Introduction[edit | edit source]
The Cubital Fossa is a triangular-shaped depression, located between the forearm and the arm on the anterior surface of the elbow, with the apex of the triangle pointing distally. It is also known as the “antecubital” because it lies anteriorly to the elbow. It is a space filled with different structures that makes up its content. It has three boundaries/borders, and it also has a floor and a roof [1][2]
Structures/Borders[edit | edit source]
- Apex: Imaginary line connecting the medial and lateral epicondyles
- Medial border - the pronator teres
- Lateral border - the brachioradialis
- The floor - formed by the brachialis and supinator muscles
- The roof - formed by skin and fascia of the the arm and forearm reinforced by bicipital aponeurosis (which is a sheet of tendon-like material that arises from the tendon of the biceps brachii). The bicipital aponeurosis forms a partial protective covering to the median nerve, brachial artery, ulnar artery and radial artery[1][3].
