- Abstract
- OBJECTIVE: The purpose of this study was to determine reference values for the sagittal plane alignment of the thoracolumbar junction (TLJ) in a young adult Korean population.
METHODS: Thoracolumbar computed tomography (CT) scans of 1000 individuals (age range, 20-39 years; 500 men and 500 women) from Hanyang University Health Care Center were reviewed. All subjects had no spinal pathology or a history of previous spinal surgery. The segmental (each level from T11 to L2) and global (T11-L1 and T11-L2) Cobb angles of the TLJ of the spine were measured in midsagittal CT scans. Moreover, comparisons between the 2 age groups (20s and 30s) and sexes were performed.
RESULTS: The segmental Cobb angles of T11, T12, L1, and L2 were 6.5 degrees +/- 3.9 degrees, 5.5 degrees +/- 4.1 degrees, 2.2 degrees +/- 4.7 degrees, and L3.3 degrees +/- 5.3 degrees, respectively. The global Cobb angles of T11-L1 and T11-L2 were 6.5 degrees +/- 5.2 degrees and 0.5 degrees +/- 6.1 degrees, respectively. There were no differences in the sagittal alignment between the 2 age groups. Women presented less kyphotic and more lordotic alignment in the lumbar spine (L1 and L2) than men; however, the thoracic spine (T11 and T12) alignment was not different between the 2 groups.
CONCLUSIONS: This study provides reference values with a wide physiologic range for the sagittal alignment of the TLJ of the spine in a young adult Korean population.
