Objective: Although theoretical possibility that facet joint could be an important cause of low back pain, there is few clinic basis about low back pain which is caused by derangement of facet joint. We investigated parallelism of two lines, which connects the angle of inclination and epiphysis of each lumbar segment, and found out the stability of each segment.
Methods: We examined the Fergnson’s angle and I.V.D Angle(L4-5, L5-S1) of lumbago patients by simple X-ray film(L-S spine lateral view). The normal Fergnson’s angle was arranged 34 degrees and was classified by every 5 degrees, and the normal I.V.D Angle(L4-5, L5-S1) was arranged 15 degrees and was classified by every 5 degrees.
Results:
1. In the distribution of Fergnson’s angle, 31-35 degrees were 25 cases(32.1%), 26∼30 degrees were 15 cases(19.2%), 36∼40 degrees were 13 cases(16.7%), 21∼25 degrees were 7 cases(9.0%), 15∼20 degrees were 6 cases(7.7%), 46∼50 degrees were 5cases(6.4%), 41∼45 degrees were 4 cases(5.1%), 51∼55 degrees were 2 cases(2.6%), below 10 degrees was 1 case in the sequence.
2. In the distribution of I.V.D angle of L4-5, 6∼10 degrees and 11∼15 degrees were 33 cases(42.3%) each, below 5 degrees were 8 cases(10.2%), 16∼20 degrees were 4 cases(5.1%) in the sequence.
3. In the distribution of I.V.D angle of L5-S1, 11∼15 degrees were 28 cases(35.9%), 16∼20 degrees were 27 cases(34.6%), 6∼10 degrees were 9 cases(11.5%), 21∼25 degrees were 8 cases(10.2%), below 5 degrees were 4 cases(5.1%), 26∼30 degrees were 2 cases(2.6%) in the sequence. Below 15 degrees which is relatively stable angle, were 32 cases(41.0%), and the angle which disturbs the stability of facet joints were 46 cases(58.9%) in the patients.
Conclusions: Many lumbago patients had the big angle which disturbs the stability of facet joints and subluxations of I.V.D angle in L5-S1.
