spine curvatures
LKLK
vertebral unit?
2 adjacent vertebrae and associated vertebral disc
rule of 3s?
t1-t3: spinous and transverse processes same level
t4-t6: spinous 1/2 level below transverse process
t7-t9: spinous at the level of the inferior transverse processes
T10: same as t7-t9
T11: same as t4-t6
t12: same as t1-t3
superior facet orientation of vertebrae?
Cervical = BUM (backwards, upward, medial) Thoracic = BUL (backwards, upward, lateral) Lumbar = BM (backwards, medial)
Bumblebee
anterior longitudinal L?
connects anterolateral aspects of vertebral bodies and IV discs
limits extension
posterior longitudinal L?
runs within vertebral canal and connects posterior vertebral bodies
resists hyperflexion and prevents herniation of nucleus pulposus
ligamentum flava?
connects laminae of adjacent vertebrae
interspinous L?
connects spinous processes
intertransverse L?
connects transverse processes
iliolumbar L?
connects base of lumbar spine to ilium
rotatores muscles?
longus - b/w transverse processes skipping 1 vertebrae
brevis - b/w transverse processes of adjacent vertebrae
extends thoracic spine bilaterally, rotates thoracic spine to opposite side unilaterally
multifidus muscles?
insert spinous processes skipping 2-4 vertebrae
extends spine bilaterlally, side-bends and rotates to opposite side unilaterally
semispinalis muscles?
transverse to spinous processes
extends thoracic/cervical spines and head bilaterally, side bends and rotates opposite side of head/cervical/thoracic
coupled motion?
motion about 2 axes, principle motion cannot be produced w/o the associated motion
linkage?
relationship of joint mechanics, linking joints increases ROM
results of spinal SD?
reduce efficiency
impair flow of fluids
alter nerve function
create structural imbalance
vertebral motion nomenclature?
motion is the movement of the anterior/superior surface
excessive motion/restriction is in reference to the top vertebrae in the unit (excess motion of L2 is the motion of L2 on L3)
who described physiological motion of the spine?
Fryette 1918
developers of principles of spinal motion
principles 1 and 2 = fryette (1918)
principle 3 = Nelson (1948)
type 1 Fryette mechanics?
in neutral range, sidebending and rotation are coupled in opposite directions (rotation towards convexity) (tends to be group of vertebrae)
Type One Neutral Group Opposite (TONGO)
type 2 Fryette mechanics?
in flexion/extension, sidebending and rotation are in the same direction (rotation towards cocavity) (tends to be single vertebrae)
Type Two Ø (non-neutral) Single Same (TTOSS)
naming SDs w/ Fryette
if neutral; left sidebending restriction = right rotation restriction, etc
if f/e; left sidebending restriction - left rotation restriction, etc
abbreviated: T3-8 N Sr Rl (Vs/state/restrictions)
type 3 Fryette mechanics?
if motion restricted in one direction, it will also be restricted in other directions
if motion improved in one direction, it will also be improved in other directions
summary: movement in any plane modifies movement in other planes
spinal landmarks?
spine of scapula - T3 spinous/transverse
inferior angle of scapula - t7 spinous/t8 transverse
iliac crest - l4
