Methods:Fifty paired embalmed cadaveric humeri (twenty-five pairs:fourteen from male donors and eleven from female donors) were scanned in medial-lateral and anterior-posterior position according to the humeral retroversion by CT. Images of the humeri in the transverse planes at the lowest border of neck,20mm and 40mm distal of LBN(LBN-20、LBN-40), isthmus, head-neck anterior-posteriorwere 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, head thickness, curvature radius, articular surface arc, 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.
