One of the most mobile segment of the body

Mobility is provided by how many moving areas

Only connection to the axial skeleton

Provided by the shoulder muscles

Most stable because of the muscles

Rotator cuff

SC joint

Bone to bone

Sternoclavicular joint

Acromioclavicular joint

Glenohumeral joint

No bone to bone

Bicipital groove

Subacromial joint

Scapulothoracic joint

Long, slender bone that lies horizontally at the base/root of the neck

True about clavicle, except:

Clavicle correct orientation

Most commonly fractured bone

If there is a complete clavicular fracture: Medial fragment

If there is a complete clavicular fracture: Lateral fragment

Space between the clavicle and first rib

Contents of costoclavicular space

Also known as shoulder blade

Flat triangular bone that lies on the posterior chest wall between the 2nd and 7th ribs

Landmarks of scapula

Summit of the shoulder

Orientation of acromion process

Types of acromion process

Orientation of coracoid process

Most common type of acromion process

Most common type in impingement syndrome

What prevents superior translation of the humerus?

Painful arc: Tear or dislocation

GH painful arc

Impingement syndrome

Tendinitis

Painless

AC joint is affected

Extension of the acromion process medially

Shallow depression

Above spine of scapula

Below the spine of scapula

Anterior to spine of scapula

Glenoid labrum enhances the depth of the fossa by

Its purpose if tot provide stability and shock absorption within the joint

Parts of humerus

Forms 1/3 of a sphere

end attachment of capsule

Prone to fracture

Nerve usually damaged: Axillary/circumflex nerve

Shallow tail sign

Shallow tails sign

Greater tuberosity is located

Lesser tuberosity is located

Greater tuberosity can be palpated with

Lessed tuberosity can be palpated with

Muscle attachment for greater tuberosity

Lesser tuberosity muscle attachment

Where the long head of biceps brachii tendon passes

Where the radial nerve/musculospiral nerve

This contains the long head of the biceps within the bicipital groove

Special test for THL rupture

AKA intertubercular groove

AKAA radial groove

Articulation of AC joint

Types of AC ligament

Types of coracoclavicular ligament

Prevents superior translation of clavicle (secondary)

Prevents inferior translation of clavicle

Prevents superior translation of clavicle (primary)

Prevents medial displacement of scapula

True about conoid ligament, except

Select what applied for trapezoid ligament

AC joint kinematics

Horizontal curvature of thorax

Vertical curvature of thorax

What type of joint is GH joint?

Articulation of GH joint

Humeral head articulation

Glenoid head articulation

Formed by axis of humeral head, neck and axis of humeral shaft

Formed by axis of humeral head, neck and axis of humeral condyles

Angle of inclination

Angle of Torsion

Ligaments of GH joint

Accessory structure of GH joint

Kinematics of GH joint

Greatly involved in frozen shoulder/adhesive capsulitis

Foramen between superior and middle GH
