Characteristics of intradiscal vacuum phenomena by distribution. a Number of vacuum phenomenon (VP)-positive discs in males and females. b Number of vacuum phenomena (VPs) by age group in VPs distribution. The counts of VP-positive discs are written in the graph. Percentages in parentheses indicate the proportion of VP-positive discs of each rupture shape compared with the total number of VP-positive discs by gender (a) and by age group (b). VP: vacuum phenomenon; VP-: non-ruptured group; Nucleus pulposus: N; anterior annulus fibrosus: A; and posterior annulus fibrosus: P
