ISSLS Prize Winner: Microstructure and Mechanical Disruption of the Lumbar Disc Annulus

Abstract

This study demonstrates a far greater complexity to the interlamellar architecture of the disc annulus than has previously been recognized. Our findings are clearly relevant to disc biomechanics. Significant degrading of the translamellar bridging network may result in annular weakening leading potentially to disc failure. Most importantly this work opens the way to a much clearer understanding of the microanatomy of the disc wall.
