摘要
目的分析年龄因素下中老年人脊柱-骨盆参数与腰椎旁肌退变的相关性。方法将194例中老年体检者按照年龄段不同分为A组(40~49岁,59例)、B组(50~59岁,77例)及C组(60~69岁,58例)。比较3组脊柱-骨盆参数及腰椎旁肌退变程度指标,分析3组脊柱-骨盆参数与L_(3~4)、L_(4~5)、L_(5)~S_(1)节段腰椎旁肌横截面积(CSA)/椎体CSA的相关性。结果(1)骨盆倾斜角(PT)、骶骨倾斜角(SS)、腰椎前凸角(LL)、骨盆入射角(PI)、PI与LL的差值(PI-LL)3组比较差异均无统计学意义(P>0.05)。(2)各腰椎节段腰椎旁肌CSA/椎体CSA:随A、B、C组均呈逐步下降趋势(P<0.05);3组组内不同腰椎节段腰椎旁肌CSA/椎体CSA:随L_(3~4)、L_(4~5)、L_(5)~S_(1)均呈逐步下降趋势(P<0.05)。(3)3组PT、SS、LL、PI与各腰椎节段腰椎旁肌CSA/椎体CSA的相关性:PT均无相关(P>0.05),SS、LL、PI大体呈正相关(P<0.01)。(4)PI-LL与各腰椎节段腰椎旁肌CSA/椎体CSA的相关性:A组均无相关(P>0.05);B组L_(3~4)、L_(4~5)均无相关(P>0.05)、L5~S1呈弱负相关(P<0.05);C组L_(3~4)、L_(4~5)均呈中等强度负相关(P<0.05)、L_(5)~S_(1)呈弱负相关(P<0.05)。结论中老年人随年龄增加,腰椎旁肌退变程度逐渐加重,甚至可引起腰椎退行性改变。腰椎旁肌的退变随年龄增长与脊柱-骨盆参数间存在一定的相关性,且此种相关性在60岁以上老年人中表现更为明显,提示老年人腰椎旁肌的退变与腰椎退行性改变受年龄因素影响。
Objective To analyze the correlation between spine-pelvis parameters and lumbar paraspinal muscle degeneration in the middle-aged and elderly.Methods The 194 physical examinees were divided into group A(40~49 years old,59 cases),group B(50~59 years old,77 cases)and group C(60~70 years old,58 cases).The spine-pelvis parameters and the indicators of lumbar paraspinal muscle degeneration degree of the three groups were compared.The correlation between spine-pelvis parameters and the lumbar paraspinal muscle cross-sectional area(CSA)/vertebral CSA at L_(3~4),L_(4~5)and L_(5)~S_(1)segments among the 3 groups was analyzed.Results①There were no statistical differences in the pelvic tilt(PT),sacral tilt(SS),lumbar lordosis(LL),pelvic incidence(PI)and the difference value of PI and LL(PI-LL)among three groups(P>0.05).②CSA of lumbar paraspinal muscles/vertebral CSA of each lumbar segment:which was decreased gradually with the age increasing of group A,B and C(P<0.05);CSA of lumbar paravertebral muscles/vertebral CSA at different lumbar segments in the three groups:with L_(3~4),L_(4~5)and L_(5)~S_(1),the data was vertebrae decreased gradually(P<0.05).③The correlation of PT,SS,LL,PI of three groups and CSA of lumbar paraspinal muscles/vertebral CSA of each lumbar segment:there was no relation(P>0.05);SS,LL,PI were positively correlated with CSA of lumbar paravertebral muscle and CSA of vertebral body(P<0.01);④The correlation between PI-LL and CSA of lumbar paravertebral muscles at each lumbar segment:there was no correlation in group A(P>0.05);In group B,there was no correlation between PI-LL and L_(3~4),L_(4~5)lumbar paravertebral muscle CSA/vertebral body CSA(P>0.05),there was a weak negative correlation with L_(5)~S_(1)lumbar paravertebral muscle CSA/vertebral body CSA(P<0.05);In group C,PI-LL was moderately correlated with L_(3~4)and L_(4~5)lumbar paravertebral muscle CSA/vertebral body CSA(P<0.05),and weakly correlated with L_(5)~S_(1)lumbar paravertebral muscle CSA/vertebral body CSA(P<0.05).Conclusions With the age increase of the middle-aged and elderly,the degree of degeneration of lumbar paravertebral muscles gradually increases,and may even cause degenerative changes of the lumbar spine.There is a certain correlation between the degeneration of lumbar paravertebral muscles and the parameters of spine-pelvis with age increasing,and this correlation is more obvious in the elderly over 60 years old,it suggest that the degeneration of lumbar paravertebral muscles and lumbar degenerative changes in the elderly are affected by age factors.
