Mechanical properties of the human vertebrae between normal, post corrective and post operative

Human spine consists of 33 vertebrae. 7 cervical, 12 thoracic, 5 lumbar, 5 fused sacral vertebrae and 4 fused coccygeal vertebrae. These vertebrae generally increase in size from cervical to lumbar. Similar to the size, weight bearing capacity of the vertebrae is also higher. This weight bearing capacity of the vertebrae depends on both material properties (Bone mineral density) and geometric properties (connectivity of bone elements). Both are inter-related and together called as mechanical properties of vertebrae. When there is a structural change in the alignment of vertebrae due to congenital or neuromuscular or degenerative, it affects the mechanical properties of vertebrae. In this study we are going to deal with the mechanical properties of vertebrae affected by spinal deformities like Scoliosis and Kyphosis.
