WVSOM -- opp1

WVSOM -- OPP1 -- Cervical Spine Dysfunction

QuestionAnswer
What is the function of cervical vertebrae (3)? serve to stabilize and support the head. Permit motion of the head and neck. Provide protection and housing for the cervical spinal cord and nerve roots and vertebral artery.
What kind of symptoms occur with cervical spine dysfunction? head, neck and upper extremity
What is the most common mechanism of injury for neck pain? MVA
What does optimum pain management require for neck pain? requires identification and appropriate treatment of somatic dysfunction
What kind of curve is the cervical spine? lordotic curve
What do uncinate processes do and where are they? C3-7. Add support to cervcial spine and helps prevent herination
What is the Occiptal antlantal segment? C0-C1
What is the antantal-axial segment? c1-2
What is the 2 functions of the cervical muscles? stabilize spine and control effects of gravity. Integrate and C-Spine movement with thoracic rib, and upper extremity motions.
What are the two major muscular groups of the cervical spine? Flexors and extensors
Where do the cervical nerves exit? above corresponding cervical vertrae until C8 where the nerve exits below the 7th vertebrae.
What is the most common herniation in cervical spine? C5-C6 disc (C6 root)
What is the Foramen transversaruim? vertebral artery found in C1-7
Where are bifid spinous processes found? C2-C6
What enables flexion and extension? bilaterally muscle activity
What enables sidebendinga nd rotation? muscles acting unilaterally
Do Fryette’s mechanics apply to the cervical spine? no
What is the primary roation of the Antlantal Axial segment? rotation
What is the primary movement of the Occipital-antlantal segment? flexion and extension
What happens to rotation in the OA joint when it is sidebent? rotation in the OPPOSITE direction
What is the degree of articulation of facets on the oblique plane? 45degrees
How is rotation affected when it is sidebent for typical cercvical vertebrae? same side
Where does most cervical sidebending occur? lower cervical
What do facets do during typical flexion? open
What do facets do during typical extension? close
What kind of dysfunction is seen in AA joint? entirely rotation
How much flexion and extension is at OA joint? 50%
How much rotation is at AA joint? 50%
How much rotation and flexion/extension is found in the typical cervical? 50%
What are the 4 things done during examination of the neck? 1. Posture and movement. 2. Rotation, lateral bending, flexion and extension. 3. Palpation. 4. Assess for radiculopathy
What is dorsokyphosis? depression, upper-crossed postural abnormality. Seen with advanced age
What may sluggish movement indicate? sfibromyalgia, OA, cervical strain
What is torticolis? acute muscle spasm, possible HNP
What is normal rotation? 80 degrees
What is normal sidebending? greater than 45 degrees
What is normal flexion? greater than 50 degrees
What is normal extension? greater than 60 degrees
What is first movement to show defecit? rotation
What is the most sensitive indicator to pathology intrinsic to the neck? loss of rotation
What should you do if angle of rotation is less than 90 degrees? neurological exam of upper extremities as well as x-rays.
What is tested with passive range of motion? rotation, sidebending, flexion, and extension
What should you consider if countour is malaligned? rotation, facet dislocation and fracture
Where is osteoarthritis usually seen? C5-C6
What may be seen if there is osteoarthritis? tenderness, stiff and possibly enlarged.
What do you palpate with bone? bony tenderness, spinous processes and facet joint
What do you palpate with muscle? paraspinous muscle, trapezius muscle
What is the most commonly irritated neck muscle? trapezius
What does the trapezius muscle do in respects to the neck? attaches to all 7 spinous processes to distal acromion process
What is spurling maneuver? tap or press on top of head in with extension and sidebending
What innervates the deltoid m.? c5
What innervates wrist extensors? c6
What innervates finger flexors? c8
What innervates interossei mm. T1
What innervates biceps? c5
What innervates brachioradialis? c6
What innervates triceps? c7
What is VAD? vertbral artery dissection. Unpredictable, rare complication of neck thrusts. 1/20,000
How do vertebral arteries angulate? angulates 3 times at 90 degrees around the atlas as it ascends into the cranium thru the foramen magnum
What is Wallenberg’s Test? patient is supine and flexion, extension, etension with rotation right and extension with rotation left are held for 10 seconds
What is a positive Wallenberg’s Test indicate? nystagmus, dizziness, light headedness, visual disturbance
What is contraindicated with a positive wallenberg’s test? HVLA
What does Wallenberg’s Test test? vertebral aretery problems
What are the symptoms of cervical radiculopathy? paracervical tenderness with abnormal upper extremity exam. Loss of full ROM especially in rotation with positive spurling sign. Vertical traction will provide relief.
90% of radicular symptoms are due to ? cervical OA
You evaluate a patient who has limited sidebending to left which is worse in extension at C5. What is the diagnosis? FRS (r)
On physical examination you not mild noss of sensation in the region of the thumg, +1/+2 reflexes at brachioradialsi and 4/5 strentth in wrist extension. The affected nerve root exits the C-spine? below C5
