Distally by supinator

4

(Really need beer to be at my nicest)

6

Superior border of cubital fossa

Imaginary line between epicondyles of humerus

7

Clinical relevance of cubital fossa

Venipuncture (median cubital vein),
Measuring blood pressure (korotkoff sounds of brachial pulse),
Supracondylar fractures

8

What 2 veins are connected by the median cubital vein

Basilic
Cephalic

9

What's a Supracondylar fracture and how does it commonly occur

Transverse fracture spanning between 2 epicondyles

Falling on a flexed elbow

10

Clinical relevance of Supracondylar fracture

Displaced fracture fragments (or post fracture swelling) can damage contents of cubital fossa

This can be:

-damage to median or radial nerves
-Loss of blood supply to forearm by brachial artery resulting in volkmann's ischaemic contracture (uncontrolled flexion of hand as flexor muscles become fibrotic and short)
