Objectives : The purpose of this study is to investigate the relation of Ferguson's angle, Lumbar lordotic angle, Lumbar IVD angle in traffic accident patients. Methods : Total patients were classified into TA(traffic accident) inpatients and non-TA(lumbago) inpatients. We analyzed the characteristics of each group Ferguson's angle, Lumbar lordotic angle, L4-5 IVD angle, L5-S1 IVD angle on X-ray film. Results : 1. Ferguson's angle and Lumbar lordotic angle were smaller than normal range. Non-TA group's angles were smaller than TA group's angles. 2. L4-5 IVD angle of female showed smaller than that of male in TA groups. The older age was, the smaller L4-5 IVD angle was at non-TA groups. 3. L5-S1 IVD angle of female showed smaller than that of male in total groups. The older age was, the smaller L5-S1 IVD angle was at non-TA groups. 4. Ferguson's angle, Lumbar lordotic angle, Lumbar IVD angle were related with direct proportion in total groups. 5. Non-TA groups showed more effective VAS variation than TA groups. Conclusions : Lumbar angles were intimately related with each others. And lumbar angles have an effect on curative value.

Objectives This study was designed to investigate the correlation between the gait analysis indices and Lumbar X-ray indicators. Methods 21 cases of patients who received treatment from October 2013 to February 2017 for abnormal posture were analyzed. Three indicators were measured in the lumbar spine X-ray. These indicators include Ferguson's angle, Lumbar lordotic angle, L4-5 IVD angle. Gait analysis indices were estimated by Treadmill Gait Analysis system. The data were analyzed to find out correlation between the gait analysis indices and Lumbar X-ray indicators. Spearman correlation was used. Results Ferguson's angle and Difference of gait balance of front and rear had a negative linear relationship, but there was no statistical significance. Lumbar lordotic angle and Difference of gait balance of front and rear had a negative linear relationship, but there was no statistical significance. L4-5 IVD angle and Difference of gait balance of right and left had a negative linear relationship, but there was no statistical significance. Conclusions Difference of gait balance of front and rear had strong level of a negative linear relationship with Ferguson's angle and Lumbar lordotic angle.

L-spine 3~4, L-spine 4~5, and L-spine 5~Sacrum 1 intervertebral disc(IVD) angle according to gender, age, body mass index(BMI), lumbar lordosis angle(LLA) were compared and analyzed. The anteriorposterior incidence angle of L-spine 3 ~ 4, L-spine 4 ~ 5 and L-spine 5~Sacrum 1 in body mass index were 5.66, 13.23 and 29.13 degrees in the head direction and L-spine 3 4, L-spine 4 ~ 5, L-spine 5~Sacrum 1 had 6.32 degrees, 16.09 degrees and 35.36 degrees in the head direction. The distortion area ratio comparison was performed with the phantom image using the proposed incidence angle. There was a significant difference in L-spine 4~5 and L-spine 5~Sacrum 1 IVD angle relative to body mass index and LLA(p<0.05), IVD angle and LLA were positively correlated(p<0.05).As a result of evaluating the usefulness of the image by applying the incidence angles of the disc angles according to the phantom angle of deviation to the head direction as 11 degrees for L4 and 26 degrees for L5, the distortion ratio area decreased from 14.90% to 12.11% in L4, And from 15.25% to 13.72% in L5. In anteriorposterior image of the Lumbar spine applying the incidence angle according to the measured disc angle, it is possible to reduce the distortion to purpose L4, L5. And improved the quality and diagnostic information of the target site.
