Elbow Flashcards
Medial epicondyle-
Prominent bony point at distal end of Humerus, on medial side
Medial supracondylar line of Humerus
Running upwards from medial epicondyle, the sharp ridge can be palpated
Lateral epicondyle
At the base of a dimple on the lateral aspect of the elbow
Lateral supracondylar line of Humerus
Running upwards from the lateral epicondyle
Olecranon process
Upper and posterior aspect of the elbow. Forms the point of the elbow in flexion
Olecranon fossa
In relaxed elbow flexion can be felt through triceps tendon
Ulna border (posterior) to ulna styloid
Can palpate posterior border throughout length. Styloid is posterior part at the distal end (medial side of forearm)
Radial head
In a dimple on the posterior aspect of the elbow (particularly in elbow extension) can feel it rotate it when asking pt to supinate/pronate
The common extensor tendon
Lateral epicondyle
The common flexor tendon
Medial epicondyle
Surface marking of elbow joint
2cm below the tip of the medial epicondyle to a point 1cm below the tip of the lateral epicondyle of the humerus. Diagonal line between these 2 points
Surface marking of the cubital fossa
Triangular space bordered laterally by Brachioradialis, medially by Pronator Teres and superiorly by an imaginary line drawn between the two epicondyles of the Humerus
Identify the groove in which the ulnar nerve sits
Groove behind the medial epicondyle (Ulnar nerve is known as the ‘funny bone’ – Humerus)
Identify the Biceps tendon
(best palpated in 20 degrees elbow flexion, resisting elbow flexion) from the biceps insertion draw in:
(medial) median nerve / brachial artery / biceps insertion / radial nerve(lateral)
Check brachial pulse with radial artery
Medial to biceps tendon
