Q

What is the clinical relevance of palpating the clavicle

A

Clavicle is the most commonly fractured bone in the body.

It usually fractures at mid-third where it transitions from anterior convexity to posterior concavity.

Clinical Significance: anterior joint line (of GH joint)

Q

SAD

A

subacromial decompression

The most common shoulder surgery

21
Q

Physis

A
  • GROWTH plate
  • Specialized cartilaginous tissue interposed b/w metaphysis & Epiphysis in LONG bones in children
  • Provides GROWTH in LENGTH of long bone
22
Q

physis

A

GROWTH plate Specialized cartilaginous tissue interposed b/w metaphysis & Epiphysis in LONG bones in children Provides GROWTH in LENGTH of long bone

23
Q

What is the clinical significance of the suprasternal notch?

A

there is none

24
Q

where is the anterior (GH) joint line

A

from coracoid process to the inferior axillary fold

25
Q

Anterior Impingement syndrome

A

where the subscapularis get’s compressed against the coracoid process. I think it is also called coracoid impingement syndrome.

Could show up when palpating the coracoid process.

26
Q

coracoid impingement syndrome

A

probably the same as anterior impingement syndrome.

Subscapularis gets compressed against the coracoid process.

27
Q

what structure(s) can be palpated by moving fingers off the anteriolateral edge of the acromion onto the humeral head?

A

superior facet of the greater tubercle of the humerus (supraspinatus tendon).

If you slide fingers posteriorally, you should feel middle and inferior facet, where conjoined tendons of infraspinatus and teres minor attach.

28
Q

Which tendon is most often involved in RCT? Which is the second?

A
  1. Supraspinatous tendon
  2. Infraspinatus tendon
29
Q

When palpating, should the transition from superior to middle facet of the greater tubercle of the humerus jump out at you?

A

No! it is very subtle

30
Q

What will you find about 1.5 - 2 body inches of the anterior (and lateral?) side of the acromion?

A

The Bicipital Groove and Transverse Humeral Ligament (THL) that covers it.

31
Q

What is the clinical significance of palpating the long head biceps tendon?

A

the biceps is a common problem when you have impingement issues

32
Q

Tendinopathy

A

The term tendinopathy is a generic descriptor of the clinical conditions ( both pain and pathological characteristics) associated with overuse in and around tendons

33
Q

What 2 things might be involved/considered after finding pain over LHB tendon in bicipital groove upon palpation?

A
  1. Tendinopathy
  2. Tenodesis
34
Q

tenodesis

A

the surgical suturing of the end of a tendon to a bone. In the LH biceps tendon it is attached to the bicipital groove

35
Q

What is the clinical significance of the soft spot palpable just below the posterior lateral portion of the acromion?

A

it is where a lot of subacromial injections are done

it is a posterior arthroscipic portal site.

it is where internal impingement most commonly occurs.

For us it is a landmark

36
Q

What is the clinical significance of palpating the superior angle of the scapula?

A
  • Levator scapula attaches here
  • Referral from C-spine (called something that sounds like flower sign)
  • Rule out fractures
37
Q

What is the clinical significance of palpating the medial border of the scapula?

A

check for pain and if something might be going on

38
Q

Clinical significance for palpating axillary border of the scapula

A

Axillary border can be fractured, but it is not very common

39
Q

Is it common for the SC joint to get injured?

A

No

40
Q

What is the most common injury seen in SC joint and which population is it found in?

A

anterior subluxation in wrestlers

41
Q

SC joint posterior subluxation

A

VERY SERIOUS because of underlying structures (trachea & carotid artery)

Also very rare!

42
Q

What is the most common problem in AC joint?

A

AC sprain

43
Q

Characteristics of AC sprain or AC problems?

A

Think of Ron (a class of 2017 classmate with this condition)

  • Asymmetry(looks like clavicle is riding up, but really scapula is dropping down)
  • AC OA is common
  • AC DJD is common in older people
  • AC osteolitis is another problem that we may find
44
Q

OA is

A

Osteoarthritis

45
Q

RA is

A

Rheumatoid arthritis

46
Q

osteolysis

A

active resorption of bone matrix by osteoclasts.

Sometimes found in weight lifters

47
Q

GH joint ligaments to palpate

A
  • Anterior capsule
  • Posterior capsule
  • Transverse humeral ligament (over LHB tendon)
48
Q

CA ligament

A
  • it is the Coracoacromial ligament. Find between coracoid process and anterior edge of acromium.
  • Doesn’t jump out of you
  • Small fibrous band
  • palpate inferior to superior
  • one of the most vital ligaments in regards to impingement
49
Q

What is the most vital ligament in subacromial impingment?

A

CA ligament (Coracoacromial ligament)
