Q

Where is the Carotid pulse felt and what is the rule for feeling this pulse; what can we assess here with stethoscope?

A
  • Medial to the SCM. Inferior to the corner of the jaw. Repeat on opposite side

Q

Proper setup for assessing Jugular Venous Pressure?

A
  1. Place pillow under patients head to relax SCM’s
  2. Raise head of exam table to 30° and turn pt’s head slightly away from the side you are examining
  3. Identify the IJV using tangenitial lighting.
  4. Identify the highest point of pulsation. Extend object horizontally from teh apex. Place a ruler vertical from sternal angle ot create a right angle w/ the horizontal object
  5. Distance in cm above the sternal angle (right atrium) is the JVP

Q

For thyroid palpation how do we locate, what do we have the patient do, where do we palpate?

A
  • Isthmus overlies 2nd-4th tracheal rings
  • Have patient flex neck slightly to relax SCMs
  • Place fingers of both hands on pt’s neck so that index fingers lie just below cricoid cartilage. Have the pt swallow so thyroid rises up under finger pads.
  • Observe for contour and symmetry
  • Displace trachea to right and palpate right lobes. Repeat on left. Anterior surace of a lateral lobe is approximately the size of the distal phalanx of thumb and feels somewhat rubbery

Q

What is Central Neuropathy; common sites?

Study These Flashcards
A
  • Nerve entrapment by MSK or myofascial tissue producing paresthesias in area of the distribution of the nerve and creates sensory dysfunction/pain and may also decrease muscle strength.
  • Common sites: intervertebral foramen and thoracic outlet
18
Q

What is the Compression Test for central neuropathy and positive test?

Study These Flashcards
A
  • With head in neutral position, add an axial loading force caudally looking for UE pain, paresthesias, or numbness
  • (+) test is reproduction of symptoms (pain/paresthesia in distribution of nerve root)
19
Q

What is the Spurling’s Test for central neuropathy and positive test?

Study These Flashcards
A
  • Tests nerve root compression/irritation.
  • Tested w/ axial force in neutral, then extension, then SB/rotation toward.
  • Test of high specificity
  • (+) test: reproduction of symptoms (pain/paresthesia in distribution of nerve roots)
20
Q

What is a Valsalva Test, positive test, and what does it indicate?

Study These Flashcards
A
  • Pt holds breath and bears down (Valsalva maneuver), which increases intrathecal pressure
  • (+) test is increased symptoms (pain/paresthesa in distribution of nerve root)
  • Indicates: space occupying lesion in cervical canal
21
Q

What are the boundaries of the thoracic outlet; best thought of a what 3 zone; structures inside; importance of thoracic duct and right lymphatic duct?

Study These Flashcards
A

Boundaries: 1st rib, 1st thoracic vertebra, manubrium

3 zones: scalene triangl, costoclavicular space, retropectoralis minor

Structures: brachial plexus, subclavian V, subclavican A, thoracic duct (L side)

* Thoracic duct drains majority of body. Right lymphatic duct drains body’s RUQ

22
Q

What is the Roos or EAST test; positive test; indicates what?

Study These Flashcards
A
  • Abduct shoulder to 90° and ER w/ elbow flexed to 90°
  • Pt instructed to open and close fist for up to 3 mins.
  • (+) test: reproduction of symptoms (pain/paresthesia)

Indicates: Thoracic outlet syndrome, specifically compression of subclavian A

23
Q

What is the Adson test; positive test; indicates what?

Study These Flashcards
A
  • Locate radial pulse on affected arm. Physician ABduct, extends, and ER the shoulder while palpating radial pulse.
  • First, pt’s head is extended and rotated toward affected side. Then the patient’s head is extended and rotated away from affected side
  • (+) Test: Loss or change in pulse; reproduction of symptoms (pain/paresthesia)

Indicates: Thoracic outlet syndrome, specifically compression of subclavican artery between scalenes (when looking away from the affected side) or 1st rib/cervical rib (when looking toward affected side)

24
Q

What is Wright’s Hyperabduction Test; positive test; indicates what?

Study These Flashcards
A
  • Physician locates and monitors the radial pulse on the affected side. ABDuct the patient’s arm above his or her head w/ some extension
  • (+) Test: Loss or change in pulse; reproduction of symptoms (pain/paresthesia)

Indicates: Thoracic outlet syndrome, specifically neurovascular entrapment by pectoralis minor

- Place pt **supine** and **flex hip** and **knee** to **90°**. Attempt to **passively** **extend** the **leg at the knee** - **(+) Test:** Increases resistance to extension and pain behind knee, +/- back pain radiating to posterior thigh (sources vary) **Indicates:** Meningeal/dural irritation \* Sensitivty is low (5%) and specific data is limited
29
Cervical spinal cord injuries can occur in ANY sport, but which 3 in particular; which kind of loading force accounts for over half of these injuries and what about this type of force increases injuries?
- Particularly **football, hockey, lacrosse** - **Axial load** accounts for over half of c-spine inuries - Neck **flexion** to **30°** --\> **lordosis lost** and protective soft tissues no longer protective
30
What is a Jefferson Fracture?
Axial Compression --\> C1 fracture
31

- Wedge fracture - Flexion and compression injury
32
What is a Dens Fracture?
C2 odontoid fracture at junction of process and body. Often requires surgery
33
What is a Hangman's fracture; caused by?
Hyper**extension** injury ---\> C2 bilateral arch fracture
34
What causes a spinous process fracture?
Hyper**extension** or **avulsion force** from a **muscle contraction**
35
What is a Clay Shoveler's fracture?
C6 or C7 fracture
36
What causes an Anterior Subluxation?
Flexion injury --\> Facet dislocation w/o fracture
37
