Description
Summary:Age-related changes in the medial column (MC) of the proximal humerus have a major impact on fracture management; however, the changes in the morphological features remain unclear. This study aimed to investigate the age-related changes in the morphological features of MC and present the morphological grading. One hundred computed tomography (CT) images of the proximal humerus of 100 individuals (19-95 years) were retrospectively obtained. The individuals were categorized into five age groups to quantify the differences among different ages; the youngest group (18-44 years) served as the baseline group. Parameters of the morphological features were measured on CT images with multiplanar reconstruction based on an explicit definition of MC, including length, thickness, width, oblique thickness (D ), humeral head diameter (D ), and ratio (R ) of D to D . The morphological grading of MC was presented based on the value of R deviating different standard deviations (SD) from the mean value in the baseline group. Significant negative correlations were observed between age and the morphological parameters of MC (r ranged from -0.875 to -0.926; all
