【摘要】:目的探討下位腰椎間盤突出與髂腰韌帶力學強度的關系。方法收入我院脊柱外科2012年至2014年收治的130例下位腰椎間盤突出癥患者其中L4/5節(jié)段73例,L5/S1節(jié)段57例。正常組為我科沒有腰痛病史的醫(yī)護以及進修醫(yī)師45例。在腰椎正位片上測量并計算出各病例第5腰椎橫突的長度,寬度,椎弓根間的距離,橫突寬度與椎弓根內間距比值(RT值),橫突長度與椎弓根內間距比值(RL值),對所得數值進行統(tǒng)計學分析。結果正常組、椎間盤突出組在年齡、性別差異無顯著性意義。腰椎間盤突出癥組的椎弓根間距離為29.6mm顯著小于正常組30.8mm(P=0.0032),橫突長度的左右差為1.84正常組為1.36,左右比值椎間盤突出組1.054正常組為1.040,表示椎間盤突出組比正常組有增大傾向。同時,椎間盤突出組RL左右差為6.25,正常組為4.51差異具有統(tǒng)計學意義(P=0.0408)。按照腰椎間盤突出節(jié)段分為L4/5和L5/S1組。測量L5橫突寬度,L4/5組:19.9mm,L5/S1組:18.3mm由此計算的RT值L4/5:66.7,L5/S1:62.9,L4/5組比L5/S1組的L5橫突寬度以及RT均有顯著統(tǒng)計學差異。結論髂腰韌帶力學強度與椎間盤突出相關,并影響突出節(jié)段。
[Abstract]:Objective to investigate the relationship between lumbar disc herniation and the mechanical strength of iliolumbar ligament. Methods 130 patients with L4 / 5 segment L5 / S1 segment were admitted to our hospital from 2012 to 2014. The normal group consisted of 45 medical and advanced physicians who had no history of low back pain. The length of the transverse process of the fifth lumbar vertebrae was measured and calculated on the lumbar vertebrae positive radiographs. The width, the distance between pedicles, the ratio of transverse process width to pedicle distance, the ratio of transverse process length to pedicle distance, and the ratio of transverse process length to pedicle distance were analyzed statistically. Results in the normal group, the intervertebral disc herniation group was in age. The distance between pedicle of lumbar intervertebral disc herniation group (29.6mm) was significantly lower than that of normal group (30.8 mm), the left and right difference of transverse process length was 1.36 in normal group, and the ratio of intervertebral disc herniation was 1.040 in 1.054 normal group. The disc herniation group had a tendency to increase compared with the normal group. At the same time, The difference between left and right RL was 6.25 in disc herniation group and 4.51 in normal group. According to the segment of lumbar disc herniation, L4 / 5 and L5/S1 groups were divided into L4 / 5 and L5/S1 groups. The RT value of L4 / 5: 66.7% L5 / S1: 62.9% L4 / 5 was calculated by measuring the width of L4 / 5 transverse process in L4 / 5 group as compared with that of L5 / 5 group in L5/S1 group. Conclusion the mechanical strength of iliolumbar ligament is associated with disc herniation. And influence protruding segment.
