THE CUBITAL FOSSA
ROOF OF THE FOSSA:
Antebrachial fascia, subcutaneous tissue, skin
Basilic Vein
CONTENTS OF THE ROOF:
Bicipital aponeurosis
Median cubital vein
Medial cutaneous nerve of forearm
Lateral cutaneous nerve of forearm
Medial cutaneous
antebrachial nerve
SUPERIOR BORDER:
An imaginary line between
the two epicondyles of the
humerus
Cephalic vein
Lateral cutaneous
antebrachial nerve
MEDIAL BORDER:
Pronator Teres
Bicipital aponeurosis
LATERAL BORDER:
Brachioradialis
FLOOR OF THE FOSSA:
Brachialis and Supinator
CONTENTS OF THE FLOOR
Superficial branch of the radial nerve
(as it runs under the brachioradialis)
Deep brach of the radial nerve
Median nerve as it enters the arm
between the heads of pronator teres
Deep Branch of the
radial nerve
Superficial branch of
the radial nerve
Brachial artery
BOUNDARIES:
-
SUPERIORLY: An imaginary line between the medial and lateral epicondyle
LATERALLY: brachioradialis
MEDIALLY: Pronator teres
