BACKGROUND: In the lumbar spinal column, an annular disruption may be sealed after
annulotomy to prevent further prolapse and instability. We investigated the biomechanical …

BACKGROUND: The adverse effects of annulotomy during lumbar discectomy have been
increasingly recognized, and methods are developing to repair the annular defect …

Study Design. Mechanically induced annular disruption of lumbar intervertebral discs
followed by microstructural investigation. Objective. To investigate the role that elevated …

Background Integrity of intervertebral disks may influence, and be influenced by, the
maintenance of hydrostatic pressures inside the nucleus pulposus. Disk degeneration …

Previous studies postulated that an axial compression of lumbar intervertebral discs causes
a complex strain pattern on the annulus. This pattern is not fully understood, since most …

The technique used to incise the disc during discectomy may play a role in the subsequent
healing and change in biomechanical stiffness of the disc. Several techniques of lumbar disc …

Several techniques of lumbar disk annulotomy have been described in clinical reports, but
have not addressed the influence of annulotomy type on motion-segment stability. The …

The objective of this study was to analyze the effects of annulus fibrosus incision and
foraminoplasty on lumbar biomechanics during posterior lateral approach translaminar …

Vertebral endplate fracture is generally accepted to occur as a result of excessive, typically
rapid, pressure developed within the intervertebral disc. Clinical evidence of disc disorders …

The inter-lamellar connectivity of the annulus fibrosus in the intervertebral disc has been
shown to affect the prediction of the overall disc behaviour in computational models. Using a …
