Ppt on cubital fossa. Very important topic

1. Cubital Fossa Kushagra Batra ( 220101005 ), FMHS, SGT University, Gurugram

2. Competency Identify and describe boundaries & contents of cubital fossa Enumerate the structures forming its roof Name the muscles forming floor of the fossa Name the branches of brachial artery in the fossa Enumerate the clinical importance of cubital fossa

3. Boundaries Laterally – Medial border of brachioradialis Medially – Lateral border of pronator teres Base – Directed upwards It is an imaginary line joining the front of the 2 epicondyles of the humerus Base of cubital fossa Brachioradialis Cubital fossa Pronator teres Apex

4. Roof Superficially to deep, it is formed by: Skin 2. Medial & lateral cutaneous nerves of the forearm 1. Medial cubital vein connecting cephalic & basilic veins Deep fascia, strengthened by bicipital aponeurosis Superficial fascia containing: Medial cubital vein Medial and lateral cutaneous nerves of the forearm Bicipital aponeurosis

5. Fl oor Anterior view Cross sectional view Brachialis Brachialis Supinator Supinator

6. The cubital fossa is actually a narrow space. Therefore, its contents are visible only if the elbow is flexed & the margins are pulled apart Contents Medially to laterally, its contents are: Median nerve It leaves the fossa by passing between the two heads of pronator teres Contents of cubital fossa Median nerve

7. Contents Contents of cubital fossa Median nerve Brachial artery It terminates in the fossa at the level of neck of radius by dividing into radial & ulnar arteries The radial artery is superficial & leaves the fossa at the apex The ulnar artery is deep & passes deep to the pronator teres Brachial artery

8. Contents Contents of cubital fossa Median nerve Brachial artery Biceps tendon It passes backwards and laterally to be attached on the radial tuberosity Biceps tendon

9. Contents Contents of cubital fossa Median nerve Brachial artery Biceps tendon Radial nerve It lies in the gap between brachialis medially & brachioradialis laterally At the level of lateral epicondyle, it divides into two terminal branches: Superficial radial nerve (passes downwards under the cover of brachioradialis ) Deep ulnar nerve (disappears into the substance of supinator) Radial nerve

10. Clinical Anatomy The median cubital vein is often the vein of choice for intravenous injections . It is used for introducing cardiac catheters to get sample of blood from various chambers of heart.

11. Clinical Anatomy The blood pressure is universally recorded by auscultating the brachial artery in front of the elbow

12. Clinical Anatomy Supracondylar fracture of humerus The anatomy of the cubital fossa is important while dealing with fractures and dislocations around the elbow as shown. Fractures of the radial head and neck

13. Clinical Anatomy Elbow dislocations
