Methods ： fifty paired embalmed cadaveric humeri ( twenty - five pairs : fourteen from male donors and eleven from female donors ) were scanned in medial - lateral ( ml ) and anterior - posterior ( ap ) position according to the humeral retroversion by ct. images of the humeri in the transverse planes at the lowest border of neck ( lbn ), 20mm and 40mm distal of lbn ( lbn - 20 、 lbn - 40 ), isthmus, head - neck anterior - posterior ( hn - ap ) were obtained. sixty - one extracortical and intracortical parameters were measured exactly by image analytic computer software that included offset, head position, head - shaft angle, head to tuberosity height ( ht ), head thickness, curvature radius, articular surface arc ( sa ), neck diameter, isthmus position, proximal and distal border of isthmus, maximum coronal and sagittal diameter of medullary canal and thickness of cortical bone in four planes, including lbn, lbn - 20, lbn - 40 and isthmus
