Elbow and Forearm

Question 1

Purpose of the Elbow and Forearm

Answer 1

to position the hand in space

Question 2

the joints at the elbow

Answer 2

the humeroulnar joint and the humeroradial joint

Question 3

motions that occur at the humeroulnar joint

Answer 3

flexion and extension

Question 4

motions that occur at the humeroradial joint

Answer 4

pronation and supination
Spin of the radial head, glide of the proximal and distal radio-ulnar joints
interosseous membranes fibers allow spin but not seperation

Question 5

how is the carrying angle formed?

Answer 5

because the medial humeral condyle is longer then the radial which makes the hand go out laterally

Question 6

what is acceptable carrying angle range

Answer 6

5-15 degrees; should check the end feel to see if function is ok

Question 7

ligaments at the elbow

Answer 7

medial collateral (ulnar side)
annular ligaments (radial side)

Question 8

medial collateral ligament (ulnar side)

Answer 8

sprain is most common with a fall onto outstretched hand

Question 9

annular ligaments

Answer 9

contains the radial head while allowing spin to happen

Question 10

stress/ injury at the elbow PT considerations

Answer 10

can live with an elbow flexion contracture. Need to get elbows moving as soon as possible to get proteoglycans and GAGs to function properly and prevent stiffness

Question 11

compensatory motion of pronation

Answer 11

shoulder abduction and internal rotation (need pronation to eat)

Question 12

with an epicondylar fracture

Answer 12

anticipate flexion/extension contractures

Question 13

with a radial head fracture

Answer 13

anticipate pronation and supination problems
