The cubital fossa is a triangular depression located on the anterior aspect of the elbow joint, often referred to as the antecubital fossa or elbow pit. It serves as a key transitional region between the arm and the forearm, through which major neurovascular structures pass. The cubital (anticubital) fossa is a triangular-shaped depression over the anterior aspect of the elbow joint. It represents an area of transition between the anatomical arm and the forearm, and conveys several important structures between these two areas. The 4 main structures of the cubital fossa (from lateral to medial) are the radial nerve, tendon of the biceps brachii muscle, brachial artery, and median nerve. Introduction 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].
