Morphological characteristics of the surgical neck region in the proximal humerus at different ages

Abstract: Background The objective of the study was to demonstrate the cortical thickness character in the humeral surgical neck region using 3D cortical bone mapping technique and try to illustrate its morphological changes with age. Material and methods Normal individuals, including 11 volunteers younger than 18 years, 87 adult men and 46 adult women, were enrolled. The cortical thickness and height of the surgical neck region was measured with Mimic and 3… Show more

“…In patients in their 60 s, the density of the greater tuberosity (GT) in the shoulder with rotator cuff tears is 200 mg/cm 3 , while that on the healthy side is 300 mg/cm 3 14 . Furthermore, the cortical thickness of the proximal humerus is approximately 2 mm 15 . Therefore, The OB simulator was designed with an outer layer of 1.5 mm by reducing the thickness by 0.5 mm, the internal structure was designed with a gyroid shape infill to 15% to create a density of 200 mg/cm 3 .…”
