1

Temperomandibular Joint: 

What CN is it associated with?

How do you palpate it?

 

CN V

Place tips of index fingers just in from of tragus of each ear and ask pt to open mouth. Fingertips should drop into joint spaces as mouth opens. Check for smooth range of motion. Note any swelling or tenderness. Snapping or clicking may be felt or heard in normal people. 

2

ROM for neck

We seem to use extension instead of hyperextension

Shoulder ROM

No hyperextension in Bates  

Flexion: "Raise your arms in front of you and overhead"  

Extension: "Raise your arms behind you"  

Abduction: "Raise your arms out to the side and overhead"  

Adduction: "cross your arm in front of your body"

Internal Rotation: "Place one hand behind yoru back and touch your shoulder blade" (could also be as pictured)  

External Rotation: "Raise your arm to shoulder level; bend your elbow and rotate your forearm to the ceiling" OR "Place one hand behind your neck or head as if you are brushing your hair"

Fingers: ROM

Flexion: Make a tight fist with each hand, thumb across knuckles

Extension: Extend and spread the fingers  

Abduction: spread fingers apart  

Adduction: Bring fingers back together

 

12

Thumbs: ROM

Flexion: move thumb across palm, touch base of 5th finger

Extension: move thumb back across palm and away from fingers  

Abduction: place fingers and thumb in neutral position with palm up, then have patient move thumb anteriorly away from the palm  

Adduction: bring thumb back to palm  

Opposition: touch thumb to each of fingertips

Grading Muscle Tone & Strength

0 - No muscular contraction detected

1 - A barely detectable flicker or trace of contraction

2 - active movement of body part with gravity eliminated

3 - Active movement against gravity

4 - Active movement against gravity and some resistance

5 - Active movement against full resistance without evident fatigue. This is normal muscle strength

14

Tinel's Test

Positive suggests carpal tunnel 

For median nerve compression. Lightly tap overcourse of median nerve in carpal tunnel. Positive: aching & numbness in median nerve distribution

15

Phalen's Test

For carpal tunnel

ask pt to hold wrists in flexion 60 seconds. OR backs of both hands together to form right angles (compresses median nerve)

23

Straight leg raise

provider passively elevates straight leg to see if any pain is produced in back and down leg. Seated or supine. 

Positive for lumbar radiculopathy if pain radiates down leg in radicular pattern

24

Thomas Test

with full hip flexion, look for full extension of opposite hip and flattening of lumbar lordosis; repeat w/ other leg

Measure distance between affected thigh and table

Physiologic in first 3mths of life

Checking for hip flexion contractures

25


Bulge Test

With your dominant hand, milk down towards the patella and then hold pressure. Now press the medial aspect of the knee to force any fluid within the joint laterally. Now, take your hand and press quickly along the lateral (i.e., opposite) aspect of the knee. If you see a fluid wave medially, that is a positive bulge sign. 

 if bulge present, you would check for ballottment. 

A image thumb
26

Ballottement: knee

For larger effusions

compress suprapatellar pouch and “ballotte” or push the patella

sharply against the femur. Watch for fluid returning to the

suprapatellar pouch.

27

Collateral ligament assessment: Valgus Test

MCL

abduction. With patient supine and knee slightly flexed, move thigh about 30 degrees laterally to the side of the table. Place one hand against lateral knee and stabilize the femur and the other hand around the medial ankle. Ush medially against the knee and pull laterally at the ankle to open the knee joint on the medial side (valgus stress). Pain or gap in medial joint line points to ligamentous laxity and a partial tear of the medial collateral ligament. Most injuries on medial side. 

genovalgum: "gum between your knees"

A image thumb
28

Collateral ligament assessment: Varus stress 

LCL

adduction. With thigh and knee in same position, change your position so you can place one hand against medial surface of the knee and push other around the lateral ankle. Push laterally against the knee and pull medially at the ankle to open the knee joint on the lateral side

genovarum: bow-legged

29

McMurray Test

Hold heel. Trap meniscus between tibia and femoral condyle. Knee hyperflexed and go back and forth w/ ankle to trap meniscus. To test medial meniscus, feel medial side w/ fingers.  Keep knee hyperflexed with ankle inversion and extend in varus position. To test lateral meniscus, feel lateral side w/ fingers. Knee hyperflexed with ankle eversion. Leg in valgus position and extend. Feel for pop/click. If pain with pop/click, this is a positive McMurray. (Tests Meniscus) 

 

Click or pop along medial joint w/valgus stress, external rotation and leg extension suggests a probably tear of posterior portion of medial meniscus. Tear may displace meniscal tissue, causing “locking” on full knee extension. McMurray + locking: medial meniscus tear 8.2 and 3.2 times more likely

ACL/PCL assessment: Drawer Test: (Anterior and Posterior)

w/ pt's knees bent and feet flat on table

Cup hands around knee w/thumbs on medial and lateral joint line and fingers on medial and lateral insertion of hamstrings. 

pull lower leg forward (anterior test) and push it back (posterior test)

A image thumb
31

Lachman Test

Place knee in 15 degrees of flexion and external rotation. Grasp distal femur on lateral side w/one hand and proximal tibia on medial side w/other. With thumb of tibial hand on joint line, simultaneously pull the tibia forward and the femur back. Estimate degree of forward excursion.

