Open discectomy performed in patients with small, contained herniations may result in poor outcomes. The various techniques of percutaneous disc decompression (<jats:styled-content style=\"fixed-case\">PDD<\/jats:styled-content>) have been developed to address this population.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A literature search was conducted on articles, which address <jats:styled-content style=\"fixed-case\">PDD<\/jats:styled-content> for lumbar radicular pain. Published techniques include chymopapain chemonucleolysis, percutaneous laser disc decompression (<jats:styled-content style=\"fixed-case\">PLDD<\/jats:styled-content>), automated percutaneous lumbar discectomy (<jats:styled-content style=\"fixed-case\">APLD<\/jats:styled-content>), Dekompressor, nucleoplasty, and targeted disc decompression (<jats:styled-content style=\"fixed-case\">TDD<\/jats:styled-content>). In addition, the rationale of provocative discography, selective nerve root injections, and intra\u2010op discograms before performing <jats:styled-content style=\"fixed-case\">PDD<\/jats:styled-content> is discussed in detail.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Dekompressor and nucleoplasty have the best level of evidence with a score of 2B+. The chymopapain chemonucleolysis has the most publications, but it is also accompanied by the most significant adverse complications and so it is scored as a 2B+\/\u2212. The other techniques are supported mainly by observational studies and thus their scores range between 0 and 2B+\/\u2212. There is no supporting evidence for provocative discography in patients with lumbar radicular pain. The evidence for a positive selective nerve root injection as an inclusion criteria or the need for an intra\u2010op discogram shows mixed results.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Nucleoplasty and Dekompressor have a weak positive recommendation for the treatment of patients with lumbar radicular pain.
