Elbow Joint

Elbow Anatomy



Medial epicondyle- medial side of

humerus at distal end just above

trochlea.

Elbow Anatomy



Lateral epicondyle- located on lateral

side of distal end above capitulum.

Elbow Anatomy



Capitulum- lateral side of joint, it

articulates with the radius.

Elbow Anatomy



Trochlea- located on the medial side of

the distal end of the humerus.

Articulates with ulna.

Elbow Anatomy

The ulna does not move.

 The radius moves around the ulna.

 The ulna is locked in place by the

proximal end at the olecranon

process.

Elbow Anatomy



Olecranon fossa- posterior surface of

the humerus between the medial and

lateral epicondyles.

Elbow Anatomy



Olecranon process- proximal end of

ulna, on posterior surface. The point

of elbow where triceps attaches.

Elbow Anatomy



Coronoid Process- just below the

trochlear notch and next to the radial

notch. Attachment for brachilis.

Elbow Anatomy



Ulnar head- distal end on the lateral

surface, radial head pronates around

it.

Elbow Anatomy



Radial head- proximal end, where it

articulates with the capitulum.

Elbow Anatomy



Elbow joint- where the radius and ulna

articulate with the humerus.

is a pivot joint.

It allows supination and pronation.

Elbow Ligaments



Medial Collateral Ligament- runs from

medial epicondyle of humerus to the

medial side of coronoid process and

olecranon process.

Elbow Ligaments



Lateral collateral ligament- attaches

proximally to the lateral epicondyle and

distally to the lateral ulna and annular

ligament.

Annular Ligament- encompasses
