[Destabilization after surgical treatment of narrow lumbar canal: when should arthrodesis be performed?].
Post-operative spine displacement occurs by excessive or aggravated vertebral sliding. Sex and age, anatomics factors (pre-operative displacement, intersomatic discs quality, hyperlordosis) and operative factors (extensive laminectomy, artherectomy) are predisposing factors. The risk of post-operative vertebral displacement is calculated by a fine pre and per-operative analysis of these pre-disposing factors: Tolerance to post-operative spinal displacement cannot be foreseen and surgical recovery may be difficult whenever.
