| Objective: To measure the anatomical morphology parameters of degenerative lumbar spondylolisthesis(DLS) patients and the control group,and compare the measurement value, the value of different age groups and different gender groups about the patients, discuss the relationship between the anatomical morphology of the lumbar and degenerative lumbar spondylolisthesis.Methods: Include 150 degenerative lumbar spondylolisthesis patients who have the lateral lumbar spine examination and CT examination in our hospital from February 2015 to February 2016 as the patient group, 38 males, 112 females.(54.9±13.57) years old. According to the age, patients will be divided into 4 sub groups.In corresponding period, select 100 patients of lumbar spondylolisthesis, no obvious lumbar degeneration who have lateral lumbar spine examination and lumbar CT examination in our hospital randomly as the control group, 27 males, 73 females,(47 ±13.01) years old.Measure the lumbosacral joint angle(Grogkopff) and the lumbar lordosis angle in the lumbar lateral radiographs, observe whether there is lumbosacral transitional vertebra. Measure the L4-L5 angle of zygapophysial joints in the CT image, calculate the difference of bilateral facet joint angle, and the asymmetry rate of bilateral facet joint.Compare the measurement parameters of lumbosacral joint angle and lumbar lordosis angle, angle of zygapophysial joints, bilateral facet joint angle difference, bilateral facet joint asymmetry ratio, lumbosacral remove vertebral occurred rate between the patient group and control group. For the patient group, compare the measurement value of lumbosacral angle and lumbar lordosis angle, facet joint angle with subgroups of different age and different gender. Data will be processed using IBM SPSS 13 software. Statistics will be expressed with sample mean± standard deviation(±S).The difference is statistically significant when the definition of test level ?= 0.05 and P<0.05, the difference is obvious when P<0.01.Results: No statistically significant difference between patient group and control group in ages(t=2.01, P=0.91). No statistically significant difference between genders(?2=0.06, P=0.81).Angle of the lumbar and sacral joint: the patient group was135.41±4.55, the control group was 143.52±7.77, the angle of the lumbar and sacral joint of the patient group was less than the control group(t=3.769, P=0.001).Lumbar lordosis angle: the patient group was 39.98±9.53, the control group was 47.64±10.64. The lumbar lordosis angle of the patient group was less than the control group(t=-2.522, P=0.021).Articular facet joint angle: the patient group was 36.53±11.00, the control group was 49.57±7.17, the articular facet joint angle of the patient group was less than the control group(t=4.615, P=0.033).Difference of bilateral facet: the patient group was 5.28±497,the control group was 7.37± 4.93, no statistically significant difference(t=-1.428, P=0.335).Bilateral facet joint asymmetry ratio: 33 cases in the patient group, 23 cases in the control group, no statistically significant difference(?2=0.035, P=1.000). Lumbosacral transitional vertebra: 41 cases in the patient group, the incidence rate was 27.3%; 3 cases in the control group, the incidence rate was 3%. Transvertebra incidence rates was significantly higher than the control group(?2=24.497, P=0.000).There were no significant differences in the lumbar and sacral joint angles between the different age subgroups(P>0.05) in the patient group. The facet joint angle, lumbar lordosis angle between the age subgroups hadstatistically significant difference(P<0.05). Among them, the facet joint angle and lumbar lordosis angle of the 51 ~ 60 years old was obviously different from the 31 ~ 40, 41 ~ 50 years old, the articular facet angle and the lumbar Di joint angle of the 51 to 60 years old was smaller(P<0.01); the facet joint angle and lumbar lordosis angle of the patients above the 60 years old was also obviously different from the 31 ~ 40, 41 ~ 50 years old,the articular facet angle and the lumbar Di joint angle of the patients above 60 years old was smaller(P<0.01). The rest of the subgroups had no statistical difference between the each group(P>0.05).In the patient group, there were statistical difference in the angle of the lumbar Di(t=1.80, P=0.009) between the male and female, the angle of the female was smaller than that of the male. The angle of zygapophysial joints between the male and the female had nostatistically significant difference(t=1.00, P=0.500); So was the lumbar lordosis(t=0.96, P=0.512).Conclusions: The facet joint angle, lumbosacral angle and lumbar lordosis angle, lumbosacral shift vertebral incidence ratio of the patient group and the control group have statistically significant difference; the joint facet angle difference, bilateral hip articular process of asymmetric rate have no statistically significant difference. The articular facet angle,the lumbar sacral joint angle and the lumbar lordosis angle of the patient group is smaller, and the lumbosacral shift vertebral occurres at a higher rate. The facet joint angle and lumbar lordosis angle of the different ages in the patient group have statistically significant difference, the lumbar lordosis angle and the joint angles of zygapophysial joints of the elders is smaller. The angle of the lumbar and sacral joint of the female was significantly lower than that of the male in the patient group. Small Joint angles of zygapophysial joints, small waist lumbosacral angle and small lumbar lordosis angle, lumbosacral shift vertebral may be the risk factors for degenerative lumbar spondylolisthesis. |
