FERRACUTTI, R.O; CZERNIECKI, A; PALOTO, J  e  MOLINARI, N. Analysis of the Causes of Intervertebral Disk Hernia. Inf. tecnol. [online]. 2004, vol.15, n.1, pp.43-48. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642004000100007.

The objective of this work is to prove the hypothesis that intervertebral disk hernia is produced by fatigue of the material and not by simple compression. Pieces of fresh ovine lumbar columns were submitted to compression tests. The experiments showed that when the samples are submitted to charges of single application, fail in the bone and when are submitted to fatigue tests, they fail in the intervertebral disk. It is concluded that the intervertebral disk hernia is produced by repetitive charges as axial compression and that a single traumatism does not generate a disk hernia.

Palavras-chave : disk hernia; intervertebral disk; fatigue by compression; axial compression.
