Original Article



Percutaneous cement discoplasty (PCD) is a minimally invasive surgical procedure, that can provide a segmental stabilizing and indirect decompression effect in case of severely degenerated discs characterized by vacuum phenomenon. The objective of this study was to evaluate the effects of PCD on spinopelvic radiological parameters and their associations with the clinical outcome.


Retrospective analysis of prospectively collected dataset of 28 patients (112 lumbar segments) who underwent single- or multilevel PCD was performed. Spinopelvic, intrasegmental and intersegmental parameters were measured on lumbar X-rays pre-, postoperatively and 6 months after the surgery. Correlations between radiological parameters and clinical outcome data were determined.


Sacral slope significantly increased (p < .001), and pelvic tilt (p < .05) was decreased after the PCD procedure. Segmental and total lordosis (p < .05, p < .05) disc and foraminal height showed significantly increase (p < .001, p < .001) after procedure. Pain and disability (ODI) significantly decreased due to PCD. An association was found between postoperative increase in SS and improvement in ODI (r = 0.39, p < .05). The change in low back pain was correlated with segmental scoliosis correction (p < .001). Moderate correlation was detected between the increase in disc height and ODI (p < .05) as well as leg pain (p < .01).


PCD is an effective minimally invasive technique to treat axial pain and disability related to severe lumbar disc degeneration. Our study shows that an improvement in lumbar alignment and a significant indirect foraminal decompression could be achieved with the procedure. These changes can significantly contribute to the pain relief and increase in the patients’ functional capacity.
