Joints of the Shoulder Girdle

Where does the joint capsule attach on the sternoclavicular joint

Surrounds the margins of the articular surfaces of clavicle and manubrium.

What are the ligaments of the sternoclavicular joints

Ant/Post SC ligs
Interclavicular
Costoclavicular

What is the function & attachments of the disc in the sternoclavicular joint.

Divides SC into 2 compartments. Attached to ant and post SC ligs and interclavicular ligs.

Describe the capsule of the AC joint

Relativley loose and sleeve like. Attaches to the margins of the articular surfaces.

Name the ligaments of the AC joint and the ligaments that make up the coracoclavicular lig.

AC lig
Coraco-acromial
Conoid & Trapezoid

What are the intracapsular structures of the glenohumeral joint

Glenoid labrum and long head of biceps

Where does the joint capsule of GH attach
Medially:
Laterally:
Sup:

Inf:

Rim of glenoid
Anatomical neck of humerus
Encloses attachment of long head of biceps to supraglenoid tubercle.
Weak, loose and unsupported

What are the ligaments of the GH joint

GH lig
Coracohumeral
Transverse humeral
Coracoacromial

Name the bursae of the GH joint

Subacromial/subdeltoid
Subscapular

Attahchments of the conoid ligament

From the root of coracoid process to the conoid tubercule on inf clavicle.

Attachments of the trapezoid ligament

From sup surface of coracoid process to trapezoid line on inf clavicle.

Attachments of coracohumeral ligament

From coracoid tubercule to ant aspect of greater tubercule.

Attachments of transverse humeral ligament

From greater to less tubercules

Attachments of coracoacromial ligament

From coracoid process to acromion. Forms a protective arch over head of humerus.

What is the vascular supply to GH joint

Ant & post circumflex humeral arteries and subscapular artery.

Describe the position of the subscapular bursae

Between tendon of subscapularis and neck of scapula. Communicates with GH joint.
