Prolapsed Intervertebral Disc: A Hyperflexion Injury

ADAMS, M A; HUTTON, W C

Original Article: PDF Only

Sixty-one lumbar intervertebral joints were compressed while wedged to simulate hyperflexion. Twenty-six of the joints failed by posterior disc prolapse. The results show that slightly degenerated discs at lower lumbar levels from subjects aged between 40 and 50 years are most susceptible to prolapse.
