    Introduction: The purpose of this study was to investigate sagittal spinopelvic parameters and the degree of disc degeneration in young adults.

    Methods: From 2009 to 2012, a total of 278 young adult male patients who ranged in age from 18 to 24 years (20.87 ± 1.68) were included in this study. Pelvic incidence (PI), sacral slope (SS) and pelvic tilt (PT), Lumbar lordosis (LL), sacral inclination (SI), lumbosacral angle (LSA), and sacral table angle (STA) were measured. Patients were divided into two groups according to their Pfirrmann grade. The no disc degeneration group (n=100) included those who had no disc degeneration (Pfirrmann grade I), and the disc degeneration group (n=178) comprised the patients who showed disc degeneration (Pfirrmann grade II to V).

    Results: LSA and STA were lower in the disc degeneration group than in the no disc degeneration group. The mean LSA values were 116.80° ± 6.52 in the no disc degeneration group and 113.96° ± 7.05 in the disc degeneration group (p < 0.001). The mean STA values were 97.41° ± 6.06 in the no disc degeneration group and 95.38° ± 6.12 in the control group (p = 0.008).

    Conclusions: In the present study, we found that patients with disc degeneration showed lower LSA and lower STA than patients without disc degeneration. This means that the patients with disc degeneration had more severe lumbosacral and sacral kyphosis, and vertical sacrum. We suggest that lumbosacral kyphosis and sacral kyphosis are risk factors for disc degeneration in young adults, and STA and LSA should be considered to prevent further disc degeneration. Also, our study demonstrated that lumbosacral structure with a more vertical orientation causes a tendency to develop disc degeneration and herniation. Therefore, exercises to improve a vertical sacrum, such as extension traction treatment, would be helpful in preventing further disc degenerations.

Also, our study demonstrated that lumbosacral structure with a more vertical orientation causes a tendency to develop disc degeneration and herniation. Therefore, exercises to improve a vertical sacrum, such as extension traction treatment, would be helpful in preventing further disc degenerations (Fig. 2).
