The purpose of this study was to investigate whether transitional vertebrae contribute to the development of sacroiliac joint dysfunction. The prevalence of transitional vertebrae in patients with lumbar pain was determined during this process, and the prevalence of sacroiliac dysfunction was compared between patients with low back pain and healthy volunteers. ⋯ Sacroiliac joint dysfunction must be considered when investigating the etiology of low back pain. Particular sensitivity must be exhibited on this subject in patients with transitional vertebrae.

Comparative Study Observational Study
Uneven intervertebral motion sharing is related to disc degeneration and is greater in patients with chronic, non-specific low back pain: an in vivo, cross-sectional cohort comparison of intervertebral dynamics using quantitative fluoroscopy.
Evidence of intervertebral mechanical markers in chronic, non-specific low back pain (CNSLBP) is lacking. This research used dynamic fluoroscopic studies to compare intervertebral angular motion sharing inequality and variability (MSI and MSV) during continuous lumbar motion in CNSLBP patients and controls. Passive recumbent and active standing protocols were used and the relationships of these variables to age and disc degeneration were assessed. ⋯ Greater inequality and variability of motion sharing was found in patients with CNSLBP than in controls, confirming previous studies and suggesting a biomechanical marker for the disorder at intervertebral level. The relationship between disc degeneration and MSI was augmented in patients, but not in controls during passive motion and similarly for MSV during active motion, suggesting links between in vivo disc mechanics and pain generation.

The Quality of Life Profile for Spine Deformities (QLPSD) is a self-reporting questionnaire designed for studying patients with spinal deformities. ⋯ The G-QLPSD proved to be a highly reliable and valid instrument that can be recommended for clinical use in scoliosis patients.
