Sternoclavicular, Acromioclavicular, Shoulder, Elbow & Proximal Radioulnar Joints Flashcards
What type of joint is the sternoclavicular joint?
- Pivot
- Ball and Socket
- Saddle
- Planar
Saddle. The rounded convex medial end of the clavicle fits into the concavity on the manubrium
Which of the following is not a ligament that stabilizes and prevents excessive movements of the sternoclavicular joint?
- Supraclavicular ligament
- Sternoclavicular ligament
- Interclavicular ligament
- Costoclavicular ligament
Supraclavicular ligament
Which ligament of the sternoclavicular joint can a branch of the brachial plexus be caught under, causing pain and muscle weakness?
- Supraclavicular ligament
- Sternoclavicular ligament
- Interclavicular ligament
- Costoclavicular ligament
Costoclavicular ligament. Dislocations of this joint are not common but posterior dislocation can result in damage to the brachiocephalic veins that are located posterior to it.
Which of the following is not an innervation of the sternoclavicular joint?
- Nerve to the subclavius
- Supraclavicular
- Brachiocephalic
Brachiocephalic . The blood supply to this joint are the suprascapular and internal thoracic arteries.
What type of joint is the acromioclavicular joint?
- Pivot
- Ball and Socket
- Saddle
- Planar
Planar. The main function of the joint is to bind the clavicle to the scapula in order to support the weight of the upper limb and keep the humerus suspended at the side. Shoulder separation occurs at this joint
Which of the following is not a ligament that stabilizes the acromioclavicular joint?
- Acromioclavicular ligament
- Coracoclavicular Ligament
- Sternoclavicular ligament
Sternoclavicular ligament
Which one is not an innervation of the acromioclavicular ligament?
- Suprascapular nerve
- Subclavian nerve
- Lateral Pectoral nerve
Subclavian nerve. The blood supply include the suprascapular artery and the thoracoacromial trunk
Which of the following is not a ligament for the glenohumeral joint?
- Coracoacromial ligement
- Coracohumeral ligament
- Transverse Humeral Ligament
- Glenohumeral ligament
- Sternoclavicular ligament
Sternoclavicular ligament. The glenohumeral ligament has a superior, middle, and inferior portion.
What does the superior portion of the glenoid labrum include?
The supraglenoid tubercle and the origin of the tendon of the long head of the bicpes.
The shoulder of the capsule attaches to:
- The anatomical neck of the humerus
- The surgical neck of the humerus
The surgical neck of the humerus
Aside from the rotator cuff muscles, which other muscle strengthens the capsule of the shoulder joint
Long Head of the Biceps Brachii
Which of the following is not an opening for the capsule of the shoulder joint?
- Between the greater and lesser tubercles that allows passage long head of the biceps brachii through the shoulder joint
- At the inferior angle of the subscapularis
- below and anterior to the coracoid process
- Posteriorly between the joint and a bursa under the infraspinatus tendon
At the inferior angle of the subscapularis
The subacromial/ subdeltoid is_____to the supraspinatus
- Superficial
- Posterior
Superficial. It normally does not communicate with the glenohumeral joint
Which of the following is not an inervation of the glenohumeral joint?
- Suprascapular Nerve
- Axillary Nerve
- Lateral Pectoral
- Posterior Cord of the Brachial Plexus
- Internal Thoracic Nerve
Internal Thoracic Nerve
The rotator cuff muscles involve ______stability for the Glenohumeral Joint
- Active
- Passive
Passive
The rotator cuff muscles pull the head of the humerus:
- Upward
- Downward
Downward.
For shoulder impingement, pain will be present between what angles of abduction?
60 to 120
Which can test reveals that the supraspiantus tendon has been affected?
- Full Can Test
- Empty Can Test
Empty Can Test
How many bursa are assoicated with the olecranon?
2: One subcutaneous, one deep to the tendon of the triceps
There is an anastomotic connection between what 2 arteries in the elbow joint?
Radial and Ulnar. Other blood supplies in this region include brachial and deep brachial artery
Which ligament is associated with the proximal radioulnar joint?
Annular
What are the main movements of the proximal radial ulnar joint?
Pronation and Supination
