Q

Why does the joint capsule have no direct attachment to the radius?

A

To allow movement between the ulna and radius such as pronation and supination

Q

What are the moments that occur at the elbow joint?

A

Flexion and extension

17
Q

When does flexion occur until?

A

Contact between forearm and arm prevents further motion

18
Q

What is the degree of flexion when active?

A

145

19
Q

What is the degree of flexion when passive?

A

160

20
Q

What muscles are involved in flexion?

A

Brachilais, biceps brachii and brachioradialis

21
Q

What limits flexion of the elbow?

A

Apposition of forearm and arm

22
Q

What is the ROM of extension?

A

0

23
Q

Why is the ROM low?

A

Returns back to anatomical position

24
Q

What muscles actively cause extension?

A

Triceps Brachii and aconeus

25
Q

What muscles passively cause extension?

A

Eccentric control of brachilais, biceps brachii and brachioradialis and gravity

26
Q

What is the carrying angle of the elbow joint?

A

The angle between the long axis of the humerus and long axis of the ulna when articulated

27
Q

What causes stability of the elbow joint?

A

Medial and lateral collateral ligaments

28
Q

What angle is greatest stability achieved?

A

90 degrees flexion
