The pathophysiological process behind<unk> 's RILP nerve damage has been discussed since the 1960s and is still without a precise definition. Consensus does exist on a progression of RILP symptoms, with a stepping (a time delay) between two periods of<unk>  onset, the first from<unk>  injury and the later from fibrosis. Proposed mechanisms of the early nerve damage include microvascular damage (ischemia) supplying the myelin,<unk>  damage of the myelin, and oxygen free radical cell damage. The delayed nerve damage is attributed to compression neuropathy and a late fibro-atrophic ischemia from retractile fibrosis.
