Cubital Fossa  

The Cubital Fossa is important clinically because of

  1. Removal of blood from median cubital vein
  2. Palpation of the brachial artery in blood pressure measurement
  3. Supracondylar fractures of humerus and danger of injury to contents

with the use of an illustration show the contents of the cubital fossa in relation to each other


  • Posterior border of ulna is subcutaneous. The bone can be exposed surgically from end to end without danger

  • When forerarm is flexed against resistance, brachioradialis is prominent along the radial border. The radial pulse is medial to this.

  • The median nerve is deep to palmaris longus tendon therefore cuts anterior to the wrist region may damage any number of these structures

  • The scaphoid bone is papbable in the depth of the anatomical snuff box. Scaphoid fractures present with tenderness in the box

  • Note the tremendous importance of antecubital veins in venesections

  • Radial fractures proximal to the pronator teres may be splinted with the forearm in supination.

  • Radial fractures distal to the pronator teres may be splinted with forarm in neutral position.

  • Stethoscopes are placed on the brachial artery, medial to the tendon of biceps for blood pressure measurements

  • Hand infections may spread proximally into the space of Parona
