Adaption of Bone to Mechanical Loading
In loading, pure longitudinal, axial force such as compression slightly shortens and
widens the bone while tension lengthens and narrows the bone. Bending mainly
compresses the other side of the long bone and elongates the other. Bone is at its
weakest at coping with the shear forces, better at coping with tension, and at its
best for coping with compression [ 12 ]. Forces in habitual loading are most likely a
combination of more than one, however, [ 13 ]. The anisotropic nature of bone
reflects its function since bone structure is strongest in the primary loading con-
dition [ 14 ].
Research Methodology
1. Obtain the sample data
The geometrical data of real proximal human humerus bone in the format of
Digital Imaging and Communications in Medicine (DICOM) images of a 17-year-
old male, whose weight is 75 kg, is obtained from CT scan data. A single DICOM
file contains a header that stores information about the patient's names, the type of
scan, image dimensions, and the image data, which contains information in three
dimensions [ 15 ]. This DICOM data set is obtained from GE Signa HDXt 2008
Multi Channel 1.5 Tesla Superconducting Helium Cooled whole-body MR module
machine and contains a total of 909 slices. This machine can perform with highest
