6. FLEXOR RETINACULUM AND CARPAL TUNNEL

7. Definition:

Attachement:-
Lat: scaphoid tubercle,trapezium crest.
Med: pisiform, hamate hook.
Structures passing superficial:-
1) Ulnar N.
2) Ulnar A.
3) Palmis longus.

8. Structures passing deep:
1) Flexor digitorum superficialis.
2) Flexer digitorum profundus.
3) Median N.
4) Flexor pollicis longus.
5) Flexor carpi radialis (in special compartement).
Applied anatomy: Carpal tunnel syndrome: compression of median N in carpal tunnel (usually due to carpal bone dislocation, inflammation of tendons or overstreched hand).
