The Association of Sacral Table Angle Measurements With Spondylolytic and Spondylolisthetic Defects at the Lumbosacral Articulation: A Radiographic Analysis

Abstract: Abnormal STA measurement was not seen before the development of spondylolysis in this study population. Decreasing STAs were seen secondarily in patients with L5 spondylolisthetic progression. This finding points to anatomic change and secondary remodeling of the upper sacrum as a result of slippage.

“…The PI was then measured subtended by a line from the bicoxofemoral axis to the middle of the sacral endplate and a line drawn perpendicular to the sacral endplate (Figure 1). STA and SK both correlate strongly with PI in adult cohorts and have been shown to reflect, in some instances, pathologic processes such as spondylolysis so were measured in addition to PI to ascertain how these values change with maturation (McKay et al, 2018;Tallarico et al, 2015;Whitesides Jr. et al, 2005).…”

“…Sacropelvic morphology variations seem to play a role in predisposing indi-viduals to an increased risk of developing spondylolysis through increased biomechanical stress [6,7]. Analyses of sacropelvic parameters between individuals with and without spondylolysis have shown the sacrum's morphometry and its relationship with the pelvis can vary considerably [7][8][9][10][11][12][13].…”

“…Although various sacropelvic parameters have been studied for their association with the development or presence of spondylolysis, few studies have considered multiple parameters simultaneously [6][7][8][9][10][11]14]. Moreover, the main determinants of or risk factors for spondylolysis concerning sacropelvic morphometry need to be identified.…”

“…The sacral table angle (STA) and sacral kyphosis (SK) are widely regarded as fixed anatomic parameters in healthy adults. 7 , 8 , 9 , 10 These parameters could be easily observed on X‐ray images. The STA is relatively widely described in studies of spondylolysis/spondylolisthesis; however, it does not receive enough attention in normal spinopelvic morphology.…”

“…The sacrum is an integrated part of the pelvis and constitutes the undistorted part of the spinal curve, as well as the sacral morphology plays an essential role in sagittal balance. The sacral table angle (STA) and sacral kyphosis (SK) are widely regarded as fixed anatomic parameters in healthy adults 7‐10 . These parameters could be easily observed on X‐ray images.…”
