Morphometric analysis of 900 lumbar intervertebral discs: Anterior and posterior height analysis and their ratio

ConclusionsL3 to L5 discs present greater anterior height than posterior and this difference tends to decrease with aging. The L5-S1 disc is that most contributes for lumbar lordosis, followed by L4-L5. Populations with lower average height should have their disc dimensions carefully studied during surgical planning, especially in L3-L4 segment.
