Anatomy The anterior limit of the Iliac crest of the ala of the ilium, separated by a notch from the anterior inferior iliac spine. Vignette Easily felt and located, useful surface anatomy landmark; McBurney’s point (where deep tenderness can indicate acute appendicitis) is 2/3 distance from umbilicus to anterior superior iliac spine.

Anatomy Common fracture site (much more so than anatomical neck), with risk of damage to adjacent axillary nerve. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy The articular surface of the bottom of humerus is divided into trochlea medially (for trochlear notch of ulna, which is between coronoid process and olecranon) and capitulum laterally (for head of radius). Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Just above the trochlea (which articulates with head of ulna) at bottom of humerus medially. When the arm is bent (ie elbow hinge joint flexed), the coronoid process of ulna sits in the coronoid fossa (limiting further flexion).

Anatomy Swelling lateral to humeral head, above and behind lesser tubercle. Attachments; supraspinatus, infraspinatus, teres minor. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Rounded upper extremity of humerus; articulates with scapula at glenoid cavity/fossa. Vignette Shoulder is most mobile joint; flexion 150-170°, extension 40°, abduction 160-180°, adduction 30-40°, lateral rotation (in abduction) 95° (in adduction) 70°; medial rotation (in abduction) 40-50° (in adduction) 70°.

Anatomy Groove between greater and lesser tubercles, running down upper 1/3 of shaft of humerus. Attachment; long tendon latissimus dorsi (teres major attached medially, pectoralis major laterally). Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Bump at bottom of humerus, laterally (when hand pronated, ie palm forward). Attached; radial collateral ligament (contributes to stabilizing the joint against varus – medial flexion), supinator, extensors. Smaller than medial epicondyle. Clinical Site of tennis elbow. Supercondylar fractures common in children; anterior displacement of upper part of fracture (proximal fragment) can damage brachial

Anatomy Swelling below and medial to humeral head, below and in front of greater tubercle. Attachment; subscapularis. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Bump at bottom of humerus, medially (when hand pronated, ie palm forward). Attached; ulnar collateral ligament of elbow (significant in stabilizing the joint against valgus – lateral flexion), pronator teres, common flexor tendon. Bigger than lateral epicondyle. Clinical “Funny bone”; ulnar nerve runs just behind it (and can be easily felt – cordlike), with
