Assessment of spinal canal shape and intervertebral joint angles in lumbar spine.
Publications concerning the shape of the spinal canal and degenerative changes in the intervertebral joints have not described this issue in full detail to date, especially with regard to the causes of pain syndromes associated with degenerative changes in intervertebral joints. The aim of the study was to assess the shape of the spinal canal and joint surface angles at L3, L4 and L5. ⋯ While the most common pathomechanism underlying degenerative changes is vertebral sinking in the course of disc disease and emerging intervertebral instability, abnormal intervertebral angles can also lead to instability that gives rise to degenerative changes.
