SURFACE ANATOMY OF CUBITAL FOSSA,ITS BOUNDRIES,STRUCTURES AND THEIR RELATIONS

1. CUBITAL FOSSA

2. OBJECTIVES: To study the boundaries, the contents and the relationship among structures of cubital fossa. The surface anatomy of the cubital fossa. The clinical importance of the cubital fossa.

3. Introduction Cubital Fossa : A triangular hollow area that lies in front of the elbow joint.

4. Boundaries OF Cubital Fossa Superiorly: An imaginary line connecting medial and lateral epicondyles. Medially: Pronator teres muscle. Laterally: By the brachioradialis muscle.

5. Boundaries OF Cubital Fossa Roof : Deep fascia of forearm forms its roof, strengthened by fibres of bicipital aponeurosis. In superficial fascia are anterior branches of medial and lateral cutaneous nerves of forearm and median cubital vein, which joins cephalic and basilic veins. Bicipital Aponeurosis

6. Boundaries OF Cubital Fossa Floor : Formed of the brachialis medially. Supinator muscle laterally overlying the capsule of the elbow joint.

7. CONTENTS OF CUBITAL FOSSA From medial to lateral are: Median nerve. Brachial artery, its terminal branches, radial and ulnar arteries. Biceps tendon and bicipital aponeurosis . Radial and posterior interosseous nerves, often overlapped by fibres of brachioradialis.

9. Quick Review Of Cubital Fossa

10. CLINICAL ASPECT OF CUBITAL FOSSA Common Site For Venepuncture : Cephalic, basilic and median cubital veins are usually easily seen and palpated in the roof of the fossa, and this is therefore a common site for venepuncture.

11. CLINICAL ASPECT OF CUBITAL FOSSA Variations in venous anatomy at this site are common . Cubital fossa for intravenous fluid therapy is not recommended because movement of the elbow joint disturbs the cannula and irritates the vein wall. Thrombosis of the vein quickly occurs. Patient extending both arms, showing mottling and bluish discoloration of the left arm, compared to the normal right arm.

12. CLINICAL ASPECT OF CUBITAL FOSSA Measure The Blood Pressure: Sphygmomanometer cuff is applied proximal to the base of it and the diaphragm of the stethoscope is placed over it to measure blood pressure.
