A fracture of the lesser tuberosity. b) LBG fractures = incomplete fracture of the anatomical neck with extension into the lesser tuberosity (LB) with a fracture of the greater tuberosity. c) MBG fractures = incomplete articular fractures with an medial metaphyseal fragment at the humeral head (MB) with a fracture of the greater tuberosity. d) MBL fractures = incomplete articular fractures with an medial metaphyseal fragment at the humeral head (MB) with a fracture of the lesser tuberosity. e) MBT fractures = 4-Part B fractures appear which are MB fractures in combination with a fracture of both tuberosities (G and L = T) = MBT fractures.<p><b>Copyright information:</b></p><p>Taken from "Inter- and intraobserver reliability of the MTM-classification for proximal humeral fractures: A prospective study"</p><p>http://www.biomedcentral.com/1471-2474/9/21</p><p>BMC Musculoskeletal Disorders 2008;9():21-21.</p><p>Published online 17 Feb 2008</p><p>PMCID:PMC2275241.</p><p></p
