TomodensitométrieLa tomodensitométrie (TDM), dite aussi scanographie, tomographie axiale calculée par ordinateur (TACO), CT-scan (CT : computed tomography), CAT-scan (CAT : computer-assisted tomography), ou simplement scanner ou scanneur pour l'appareil, est une technique d' qui consiste à mesurer l'absorption des rayons X par les tissus puis, par traitement informatique, à numériser et enfin reconstruire des images 2D ou 3D des structures anatomiques.
NonunionNonunion is permanent failure of healing following a broken bone unless intervention (such as surgery) is performed. A fracture with nonunion generally forms a structural resemblance to a fibrous joint, and is therefore often called a "false joint" or pseudoarthrosis (from Greek pseudo-, meaning false, and arthrosis, meaning joint). The diagnosis is generally made when there is no healing between two sets of medical imaging, such as X-ray or CT scan. This is generally after 6–8 months.
