SPINE KINETICS (BIOMECHANIS OF SPINE)Physiotherapy Tutorial Instagram:   / _movementscience_   linked in :   / adhip-nadkarni-5b45241a6   twitter :   / adhip_nadkarni   summary of the video with the time for reference: 1.Axial compression 2:19 -Gravity, GRF, Muscular fore, ligament -Compressive force (25-55)% is taken up by cancellous bone before 40 and after that its taken up by cortical bone -Zygophyseal joint takes about (0-33)% forces are taken up which varies with region and posture -Nucleus exerts an outward pressure which is countered by anulus and an equilibrium is created so that forces are absorbed -Disc exhibits property of creep -Diurinal changes in thickness of the disc 2.Shear forces 7:00 -Translatory forces on object in opposite direction -Acts on the mid plane of the disc -vertebra at lumbar spine have facets in sagittal plane which resists shear force 3.Axial Rotation 8:28 -Stiffness is given to the vertebra against torsion by Anulus according to its orientation, facet and ligaments -Apart from that it has high risk for rupture when rotation is combined with flexion and compression 4.Bending force 10:08 -Commonly seen in flexion and extension -Creep is exhibited by disc -If structures go past the toe region the structure cannot come back to its orignal position and there are high chances of injury -Lateral flexion movements are stabilized by inter transverse ligament #biomechanicsofspine #spinebiomechanics #vertebralcolumnbiomechanics
