Challenges and strategies in the repair of ruptured annulus fibrosus.
Lumbar discectomy is the surgical procedure most frequently performed for patients suffering from low back pain and sciatica. Disc herniation as a consequence of degenerative or traumatic processes is commonly encountered as the underlying cause for the painful condition. While discectomy provides favourable outcome in a majority of cases, there are conditions where unmet requirements exist in ...
متن کاملRiboflavin-Crosslinked Collagen for Annulus Fibrosus Repair In Vivo
Introduction: A weak or damaged annulus fibrosus (AF) often manifests itself in the form of a bulging and herniated intervertebral disc (IVD). This damage is the initial stage in a debilitating cascade, eventually leading to full disc degeneration. Current treatments to impede the progression of early disc degeneration have exhibited limited success [1], with full disc degeneration often prevai...
متن کاملBiphasic scaffold for annulus fibrosus tissue regeneration.
Intervertebral disc (IVD) degeneration is the major cause of lower back pain, while the currently available treatments are symptomatic rather than curative. Tissue engineering is a powerful therapeutic strategy that can restore the normal biomechanical motion of the human spine. The ability of a biphasic elastic scaffold to structurally and elastically simulate the annulus fibrosus (AF) tissue ...
متن کاملAnnulus fibrosus calcification of the mitral valve.
C ALCIUM deposition in diseased heart valves may be demonstrated frequently in necropsy studies, but these deposits are usually overlooked clinicaIIy unless the heart is carefuIly examined roentgenographically. Sosman1 discusses in detail a simple method of demonstrating the presence of calcific deposits within the heart by x-ray. He suggests a small fluoroscopic aperture and a screen of high i...
متن کاملModeling shear behavior of the annulus fibrosus.
Modeling the mechanical properties of the annulus fibrosus has two distinct challenges: the complex loading state experienced in vivo and the anisotropic, nonlinear nature of the tissue. Previous efforts to model the annulus fibrosus have not considered shear data in the analysis, yet the shear response may be critical to understanding tissue behavior and damage. In this study, we compared four...
