Hand

Front 1

Name all 8 of the carpal bones from lateral to medial for the proximal ones, and lateral to medial for the distal ones

Back 1

scaphoid, lunate, triquetrum, pisiform (sesamoid),

Hamate, capitate, trapezoid, trapezium

Front 2

Does the head of the ulna articulate with the wrist bones?

Back 2

No, the head of the ulna does not articulte with wrist bones. It has a wedge shaped fibrocartilage disc between it and the bones of the wrist.

Front 3

The radius articulates with what wrist bones?

The articular disc articulates with what bones?

Where is the capsule of the wrist joint attached?

Back 3

Radius - articulates with scaphoid and lunate.

Articular disc with lunate and triquetral

Front 4

What is a colles fracture? ( what can happen to the ulnar?)

How does it differ from a Smith's fracture?

Back 4

Fracture of the distal radius resulting in dorsal displacement of distal radius. Gives dinner fork deformity. Ulnar styloid process may be avulsed.
(caused by a fall on an outstretched hand)

Smith's fracture - anterior displacement of distal end of the radius.

Front 5

Radial artery - branch of what? lies deep to which muscle before then emerging to which side of it? i

At wrist lies lateral to what muscle?

Runs posteriorly to which anatomical structure?

Back 5

Lies deep to brachoradialis. Then emerges medial to brachioradialis, and at wrist lies lateral to the flexor carpi radialis tendon.

Then runs posterior to anatomical snuffbox

Front 6

Ulnar Artery runs beneath which muscles ? passes beneath which muscle with the ulnar nerve. At wrist lies lateral to what muscle?
Gives off a brach called what?

Back 6

Runs beneath pronator teres and flexor digitorum superficialis. passes beneath flexor carpi unlaris with ulnar nerve. At wrist lies lateral to flexor carpi ulnaris. Gives off a common interosseous artery.

Front 7

What is the allen's test?

Back 7

Used to check the palmar anastomes between ulnar and radial arteries.
Used to see wether radial artery is ok to cannulate.

Front 8

What supplies the cutaenous inervation of the lateral and medial sides of the forearm?

Back 8

Lateral cutaneous nerve of forearm is from musculocutaneous nerve continuation.

Medial cutaneous nerve is from brachial plexus Medial Cord.
