneous cement discoplasty (PCD) on spinopelvic radiological parameters and their associations with the clinical outcome. This is interesting since it further improved the evaluation system of PCD. We appreciate the tremendous work by the authors. But also we have some concerns regarding the study.
