Deep fascia of the Forearm
• The forearm by extensions of
deep fascia which are called
Med. & Lat. intermuscular
septum and interosseus
membraine divided in to two
compartments ( Anterior &
Posterior ) .

FLEXOR RETINACULUM
Situation
:
Is a strong fibrous band which bridges the anterior
concavity of the carpus
Attachments
:
1. Laterally : Tubercle of scaphoid
Crest of trapezium
2. Medially : Pisiform
Hook of hamat
FLEXOR RETINACULUM

Structures passing superficial to the F. R :
Tendon of palmaris longus, Tendon of flex.carpi ulnaris,
Palmar cutaneus br.of Median nerve, Palmar cutaneus
br.of Ulnar nerve, Ulnar vessels, Ulnar nerve

Structures passing deep to the F. R :
Median nerve, Tendons of Flexor digitorum superficialis,
Tendons of Flexor digitorum profondus, Tendons of
Flexor pollicis longus, Ulnar bursa, Radial bursa
** The tendon of Flexor carpi radialis lies between the retinaculm and its
deep slip, in the groove of trapezium**
Cubital Fossa:
Situation
:
Is the triangular hollow and lying in front of the elbow joint
Boundaries
:
1. Superioly ( Base) : Imaginary line between lat. & med.
Epicondyles of humerus.
2. Laterally: Medial border of Brachioradialis muscle.
3. Medially: Lateral border of Pronator teres muscle.
4. Floor : Brachialis and Supinator muscle.
5. Roof : Skin, Superficial & Deep fascia and Bicipital aponeurosis.
6.
Apex : Overlap of Brachioradialis & Peonator teres muscles.
