摘要:
目的:探讨骨盆入射角(PI )与腰椎融合术后相邻节段退变的关系,并提出具有临床指导意义的预测腰椎融合术后相邻节段退变的方法。方法:选取2010年1月至2012年12月间骨科因腰椎管狭窄症行单节段后路椎管减压+椎弓根螺钉固定+植骨融合手术的患者,共计50例。测量并记录术前骨盆入射角,根据PI值将患者分为两组,A组PI≥45°,B组PI<45°.分别测量术前及术后两年的腰椎前凸角(LLA),融合节段头端相邻节段椎间隙高度(IH)、伸屈位活动度(ROM )、中立位椎体移位距离(SD)。结果:术前两组患者的IH,ROM,SD值均无统计学差异(P>0.05); 术后2年,两组患者LLA,IH变化值无显著差异(P>0.05),而SD,ROM有显著差异(P<0.05)。结论:PI值是骨盆对腰椎生理变化代偿能力的指标,PI值越大则代偿能力越强; PI值较小的患者,更容易出现腰椎融合术后相邻节段退变,术后功能更差。
Abstract:
Objective:To investigate the relationship between pelvic incidence(PI)and adjacent segment degeneration after lumbar fusion,and to propose a method for predicting the adjacent segment degeneration after lumbar fusion.Methods:From January 2012 to December 2010,a total of 50 cases were selected,which underwent single segment posterior decompression,pedicle screw fixation and bone graft fusion surgery for lumbar spinal stenosis.After the measurement of preoperative pelvic incidence(PI),the patients were divided into A group(PI≥45°)and B group(PI<45°).Before and two years after operation,the lumbar lordosis,intervertebral height,range of motion and slip distance were measured.Results:There was no significant difference in SD,ROM and IH values between the two groups(P>0.05).There was no significant difference in the change of LL and IH between the two groups after 2 years(P>0.05),while SD and ROM were significantly different(P<0.05).Conclusion:PI value is the index of the ability of pelvis to compensate the physiological changes of lumbar spine.The greater the PI value,the stronger the compensatory ability.Patients with smaller PI values were more likely to have adjacent segment degeneration after lumbar fusion.
