LS is the most common cause of spinal surgery in individuals older than 65 years of age. Neurogenic claudication and radiculopathy result from compression of the cauda equina and lumbosacral nerve roots by degenerated spinal elements. Surgical decompression is a well established treatment for patients with refractory, or moderate to severe clinical symptoms. However, the variety of surgical options is vast. New techniques have been developed with the goal of increasing long term functional outcomes. In this article we review lumbar decompression and fusion as treatment options for LS but also present other recent developments. Prospective long term studies are necessary to know which procedures would result in optimal patient outcome.<\/jats:p>","DOI":"10.1590\/s0004-282x2009000300039","type":"journal-article","created":{"date-parts":[[2009,7,16]],"date-time":"2009-07-16T05:07:55Z","timestamp":1247720875000},"page":"553-558","source":"Crossref","is-referenced-by-count":31,"title":["Degenerative