  • Heel down shin - length of knee to great toe
  • RAMS w/each hand (pronation, supination) or thumb finger to finger
  • Romberg
  • Pronator Drift
  • Tandem Walking
  • Heel walking

  • Gait

36

Romberg

Feet together, eyes open. Close them 30 to 60 seconds.  Excessive swaying/falling. Guard patient!

37

Pronator Drift

20 to 30 seconds, arms straight forward, palms up. Eyes closed. Tap briskly telling them to maintain horizontal position.

38

Gait descriptions

even

ataxia (jerky, unsteady)

dystonia

antalgic (limping b/c hurts)

39

Types of Joints

Synovial: freely movable (e.g., knee, shoulder)  

Cartilaginous: slightly moveable (e.g., vertebral bodies of the spine  

Fibrous: immovable (e.g., skull sutures)

40

Articular Structures

include joint capsule and articular cartilage, synovium and synovial fluid, intra-articular ligaments, and juxta-articular bone.

Articular disease typically involves swelling and tenderness of entire joint and limits both active and passive ROM d/t either stiffness or pan

41

Extra-articular structures

LIgaments: collagen fibrils, rope-like, connect bone to bone  

Tendons: collagen fibers connecting muscle to bone

Bursae: pouches of synovial fluid that cushion movement of tendons and muscle over bone or other joiint structures

extra-articular disease typically involves selected regions of joint and types of movement

42

Types of synovial joints

Spheroidal (ball & socket): e.g., shoulder and hip  

Hinge: IP joints of hand and foot, elbow  

Condylar: knee, TMJ

43

Low back pain

85% is idiopathic. Usually d/t muculoligamentous injuries and age-related degenerative processes 

44

Back pain: midline or off the midline

midline: musculoligamentous injury, disc herniation, vertebral collapse, spinal cord metasteses, and rarely, epidural abscess 

off the midline: muscle strain, sacroiliitis, trochanteric bursitis, sciatica, hip arthritis; also renal conditions e.g., pyelonephritis or stones

45

Cauda equina syndrome

from S2-4 midline disc or tumor

consider if patient c/o bowel or bladder dysfunction (usually urinary retntion w/overflow incontinence), especially if saddle anesthesia or perineal numbness

46

Pain in one joint, consider...

injury, monoarticular arthritis, possible tendinitis, or bursitis. Lateral hip pain near greater trochanter suggsts trochanteric bursitis

47

polyarticular pain: always ask about pattern of involvement

Migratory or steadily spreading? Symmetric?

Migratory: consider rheumatic fever, cgonococcal arthritis

Progressive additive & symmetric: rheumatoid arthritis

 

48

Severe pain, rapid onset in a red swollen joint, consider...

acute septic arthritis or gout. In children, consider osteomyelitis in bone contiguous to a joint

49

Joints: pain swelling, loss of active and passive motion, or "locking", consider....

articular joint pain

50

Joints: loss of active but not passive motion + tenderness outside the joing, consider...

nonarticular pain

51

At what age is peak bone mass reached and what is the speed of age related bone degeneration?

30 yo

Age related declines in estrogen and testosterone cause initially rapid bone loss which later becomes slow and continuous

52

Palpable bogginess or doughiness of synovial membrane, often accompanied by effusion, consider...

synovitis

 

53

joint fluid + tenderness over tendon sheaths, consider

tendinitis

54

Crossover test

Acromioclavicular joint: palpate and compare both joints for swelling or tenderness. Adduct patient's arm across chest. 

Localized tenderness or pain suggests inflammation or arthritis of the acromioclaviular joint

55

Apley scratch test

Rotator cuff d/o or adhesive capsulitis

A image thumb
56

Neer's impingement SIgn

Press on scapula to prevent scapular motion w/one hand and raise patient's arm w/other. This compresses the grater tuberosity of the humerus against the acromion.

Pain --> inflammation or rotator cuff tear

 

A image thumb
57

Hawkin's impingement

Flex patient's shoulder and elbow to 90 degrees w/palm facing down. Then, with one hand on forearm and one on arm, rotate arm internally. This compresses greater tuberosity against coracoacromial ligament.

pain: inflammation or rotator cuff tear

A image thumb
58

Testing Supraspinatus Strength

Empty can test

elevate arms to 90 degrees adn internall rotate arms, w/thumbs pointed down, as if emptying a can. Ask pt to resist you as you place downward  pressure on arms

weakness: possible rotator cuff tear

59

Testing infraspinatus Strength

Ask patient to place arms at side and flex elbows to 90 degrees with thumbs turned up. Provide resistance as patient presses the forearms outward

Weakness: rotator cuff tear, bicipital tendinitis

60

Drop-arm sign

Ask ptient to fully abduct the arm to shoulder level (or up to 90 degrees - not above, then it's deltoid) and lower it slowly. 

If can't hold arm out or control lowering the arm, positive for rotator cuff tear

61

Chronic tophaceous gout - hands

can mimic rheumatoid and osteo-arthritis

BUT, not usually symmetrical like rheumatoid is. And knobby swellings ulcerate and discharge white chalklike urates.
