GLENOHUMERAL Flashcards
The GH joint is intracapsular or extracapsular?
Intracapsular
How much of a sphere does the humeral head measure?
1/3
What are the possible structure that may be affected when the surgical neck is fractured?
axillary nerve
What does the axillary nerve supply
teres minor &
deltoids
Other name for axillary nerve
circumflex nerve
If the axillary nerve is damaged, which mm/s will you assess to confirm suspicion of damage of the axillary nerve?
Deltoids
Why is the deltoid mm assessed to confirm axillary nerve damage?
As teres minor is difficult to isolate
This is the structure of the proximal humerus that is most prone to fx
surgical neck
This is a sign for (+) deltoid weakness
swallow tail sign
Where does the shoulder jt capsule attaches or inserts?
anatomical neck
What motion of the SH will you ask the pt to do to be able to palpate for the greater tuberosity
ask patient to perform IR of SH
In the aspect of imaging, the greater tuberosity is best viewed in ER or IR
ER
Where can you locate the greater tuberosity?
lateral side of the proximal humerus
Which muscle attaches to the lesser tuberosity?
subscapularis
What motion of the SH will you ask the pt to do to be able to palpate for the greater tuberosity
ask patient to perform ER of SH
What are the muscles that attaches to the greater tuberosity?
SIT muscles
Where can you locate the greater tuberosity?
medial side of the proximal humerus
This is the orientation of the humeral head
MPS (med, post, sup)
This is the groove seen in between 2 tuberosities where the biceps tendon passes through
Bicipital / Intertubercular groove
This ligament anchors the tendon of the long head of biceps along the Bicipital / Intertubercular groove
Transverse humeral ligament
What is the structure that passes through the Bicipital / Intertubercular groove
Tendon of long head of biceps
This is the groove wherein the Radial / musculospiral n. passes
through
Spiral / radial groove
This special test is done to assess tear in the transverse humeral ligament
yergason’s test
Groove located posteriorly at the humerus
Spiral / radial groove
Part of the humeral shaft that is a site for fx
Spiral / radial groove
What is the only muscle that is spared if there is a radial nerve damage?
long head of triceps because it is innervated by axillary nerve
GH joint is what type of joint?
Synovial ball & socket / universal / spheroidal
ligament that limits excessive ER & inf/downward
translation of humerus
coracohumeral lig.
muscle that limits excessive ER & inf/downward
translation of humerus
supraspinatus
Capsular pattern of frozen shoulder
ERABIR
comorbidity associated with a risk for frozen sh
diabetes mellitus
ligament that limits excessive ER
GH & coracohumeral lig
This is the foramen seen in between the superior and middle GH lig
foramen of weitbrecht
This is the foramen seen in between the inferior and middle GH lig
foramen of Rouvier
laxity or tear of the GH ligament may result to what condition?
anteroinferior SH D/L
What are the boundaries of the bicipital groove
Medial: T. Major
Lateral: Pecs Major
Floor: Lat. Dorsi
