Styloid Process |
|
Attachement- Medial Epicondyle of Humerus to medial sides of coronoid process and olecranon process of ulna |
Medial Colleateral Ligament |
|
Attachement- Proximally on the lateral Epicondyle of humerus and distally on the annular ligament and the lateral side of the ulna |
Lateral Collateral Ligament |
|
Function- Stabilizes the Elbow |
Medial and Lateral Collateral Ligament |
|
Attachment anteriorly and posteriorly to the radial notch of the ulna, encompassing the head of the radius and holding it against the ulna |
Annular Ligament |
|
Broad, flat membrane located between the radius and ulna for the most of their lengths |
Interosseous Membrane |
|
Keeps bones from separating and provides more surface area for attachment of forearm and wrist muscles |
Interosseous Membrane |
|

4 |
Distal Radioulnar Joint |
|
Angle formed by the longitudinal axes of the humerus and forearm |
Carrying Angle |
|
What causing the Carrying Angle |
Occurs because the distal end of the humerus is not level. Medial side is lower than lateral side. As the ulna and radius rotate about the the trochlea and capitulum of humerus they do not do so in a straight line |
|
What is a Normal Carry Angle |
10-15 degrees in Women ~5 degrees in Men |
