Vertebral deformity, intervertebral disc disorganisation, and change to vertebral bone architecture are morphological features that are associated with low back pain. The purpose of this study was to examine the influence of the morphological disorganisation of the intervertebral disc on vertebral body shape indices and vertebral cancellous bone architecture. Lumbar spines, T12-S1, were collected from 27 cadavers. The motion segments T12-L1, L2-L3 and L4-L5 were selected for the study. There were 8 females aged 35-94 years and 19 males aged 20-90 years. An intervertebral disc grade signifying the severity of disc disorganisation was assigned to each disc using the macroscopic disc grading criteria of Hansson and Roos (Spine, 1981; 6:147-153.). Vertebral shape indices and vertebral body bone histomorphometric analyses were performed on the vertebral bodies. Where appropriate, data were age adjusted and the influence of morphological disc disorganisation on vertebral body deformity and cancellous bone architecture analysed. Increased vertebral body axial area and the ratio of vertebral body axial area to sagittal area were associated with an increase in vertebral deformity and disc disorganisation. This suggests that vertebral deformity that remains clinically silent in the general population is influenced by intervertebral disc disorganisation. Vertebral cancellous bone architecture undergoes change associated with increased disc disorganisation, consistent with increased vertebral deformity. Vertebral bodies adjacent to degenerate discs (Grade 4) showed increased BV/TV and Tb.Th and decreased BS/BV. This shows that disc disorganisation may modulate vertebral cancellous bone architecture such that it protects against age-related bone changes. In addition, vertebral body wedging and concavity are associated with smaller vertebral body size and vertebral body compression is associated with larger vertebral body size and compromised cancellous bone architecture.
