Q

What does the annular ligament surround?

A

The head of the radius

17
Q

What is the purpose of the annular ligament?

A

It allows the head of the radius to rotate and retain contact wit the radial notch of the ulna

18
Q

Where does the anterior ligament of the elbow attach?

A

Stretches from the radial collateral ligament and attaches above the upper edge of the Coronado fossa, extending just below the coronoid process

19
Q

Where is the cubical fossa located?

A

Triangular space located at the anterior elbow

20
Q

What is the cubical fossa bordered by?

A
  1. Brachioradialis
  2. Pronator teres
  3. Brachialis
  4. Horizontal line passing through the humeral epicondyles
21
Q

What does the cubital fossa contain?

A
  1. Biceps Brachii tendon
  2. Median nerve
  3. Radial nerve
  4. Brachial artery
  5. Median cubital vein
22
Q

What is the cubital tunnel?

A

Space formed by the:

  1. ulnar collateral ligament
  2. Flexor Capri ulnaris
  3. Medial head of the triceps
  4. Medial epicondyle
23
Q

What nerve runs through the cubital tunnel?

A

The ulnar nerve

24
Q

When does the cubital tunnel become the smallest?

A

When the elbow is in full flexion

25
Q

Where is the olecranon bursa located?

A

Lies posterior to the olecranon process and is considered the main bursa in the elbow

26
Q

When does the olecranon typically become inflamed?

A

With direct trauma to the elbow due to its superficial position

27
Q

Where is the posterior ligament of the elbow located?

A

Blends on each side with the collateral ligaments and is attached to the upper position of the olecranon fossa, just below the olecranon process

28
Q

Where is the radial collateral ligament (lateral collateral ligament) located?

A

Extends from the lateral epicondyle of the humerus to the lateral border and olecranon process of the ulna and to the annular ligament

29
Q

What is the purpose of the RCL (LCL) ligament?

A

It is fan-shaped and prevents adduction of the elbow joint + provides reinforcement of the radiohumeral articulation

30
Q

Where is the Ulnar Collateral Ligament (Medial collateral ligament) located?

A

Runs from the medial epicondyle of the humerus to the Proximal portion of the ulna

31
Q

What is the purpose of the UCL (MCL)?

A

Prevents excessive abduction of the elbow joint

32
Q

What athlete is most likely to present with an injury to the LCL and MCL of the elbow?

A

Baseball players—ligaments become frayed or torn through the stress of repetitive throwing motions

FOOSH can also rupture collateral ligaments which is often associated with elbow dislocation
