目的：应用生物力学的方法分析骶骨倾斜移位与 L5S1椎间盘退变之间的相关性。
方法：2011年7月至2013年7月，选取81例腰椎间盘突出症（LDH）合并骶髂关节紊乱的患者，其中男45例，女36例；年龄18～65岁，平均（45.39±1.30）岁；病程1～60个月，平均（12.64±2.19）个月。拍摄患者腰椎侧位X线片81张，测量腰椎曲度，L4-L5或L5-S1椎间隙的距离及腰骶角，然后进行相关性分析。
结果：在L5S1DH中女性患者的腰椎曲度明显大于男性患者[（22.18±8.62）° vs（16.17±4.97）°，P<0.05]. LDH中腰椎曲度与腰骶角呈正相关性（R=0.48，P<0.01，y=7.25+0.38x，P<0.01）；男性患者在L4，5DH中较明显（R=0.55，P<0.05，y=5.80+0.43x，P<0.01）；女性患者在L5S1DH中尤为明显（R=0.74，P<0.01，y=0.91x-5.30，P<0.01）.L4，5DH中腰骶角与L4，5椎间隙之间呈正相关性（R=0.27，P<0.05）；而在L5S1DH中L5S1椎间隙与腰骶角无相关性（P>0.05）.
结论：骶骨倾斜移位与L5S1椎间盘退变之间密切相关，为临床治疗慢性顽固性L5S1椎间盘突出症提供了一新的认识理念与治疗途径。 |

Abstract:
Objective: To biomechanical analysis of the correlation between sacral tilt displacement and L5-S1 disc degeneration.
Methods: 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.
Results: The lumbar curvature of female patients with L5S1DH were significantly larger than male patients [(22.18±8.62)° vs(16.17±4.97)°，P<0.05]. Lumbar curvature and lumbosacral angle showed a positive correlation in LDH(R=0.48,P<0.01,y=7.25+0.38x,P<0.01);Male patients with L4-5DH were more obvious(R=0.55,P<0.05,y=5.80+0.43x,P<0.01);Female patients with L5S1DH were particularly evident(R=0.74,P<0.01,y=0.91x-5.30,P<0.01). The lumbosacral angle and L4-5 intervertebral gap was a positive correlation in L4-5DH(R=0.27,P<0.05); While L5-S1 intervertebral gap and lumbosacral angle were not correlated(P>0.05)in L5S1DH.
Conclusion: The sacral tilt displacement and L5-S1 disc degeneration were closely related to provide a new understanding philosophy and therapeutic approach for clinical treatment of intractable lumbar L5S1DH. |
