1
Q
Ligaments of Elbow
A
- Annular ligament of radius
- Collateral ligaments
2
Q
Annular Ligament of Radius
A
- Encircle head of radius
- Pinned on radial notch
- Important for proximal radioulnar joint
3
Q
Collateral Ligament Types
A
- Radial/lateral
- Medial/ulnar
4
Q
Elbow Dislocation
A
- Radius comes off capitulum
- Ulna comes off trochlea
- Slip posteriorly
5
Q
Radial Head Subluxation
A
- Arm jerked upwards
- Forearm pronated
- Annular ligament tear from radial neck attachment
- Radius dislocation
- Annular ligament trapped between radius & humerus
6
Q
Radial Head Repair
A
- Return radius to normal position through movement
- Forearm supination & elbow flexion
7
Q
Cubital Fossa
A
- Triangular shaped region
- Anterior aspect of elbow
- Transition zone from arm to forearm

- Pronator teres
10
Q
Radial Nerve Pathway
A
- In front of lateral epicondyle
- Back around to posterior aspect of forearm
11
Q
Bicipital Aponeurosis
A
- Covers biceps tendon

12
Q
Aponeurosis
A
- Provide protection for brachial artery
13
