The Cubital Fossa

• This is a triangular hollow area on the anterior surface of the elbow.
• It is bound superiorly by an imaginary line connecting the epicondyles of the humerus, medially by the pronator teres muscle, and laterally by the brachioradialis muscle.
• The floor of the cubital fossa is formed by the brachialis and supinator muscles.
• The roof of the cubital fossa is formed by deep fascia and includes the bicipital aponeurosis. The roof is covered by superficial fascia and skin.

• This fossa is an important clinical area because it contains the biceps tendon, the brachial artery and its terminal branches (radial and ulnar arteries), the brachial veins, and part of the median and radial nerves.
