Neck 1 Flashcards
(25 cards)
What is inflammatory arthropathy?
Rheumatois arthritis ankylosing spondylitis polymyalgia rheumatica inflam. bowel disease - ulcerative colitis, chrohns systemic lupus erythematosus osteomyelitis
Define boundaries of the neck
Superiorly - Sup. nuchal line
Inferiorly - an imaginary line through tip of SP of T1
Laterally - sagittal planes at lateral borders of the neck
What is radiculopathy?
A neurologic condition characterised by sensory & motor loss or impaired reflexes in a segmental distribution
Mainly loss of function - not pain
generally a C spine nerve is compressed/rendered ischemic
What is cervical radicular pain?
Pain perceived deeply, not restricted to cutaneous afferents
Pain that explicitly relates to compression of a dorsal root ganglion
What is somatic referred pain?
Pain perceived in a region innervated by nerves other than those that innervate the source of pain
In the neck patterns of referral are usually a function of whether the source is upper or lower
Where will you feel referred pain from interspinous muscles?
Upper limb - referrals from Z joints and cervical IVDs are perceived in largely same distributions
Describe sequestration
To set apart, detach or separate a small portion of tissue from the rest - may occur naturally or iatrogenically
Vertebrae injured - what may be the cause?
trauma, fracture, tumour, bone disease
Joint/synovial membrane injured - what may be the cause?
spondylosis, inflammation, infection, dislocation
Capsule injured - what may be the cause?
sprain, inflammation
Ligaments injured - what may be the cause?
damage to OA/AA membranes, alar,cruciate,tectorial membrane, ALL,PLL,intertransverse, flavum, inter/supraspinous
Musculotendinous problem
pre & post vertebral muscles, strain, sprain, imbalance, Tp, TrP, muscle dysfunction/disease
Disc injured - what may be the cause?
discitis, internal disc disruption, prolapse
Dura injured - what may be the cause?
infection, compression, inflammation
Neural injury - what may be the cause?
IVF compromise, central canal compromise, mobility, inflamm., radiculopathy, radicular pain
Somatic referred - what may be the cause?
Intracranial bleed, tumour/abcess, meningitis, TrP
Visceral referred - what may be the cause?
Heart, oesophagus, lung, thyroiditis, cervical adenitis
Steps involved in IDD
Fraction of the vertebral end plate
Prolapsed nuclear material
inflammatory response
degradation of nuclear matrix
bracing effect reduced, AF bears compression alone
AF may creep under compression
narrower disc space, isolated disc resorption
Define spondylosis
'wear & tear' osteoarthritis joint arthrosis degenerative joint disease Characterised by a progressive loss of joint cartilage, subchondral sclerosis within synovial joints osteophytosis
What are the clinical features of cervical disc disease?
Unilateral pain
Usually starts in C spine area, may diminish but commonly extends to scapula, shoulder, upper arm, possibly forearm & hand
Painful or restricted neck movements may be intermittent over several months
May be paraesthesia initially but DRG may become involved provoking radicular pain
What is cervical mylopathy and its clinical features?
Sagittal diameter of vertebral column is less than 11mm suggesting spinal stenosis - could be from IVD degen. OA of facet joints, thickening of lig. flav. spondylolythesis
Clin features - neck pain, radicular pain in arm, neuro sym in upper extrem & lower extrem,
Classic picture - numbness in hands with weakness & spasticity/loss of function in lower extrem.
List 6 serious but rare causes of neck pain
Vertebral tumours meningitis osteomyelitis discitis septic arthritis epidural abscess
3 DDxs of vertigo and list 2 signs/sym that would rule them out
BPPV (Benign paroxysmal positional vertigo) - disorder of the inner ear, debris in semi-circular canal, nystygmus on performing Hallpike - defining trait
Menieres disease - endolymphatic hydrops, disorder of vestibular system - attacks are greater than 20 mins, fluctuating or permanent
Hyperventialtion syndrome - breathing too deeply/rapidly, may present with chest pain/tingling in fingertips
Sensitivity: If a person has a disease, how often will the test be positive (true positive rate)?
Put another way, if the test is highly sensitive and the test result is negative you can be nearly certain that they don’t have disease.
A Sensitive test helps rule out disease (when the result is negative). Sensitivity rule out or “Snout”
Sensitivity= true positives/(true positive + false negative)
