To biomechanical analysis of the correlation between sacral tilt displacement and L₅-S₁ disc degeneration. From July 2011 to July 2013, 81 patients with lumbar disc herniation and sacroiliac joint disorder including 45 males and 36 females with an average age of (45.39±1.30) years ranging from 18 to 65 years old were selected. The course of the disease ranged from 1 to 144 months with an average of (12.64±2.19) months. All patients were taken lumbar spine lateral X-ray films, the lumbar curvature angle, L₄-L₅ or L₅-S₁ intervertebral gap distance between points, and the lumbosacral angle was measured and correlated analyzed. The lumbar curvature of female patients with L₅S₁DH were significantly larger than male patients [(22.18±8.62)° vs (16.17±4.97)°, <0.05]. Lumbar curvature and lumbosacral angle showed a positive correlation in LDH ( =0.48, <0.01,y=7.25+0.38x, <0.01); Male patients with L₄-₅DH were more obvious ( =0.55, <0.05, y=5.80+0.43x, <0.01); Female patients with L₅S₁DH were particularly evident( =0.7
