the cubital fossa and cubital tunnel

Question 4

what ligament consists of a band of fibers that surrounds the head of the radius?

Answer 4

the annular ligament

Question 5

what structure does the annular ligament surround?

Answer 5

the head of the radius

Question 6

what movement does the annular ligament allow for?

Answer 6

it allows the radial head to rotate

Question 7

what structure does the annular ligament help the radial head remain in contact with?

Answer 7

the radial notch of the ulna

Question 8

what ligament of the elbow stretches from the radial/lateral collateral ligament and attaches above the upper edge of the coronoid fossa, extending to just below the coronoid process?

Answer 8

the anterior ligament

Question 9

where does the anterior ligament of the elbow extend from and attach to?

Answer 9

the anterior ligament extends from the radial/lateral collateral ligament and attaches to the upper edge of the coronoid fossa, extending to just below the coronoid process

Question 10

the anterior ligament is __in nature and function

Answer 10

capsular

Question 11

what does it mean for the anterior ligament to be capsular in both function and nature?

Answer 11

it is a reinforcement of the elbow joint capsule rather than a separate structure inside or outside of the elbow joint capsule

Question 12

what ligament of the elbow joint blends in on each side with the radial/lateral and ulnar/medial collateral ligaments, attaching to the upper portion of the olecranon fossa and just below the olecranon process?

Answer 12

the posterior ligament

Question 13

where does the posterior ligament of the elbow attach?

Answer 13

the upper portion of the olecranon fossa and just below the olecranon process

Question 14

what ligament resembles the anterior ligament of the elbow?

Answer 14

the posterior ligament

Question 15

what ligament of the elbow extends from the lateral epicondyle of the humerus to the lateral border of the olecranon process of the ulna and annular ligament

Answer 15

the radial/lateral collateral ligament

Question 16

where does the radial/lateral collateral ligament extend from and attach?

Answer 16

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

Question 17

what shape is the radial/lateral collateral ligament of the elbow?

Answer 17

fan shaped

Question 18

what motion does the radial/lateral collateral ligament of the elbow prevent?

Answer 18

elbow joint adduction

Question 19

what structure does the radial/lateral collateral ligament of the elbow provide reinforcement for?

Answer 19

the radiohumeral joint articulation

Question 20

what ligament of the elbow runs from the medial epicondyle of the humerus to the proximal portion of the ulna?

Answer 20

the ulnar/medial collateral ligament

Question 21

where does the ulnar/medial collateral ligament of the elbow run from?

Answer 21

the medial epicondyle of the humerus to the proximal portion of the ulna

Question 22

what motion does the ulnar/medial collateral ligament of the elbow prevent?

Answer 22

excessive abduction of the elbow joint

Question 23

what ligament of the elbow allows for rotation of the radial head?

Answer 23

the annular ligament

Question 24

what ligament of the elbow prevents adduction of the elbow joint?

Answer 24

radial/lateral collateral ligament

Question 25

what ligament of the elbow prevents excessive abduction of the elbow joint?

Answer 25

the ulnar/medial collateral ligament

Question 26

how is it that the ulnar and radial collateral ligaments can become stretched, frayed or torn through the stress of repetitive throwing motions such as with pitching in baseball?

Answer 26

the force of the soft tissues becomes greater than the tensile strength of the ligamentous structures, causing microtears that can degenerate, eventually resulting in rupture

Question 27

what type of athletes are treated most for ulnar and radial collateral ligament injuries?

Answer 27

baseball pitchers

Question 28

what other MOI can result in collateral ligament rupture and is often associated with elbow dislocation?

Answer 28

a FOOSH

Question 29

what is the cubital fossa and where is it located?

Answer 29

it is a triangular space located in the anterior elbow

Question 30

what is the cubital fossa bordered by?

Answer 30

brachioradialis pronator teres brachialis a horizontal line passing through the humeral epicondyles

Question 31

what structures does the cubital fossa contain?

Answer 31

biceps brachii tendon median nerve radial nerve median cubital vein brachial artery

Question 32

what nerves does the cubital fossa contain?

Answer 32

median and radial

Question 33

what artery and vein does the cubital fossa contain?

Answer 33

brachial artery median cubital vein

Question 34

what tendon does the cubital fossa contain?

Answer 34

biceps brachii tendon

Question 35

what is the cubital tunnel?

Answer 35

a space formed by: the ulnar/medial collateral ligament flexor carpi ulnaris medial head of the triceps medial epicondyle

Question 36

what nerve runs through the cubital tunnel?

Answer 36

the ulnar nerve

Question 37

with what movement does the cubital tunnel become smallest?

Answer 37

elbow held in full flexion

Question 38

where is the olecranon bursa located?

Answer 38

posterior to the olecranon process

Question 39

why does the olecranon bursa become commonly inflamed with direct trauma to the elbow?

Answer 39

because of its superficial position
