cervical spondylosis and neuropathies Flashcards
what is cervical spondylosis?
the specific terms for osteoarthritis of the cervical spine due to degeneration of the disc or facet joints
what are the S&S of cervical spondylosis?
spontaneous onset of neck pain
cervical muscle pain and spasm
headaches or occiptial pain - referred pain
weakness or numbness
radiating arm pain
reflex changes
- increased in myelopathy
- decreased in radiculopathy
what is a cervical radiculopathy?
radiating arm pain following a single cervical nerve root distribution due to mechanical compression of a nerve root as it exits the spinal cord
what is a cervical myelopathy?
syndrome of neurological deficit in upper and lower extremities resulting from increased spinal cord pressure in the cervical spine due to degenerative changes in the disc and/or facet joints
what would a radiculopathy at C5 root (C4/5 disc) cause
- Weak deltoid & supraspinatus; ↓supinator jerks; numb elbow.
what would a radiculopathy at C6 (C5/6 disc) root cause
- Weak biceps & brachioradialis; ↓biceps jerks; numb thumb & index finger.
what would a radiculopathy at C7 (C6/7 disc) root cause
Weak triceps & finger extension; ↓triceps jerks; numb middle finger.
what would a radiculopathy at C8 (C7/T1 disc) root cause
Weak finger flexors & small muscles of the hand; numb 5th & ring finger
below the level of a myelopathy there may be UMN signs indicating cord compression. What are they?
Spascity
weakness
brisk reflexes
upgoing plantars
what investigations are done in cervical spondylosis?
Cervical MRI
- bone destruction
- spinal cord or nerve compression
Cervical X-ray
- degenerative joint disease
Cervical myelogram
- disc herniation or nerve root compression
how is cervical spondylosis treated?
analgesia PT oral corticosteroids surgical decompression - laminectomy or laminoplasty immobilsation in hard collar transforaminal steroid injections
how does radial nerve palsy present?
painless wrist and finger drop
sensory change over radial distribution
weakness of which muscles are involved in radial nerve palsy?
extensor carpii radialis longus - wrist extension
extensor digitorum communis - finger extension
brachioradialis - elbow flexion in mid pronation
how does ulnar nerve palsy present?
claw hand and inability to cross fingers
for other nerve palsies look at notes lol
