Elbow Exam Flashcards
What are the bones and joints involved in the elbow
Humerus
Ulna
Radius
Humeroulnar joint
Humeroradial joint
Proximal radioulnar joint
What nerves are at risk in the arm
The radial nerve - tracks along the back of the humerus (risk of injury during mid shaft fracture)
The ulna nerve - runs behind the medial epicondyle (funny bone)
What muscles attach to the medial epicondyle
Pronator teres
flexors of the anterior forearm
What muscles attach onto the lateral epidcondyle
Supinator
Common extensors of the elbow/wrist
What are the ligaments attached to the elbow
Radial collateral ligament
Ulnar collateral ligament
Anular ligament
Where are the bursa in the elbow
Deep (subtendinous) olecranon bursa
Intratendinous olecranon bursa
Superficial (subcutaneous) olecranon bursa
What do you look for in general inspection of the elbow
front
Side
Behind
front, side and back:
Scars
Swelling
Erythema
Side:
fixed flexion deformities
Behind:
Rheumatoid Nodules - firm lumps under the skin
Psoriatic Plaques - Dry skin lesions (plaques) covered in scales
What is the normal carrying angle
Men: 5-15 degrees
Women: 10-25 degrees
What is normal ROM of elbow flexion
145 degrees
What is normal ROM of elbow extension
0 degrees
What is normal ROM of pronation
85 degrees
What is normal ROM of supination
90 degrees
What does wrist flexion against resistance highlight
Medial epicondylitis (Golfer’s elbow)
What does wrist extension against resistance highlight
Lateral epicondylitis (Tennis elbow)
What does an abnormal carrying angle indicate
Increased angle = Cubitus Valgus
Decreased angle = Cubitus Varus
