Thoracic Spine Biomechanics Flashcards
thoracic is more blank than lumbar but blank than cervical
mobile, less
if we rotate one way we side bend blank
other way
thoracic is same arthro/osteokinematics as blank
lumbar, cervical
name a rotated vertebrae by looking at blank not blank
anterior body, transverse process
rule of threes t1 t3
tp is level with sp
rule of threes t4-6
sp are half level inferior to tp
rule of threes t7-9
sp 1 level inf to their tp
t10 rule of threes
sp is a segment inferior to tp
rule of three t11
sp is half segment below tp
t12 rule of three
sp is level with tp
check rein to flexion of thoracic
PLL, suprapinous, infraspinous, ligamenta flava, anterior vertebral body,
annulus fibrosis resists blank load
tension
check rein to extension
ALL
check rein to sidebending
ribs, intercostal muscles contralateral
check rein to rotation
bilateral intertransverse tension, iv disc shear (friction), iv disc tension loaded
