STUDY DESIGN: Retrospective study for @entity614 due to @entity850 with @entity28523 ( @entity28523 ) at the L5/S disc. OBJECTIVE: To investigate the influence of the L5/S @entity28523 on @entity614 , due to L5/S @entity850 . SUMMARY OF BACKGROUND DATA: Foraminal @entity850 has often been detected via images. However, although this condition is well known, it is occasionally overlooked during diagnosis, because @entity2850 is not always visible on stationary images. METHODS: @entity1 who underwent lumbar spine surgery were examined to determine the presence of @entity850 (n=194). The presence of @entity28523 and the range of motion of the L5/S disc were assessed on radiography with the lumbar spine in the extended and flexed positions. The shapes of the L5/S foramina were confirmed using sagittal magnetic resonance imaging. @entity1 who showed @entity28523 were divided into 2 groups: @entity1 with (group A) and without (group B) symptomatic @entity850 . The relationship between the @entity28523 and symptomatic @entity850 was examined. RESULTS: In total, 35 cases of @entity28523 at the L5/S disc were noted on lateral radiography. @entity614 due to L5/S @entity850 was identified in 14 of these 35 cases. The ranges of L5/S angles were 10    4   and 5    3   in groups A and B, respectively, and these values were significantly different (P < 0.01). 11 (48%) of 23L5/S foramina that showed @entity28523 of the L5/S disc and were completely occupied by a disc below the caudal edge of the vertebra had symptomatic @entity850 . CONCLUSION: Our results indicated that @entity28523 , which showed a large range of motion angle between flexion and extension, triggered symptoms of @entity850 at the L5/S disc. The dynamic motion of the @entity28523 should thus be considered for the diagnosis of L5/S @entity850 . LEVEL OF EVIDENCE: 3.
