other features of the elbow

Question 1

carrying angle

Answer 1

a valgus angle

formed by the intersection of the long axis of the shaft of the humerus and the long axis of the forearm

Question 2

what does carrying angle result in

Answer 2

abduction of the forearm in relation to the humerus with the elbow extended

Question 3

what causes changes to the carrying angle

Answer 3

fracture of the distal humerus

tear of the radial collateral ligament

tear of the ulnar collateral ligament

Question 4

fracture of the distal humerus

Answer 4

carry angle changes

Question 5

tear of the radial collateral ligament

Answer 5

decreased angle

Question 6

tear of the ulnar collateral ligament

Answer 6

increased angle

Question 7

carrying angle in men

Answer 7

5 degrees

Question 8

carrying angle in women

Answer 8

10-15 degrees

Question 9

why is the carrying angle larger in women

Answer 9

d/t having wider pelvis

Question 10

orientation of the humeral condyles

Answer 10

the humeral condyles are angled approximately 45 degrees anterior to the frontal plane

Question 11

why are the humeral condyles positioned the way that they are

Answer 11

permits further flexion ROM

also increased by the presence of hollowing in areas of the humerus

Question 12

orientation of the humeral condyles allow

Answer 12

for more physiologic flexion

radial fossa is anterior and provides room for the radial head

coronoid fossa is anterior and provides room for the coronoid fossa

olecranon process is posterior and provides room for the olecranon for full extension

Question 13

closed-packed position of the elbow

Answer 13

is full elbow extension

Question 14

articular disk at the distal radioulnar joint

Answer 14

triangular fibrocartilage (TFCC)

shaped like a triangle with its base at the ulnar notch of the radius and its apex attached to the ulnar styloid

Question 15

functions of the TFCC

Answer 15

shock absorption

increasing the congruity of the distal radioulnar joint
