Trochlea (medial)

Question 21

What are the three fossas located above the capitulum and trochlea

Answer 21

Answer 26

The collateral ligaments; the radial collateral ligaments and the ulnar collateral ligament

Question 27

What is pulled elbow?

Answer 27

When you disarticulate the radius from the annular ligament (ligament that wraps around the head of the radius)

Question 28

Name two olecranon bursae

Answer 28

• Deep intratendinous bursa

- Superficial subcutaneous bursa

Question 29
