Sahani, Rishikant (2015) Finite Element Analysis of Human Lumbar Vertebrae in Pedicle Screw Fixation. MTech thesis.
In totality of 100%, near about 85% of adult’s falls back pain, which directly related to their daily assignments and activities and 25% of people, reported lower back pain,which is associated with the vertebral compression. Spinal de-generation is also a medical situation which directly affecting men and women of different age groups.Spine injury is mostly found on vertebrae L1– L5 and corresponding intervertebral disk and in this analysis, the purposes of the present research are conclude the appropriate dimensions of pedicle screw (diameter and length) for its fixation in L2–L3-L4 vertebral region. In this analysis pedicle screw of Titanium with different diameters 5, 5.5, 6.0, 6.5 mm. and length 45, 50 mm have been considered. Further to this Finite element analysis (FEA) with boundary condition, i.e. fixed bottom surface of the L4 vertebrae and loads were applied on top surface of L2 vertebrae. The different loading condition has been considered for various body weights. Results were analyzed to provide appropriate pedicle screw size.
