摘要
目的 :应用生物力学的方法分析骶骨倾斜移位与L_5S_1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L_5S_1DH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L_5S_1DH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L_5S_1DH中L_5S_1椎间隙与腰骶角无相关性(P>0.05)。结论:骶骨倾斜移位与L_5S_1椎间盘退变之间密切相关,为临床治疗慢性顽固性L_5S_1椎间盘突出症提供了一新的认识理念与治疗途径。
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 L5S1 DH 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＋0.38 x,P〈0.01）;Male patients with L4-5DH were more obvious（R=0.55,P〈0.05,y=5.80＋0.43 x,P〈0.01）;Female patients with L5S1 DH were particularly evident（R=0.74,P〈0.01,y=0.91x-5.30,P〈0.01）. The lumbosacral angle and L4-5intervertebral 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 L5S1 DH. 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 L5S1 DH.
