- Apex: Formed by the meeting point of brachioradials and pronator teres.
- Base: Formed by an imaginary line joining the two epicondyles of humerus.
- Laterally: By the medial border of brachioradialis.
- Medially: By the lateral border of pronator teres.
- Roof: Formed by-
- Superficial fascia
- Deep fascia
- Bicipital aponeurosis
- Floor: By brachialis & supinator muscles.
- Tendon of biceps brachii.
- Terminal part of brachial artery.
- Proximal part of radial & ulnar artery.
- Median nerve.
- Radial nerve.
- Vena comitants of brachial, radial & ulnar arteries.
- Some amount of fat.
The cubital fossa is important for the following reasons:
- Medial cubital vein is often the vein of choice for intravenous injections.
- Blood pressure is universally recorded by auscultating the brachial artery in front of the elbow.
- Anatomy of the cubital fossa is useful in case of fracture of the elbow.
