nerve supply to ant capsule and GH joint?
Axillary, Suprascapular with Musculocutaneous to the anteriosuperior portion
nerve supply to posterior capsule and GH joint?
Axillary and suprascapular
Anterior blood supply to the shoulder?
Anterior Humeral Circumflex A to subscap, anastomoses w Post Humeral Circumflex A @ biceps tendon
Post Blood supply to shoulder?
suprascapular a and post humeral circumflex
Labral blood supply to shoulder?
suprascapular, post humeral circumflex, circumflex scapular a.
(note ant sup labrum has poor blood supply and inferior labrum has robust blood supply)
GH Congruency?
GH becomes more congruent at higher levels of abduction so contact area increases
IGHL action?
tighten w Abd/ER
SGHL action?
tighten w Add/ER
MGHL action?
tighten w Add/ER
Ratio GH to Scapulothoracic motion in abduction?
generally 2:1 BUT:
first 30 degrees all GH
last 60 from 120-180 ratio 1:1
Nreve complication from Anterior Portal shoulder scope?
MusculoCutaneous Nerve - running 2cm inf and 1cm medial to coracoid
Nerve complicatio from Posterior Inferior Portal shoulder scope?
Axillary nerve - 5 cm below acromion
**With increasing abduction in teh scapular plane, maintaining neitral rotation, contact area, and contact pressure per unti area between the humeral head and glenoid follows what pattern if the total load across the joint is held constant?
Contact area increases and contact pressure decreases.
What ligaments are primary static restraints to inferior translation of the arm when the shoulder is in 0 degrees abduction and neutral rotation?
Superior GlenoHumeral and coracohumeral
Best description of most common anatomic variation in glenoid labrum and MGHL in anterosuperior quadrant of shoulder?
Labrum attached to glenoid rim and a flat/broad MGHL
Atraumatic neuropathy of the suprascapular nerve usually occurs at what anatomic location?
Suprascapular and spinoglenoid notches.
Xray view to detect Bony Bankart?
West Point Axillary
Xray view to detect Hill-Sachs?
Stryker notch
GLAD lesion?
Glenoid Labrum Articular Defect
shoulder brace for non-throwing athletes?
Duke brace
Shoulder brace for throwing athletes?
Sully brace
Evidence conclusions for shoulder stabilization procedures in high energy sports
evidence supports operative fixation.
Bankart lesion and displacement in IR vs ER?
IR is displaced
ER is reduced
Is need for immediate surgery for shoulder instability supported by the literature?
Not at this time.
best position to immobilize arm after shoulder dislocation?
Adduction and External Rotation
17yo linbacker primary ant shoulder dislocation requiring reduction but has no bone or rotator cuff issues - treatment algorithm?
ROM, functional brace, return to play when pain free.
50 yo w primary ant shoulder dis, was reduced then immobilized a few weeks. 3mos postop c/o pain w activity and at night + weakness w overhead activity. Most likely cause?
Axillary nerve palsy (p188)
Acute HAGL Rx?
Open repair of lateral joint capsule disruption. (p188)
When become concerned about Hill Sachs and need for grafting?
25-35%
Hill-Sachs Humeral defect surgical options?
Capsular shift
Glenoid recon-ICBG?Latarjet
Oseoarticular allograft
Arthroplasty
RC "Rimplissage" (arthro place infraspin tendon into defect w suture anchors)
Reverse Hill-Sachs defect/instab surgical options?
LT Transfer (McGlaughlin)
Osteoarticular allograft
Arthroplasty
Arthrosurface HemiCAP
Chronic locked A/P dislocations - when closed red?
up to 4-6 weeks post injury, but then need to do open.
Chronic lockd A/P dislocation surg Rx?
Open red + transfer LT with subscap in young with defects 20-45% of humeral head
Chronic locked A/P dislocation - when hemi?
Only when defect >50-60%
what anatomic item associated with higher rate recurrence after arthro stab?
"Inverted Pear" glenoid deficiency
ALPSA lesion?
Anterior Labral Periosteal Sleeve Avulsion: avulsion of the anterior inferior labrum which heals medially on the scapular periosteum.
Indications for fixation GT fx?
>1cm? (look up)
primary restraint to posterior translation?
Subscapularis
Post subluxation physical finding?
reproducible click and pain with posterior stress or loading
+Kim sign.(Jerk test p 193)
usual path for post instability?
"reverse Bankart"
Post glenoid bone loss surgical options?
glenoid osteotomy
ICBG
acromial bone block
Scapular dyskinesia types?
inf/med
medial
sup/med
Internal Shoulder Impingement?
contact between articular side of the rotator cuff and the posterio-superior glenoid
PE findings for internal impingement?
dec IR
inc ER
+ relocation test
+ O'Brien test (SLAP)
Trhowing injuries?
ant laxity w hyperangulation
PostSup SLAP tears w undersurface cuff injury
GIRD?
Glenohumeral Internal Rotation Deficit
Post/Inf capsule contracture -->
loss of IR
Why PIGHL contracture in throwers?
repetitive overuse
muscular fatigue of RC & Scapular stabilizers
deceleration overloads muscles, caplule responds by hypertrophy
Result of "peel-back" mechanism in throwers?
type II SLAP
Rx symptomatic posterior capsular contractures?
90% respond to capsular stretching
10% need surgical release
Structures at greatest risk for pitcher with pain in early acceleration phase?

benefit glenoid vs humeral based MDI capsulorrhaphies?
equal, dealer's choice
however, one study showed humeral-based best for excessive capsular redundancy
