Das Durchschnittsalter betrug 51,2\u00a0Jahre (30 bis 76). In 23\u00a0F\u00e4llen wurde eine ventrodorsale Operationstechnik verwendet, in 4\u00a0F\u00e4llen ein rein dorsales Vorgehen mit Interposition eines intervertebralen Cages. Das Follow-up betrug 2\u00a0Jahre. Der Oswestry-Score (Oswestry Disability Index [ODI]) verbesserte sich von durchschnittlich pr\u00e4operativ 40,6\u202f% auf 16,6\u202f% postoperativ. Die visuelle Analogskala (VAS) bez\u00fcglich des R\u00fcckenschmerzes verbesserte sich von pr\u00e4operativ 6,7 im Durchschnitt auf 2,1 im 2\u2011Jahres-Follow-up. Im Rahmen dieses Beobachtungszeitraumes wurden 2\u00a0implantatspezifische Komplikationen beobachtet. Ein Facet Wedge musste aufgrund einer Fehlpositionierung mit fr\u00fchzeitiger Lockerung revidiert werden. In einem weiteren Fall kam es zu einem Korrekturverlust bei einer pr\u00e4operativ bestehenden erstgradigen Spondylolisthese mit Revision auf ein dorsales Schrauben-Stab-System.<\/jats:p>\n<\/jats:sec>","DOI":"10.1007\/s00064-020-00659-7","type":"journal-article","created":{"date-parts":[[2020,3,16]],"date-time":"2020-03-16T16:04:06Z","timestamp":1584374646000},"page":"209-218","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Facet Wedge: eine minimalinvasive Technik zur dorsalen segmentalen intraartikul\u00e4ren Fusion","The Facet Wedge: a minimally invasive technique for posterior segmental intra-articular fusion"],"prefix":"10.1007","volume":"32","author":[{"given":"Christoph","family":"Mehren","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Sauer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christoph","family":"W\u00fcrtinger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andreas","family":"Korge","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2020,3,16]]},"reference":[{"key":"659_CR1","doi-asserted-by":"publisher","first-page":"1492","DOI":"10.1097\/BRS.0b013e3181a0934f","volume":"34","author":"M Aepli","year":"2009","unstructured":"Aepli\u00a0M, Mannion\u00a0AF, Grob\u00a0D (2009) Translaminar screw fixation of the lumbar spine: long-term outcome.
