Cervical spine pathologies Flashcards
what is cervical spondylosis
degenerative disc disorder affecting interbody joint, lower cervical spine most affected (C5-6, C6-7, C4-5), age groups 45+, onset= insidious or traumatic. Disc space narrowing, anterior osteophyte formation, lipping & irregularity of vertebral bodies
cervical spondylosis- patho-anatomical changes
loss of disc height due to disc dehydration and degermation, vertebrae approximate, formation of marginal osteophytes, increased WB on facet joints, possible nerve root entrapment and spinal cord compression due to degenerative changes
cervical spondylosis- symptoms and signs
symptoms- bilateral/unilateral neck pain, referred pain into shoulder/arm/head, this can be somatic referred pain or radicular referred if degenerative irritate a spinal nerve, neck stiffness
signs- decreased cervical ROM (rotation and SF most affected), pain on PAIVM on affected level, altered posture, dermatomal changes if nerve root involved, degenerative changes on X-rays
cervical disc herniation
caused by degenerative weakening of annulus- nucleus propulsus goes through, affects individuals in 30’s, C6-7 and C5-6 most common affected. Uncommon- IVD in Cx supported posteriorly by PLL and laterally by uncovertebral joints, nucleus pulposus is Cx is largely fibrocartilaginous
cervical disc herniation- risk factors
age, smoking, lifting heavy objects, diving
cervical disc herniation- source of pain and disc prolapse
source= tear of outer annulus, inflammatory process, can be bilateral issue with all 4 limb (affect gait)
disc prolapse- centrally, posterolateral, bulge
cervical disc herniation- symptoms
S&S depended on size and location, acute and rapidly worsening neck pain (central or unilateral), referred pain to scapula, pain worse on ext and prolonged flex activities (cough and sneeze), antalgic posture- head held in flex
cervical disc herniation- different positions symptoms
posterolateral and spinal nerve will produce- radicular referred pain into arm and hand (lateral canal stenosis), paraesthesia and or anaesthesia into UL
if prolapse is posterior and central spinal cord may be involved= myelopathy, may get signs of cord compression (central canal stenosis)
Facet OA
degenerative disorder affecting synovial joints, most common in >65 y/o
pathology- synovitis, disintegration of articular cartilage, osteophyte formation, joint space narrowing
Facet OA- symptoms and signs
symptoms- local- often unilateral pain, somatic pain referral into shoulder/scap region depending on levels affected, stiff neck
signs- decreased ROM into facet closed pack position- ext and ipsilateral SF/ rotation
pain reproduced on PAIVM affected levels
Facet OA- position of affected levels
C2-C3= posterior to ear on left side, C3-C4= pain on neck on right side, C4-5= pain on neck lower than C3, C5-C6= pain over right shoulder, C6-7= pain over scapula
Facet OA- X ray changes
cartilage destruction of facet joints, loss of joint space, osteophyte formation around joint margin, IVD and vertebral bodies normal
Cervical radiculopathy
links to disc prolapse= nerve irritated, 9 cervical nerve roots, emerge above corresponding vertebrae but below IVD
Cervical radiculopathy- lateral canal stenosis
narrowing of I-V formation, causes nerve root compression and irritation, neurological changes
Cervical radiculopathy- nerve roots as source of pain
irritation of cervical nerve root in the IV foraminal usually in the medial half by: inflammation, posterolateral disc prolapse, degenerative changes of facet joints, most common affects C5/6/7
