Q

retracted tear

A

irreparable in setting of younger patient w/ minimal glenohumeral joint arthritis benefit from superior capsular recon

  • complete RC tear
  • retracted tissue
  • loss of elasticity due to scarring
  • muscle atrophy and fatty infilitration

Q

Patient considerations prior to surgery:

A
1- failure of conservative treatment
2- age
3- size of RC tear
4- other medical issues
5- social support
17
Q

Massive Retracted Posterosuperior RC tear ( compress subscap nerve)
deteriation measured in :

A

goutallier

stage 0- normal muscle no fat
stage I- some fatty streaks present
stage II- more muscle than fat
stage III- equal muscle and fat
stage IV- more fat than muscle
18
Q

Psuedoparalysis

A

inability to perform more than 90 degrees of active forward elevation with fully intact passive ROM in absence of neurologic impairment

19
Q

Infraspinatus and Teres Minor

A

Origin: infraspinous fossa of scapula
Insert: greater tuberosity of humerus

20
Q

Infraspinatus RC Strength

A

22%

21
Q

Teres Minor RC strength

A

10%

22
Q

Concavity compression

A

compression of convex humeral head into concave surface of glenoid fossa

23
Q

Force Couple

A

2 or more muscles acting in different directions influence rotation of a joint in a specific direction

24
Q

Last Standard portal is the ____ portal.

A

Lat (lateral portal)

working/viewing portal with in a subacromial space in shoulder

25
Q

Posterior portal is established, surgeon can create ______ portals.

A

Anterior portals, standard portal AI (anteroinferior)

done under direct visualization using spinal needl

26
Q

All Arthroscopic procedures will start from the _____ portal.

A

P (posterior portal)
portal is made blind
gives access to GHJ and subacromial space

27
Q

Most common Arthroscopic portals used are :

Anatomic structure commonly outlines are:

A

P : Posterior, Lat: lateral, A: Anterior

  1. clavicle
  2. acromion
  3. tip of coracoid
28
Q

Lateral decubitus Adv. and Dis.

A

lying on good side, arm above body
ADV- better visibility, less barriers to shoulder accessibility, no increases risk of cerebral perfusion

DIS- inc. risk of traction related injury, difficult conversion to open, non anatomic orientation, difficult reach for ant. portal

29
Q

Beach Chair ADV. and Dis.

A

ADV- ease of exam under anesthesia, easy conversion to open, improved mobility of arm

DIS- potential mechanical blocks, increased obstruction of view, increased risk of hypotension/bradycardia
- causing cerebral ischemia

30
Q

shoulder arthroscopy can be performed in the :

A

beach chair position

lateral decubitus position

31
Q

glenohumeral joint

A

articulation of glenoid fossa of scapula and head of humerus
ball in socket

32
Q

subscapularis

A

origin- subscapular fossa
insert- lesser tuberosity of humerus
RC strength- 53%

33
Q

Supraspinatus

A

origin- supraspinous fossa
insert- greater tuberosity
RC strength- 14%

34
Q

Acromioclavicular ligament

A

stabilized by 3 ligaments:

1) acromioclaviclaur lig.
2) coracoclavicular ligaments
- trapezoid lig
- conoid lig

35
Q

sternoclavicular joint

A

only true attachment of shoulder joint complex to bodys axial skeleton

36
Q

shoulder complex made up of 3 _____ joints.

name joints

A

synovial joints

  • glenohumeral joint
  • acromioclavicular joint
  • sternoclavicular joint
