Chapter 25 - The Spine Flashcards
facet joint dysfunction
localized pain over the joint, can be acute or insidious onset. pain in all movements other than flexion.
suspect facet joint dysfunction, what tests should be performed. what other injuries need to be ruled out?
disc lesions, spondy, stenosing etc
perform tests for disc lesions such as quadrant, valsalva, tension signs, SLR test, etc.
Pain patterns and symptoms of facet joint dysfunction
pain in all movements except flexion
spasming muscles
may be degenerative in nature causing nerve entrapment and associated problems
Lumbar Disc Pathology
rupture - acute onset
can also be degenerative
lumbar disc pathology pain patterns
pain at disc area - also pain along spinal nerve root.
paint down low back and through butt and thigh, possibly into the food
may be limited in all motions
when suspecting lumbar disc problem, what tests?
valsalva, SLR test, well cross SLR, milligram’s, tension signs, femoral nerve tension sign,
-tests that cause stretching nerve, or look for ‘space occupying lesion’
disc lesion - what imaging
MRI
DDx for disc lesion
spondy, stenosis, prirformis syndrome, facet joint dysfunction
Lordosis
increase curvature of lumbar
Kyphosis
increase curvature of thoracic
briefly describe the anatomy of the spine
cervical, thoracic, lumbar, sacrum, cocyx 7 C 12 T 5 L 33 vertebrae
lordotic curve
kyphotic curve
lordotic curve
articulation between the vertebral bodies is what type of joint? what movements occur here
cartilaginous
forward gliding, lateral gliding, compression and distraction
facet joints in the vertebrae are what type of joint?
synovial joint.
name the major ligaments of the spine. what movements do they restrict?
anterior longitudinal - restrict extension
posterior longitudinal - restrict flexion
supraspinous - attaches at every spinous process - limits flexion and rotation of the spine
muscles that extend the spine
erector spinae
- iliocostalis
- longissimus
- spinalis
spinal cord anatomy
extends from foramen magnum to L1-L2 where it forms the caudal equina
how many pairs of spinal nerves
31
roots of nerves
anterior (motor)
posterior (sensory)
injuries occurring above L3 - what must one worry about?
spinal cord damage
name the plexuses and the nerves they involve
Cervical ( C1-C4 ) Brachial (C5-T1) Lumbar (L1-L4) Sacral (L4-S4) Coccygeal (S4-S5)
name the nerves of brachial plexus
axillary radial msuculocutaneous ulnar median
axillary - perform nerve test
abudcts arm , laterally rotates arm
radial - perform nerve test
extends/flexes elbow
extends writs and fingers
thumb muscles
musculotaneous perform nerve test
flexes arm, and forearm
ulnar - perform nerve test
flexes wrist and fingers, abducts/adducts fingers
thumb muscle - palmar muscles
median perform nerve test
pronates,
flexes wrist and fingers
-thumb musclse and thenar/palmar muscles
movements of the vertebral column
flexion, extension, lateral flexion, rotation
trunk rotation
external/internal obliques
lateral flexion
quadratus lumborum, obliques, lats, iliopsoas, rectus abdominus on involved side
flexion
75% occurs at lumbosacral joint
lengthening of deep and superficial back muscles
contraction of abs, obliques and hip flexors
football helmets do not protect against what?
neck injuries
what is spearing?
athlete uses the helmet as a weapon by striking the opponent with its top
most serious football cervical injuries result from what MOI?
axial loading while spearing
neck flexion at the time of contact can cause what type of injuries
fracture or dislocation
most catastrophic diving accidents happen in how deep of water
less than 5 feet with arms not extended in front of face
read NATA positions statement on head down tackiling and spearing
now
managing low back pain
avoiding stress, correcting biomechanics, correct lifting techniques, core stabilization
when taking the history of the spine, what is most critical to know? give examples of questions
if the spinal cord was damaged
- what happened?
- did you hit someone with or land directly on top of your head?
- were you knocked out or unconscious?
- pain in your neck? tingling or numbness anywhere?
- equal muscle strength in hands?
- unable to move ankle or toes?
what are you looking for in the observation portion of a spinal evaluation
posture abnormalities look from all angles kyphosis forward head swayback - anterior shifting of the pelvis lordosis scoliosis flatback level shoulders, symmetry -ask the patient to perform all movements - note painful ones -level pelvis -unusual curve in lumbar area -sitting, standing, and lying
common cause of thoracic pain
dysfunction of joints - usually facet joint
-associated with increased pain when placing chin on chest
