Boundaries of the Carpal Tunnel
- Roof: Flexor retinaculum.
- Floor: Carpal bones (hamate, capitate, trapezoid, trapezium, pisiform, triquetrum, lunate, and scaphoid).
- Medial Boundary: Pisiform and hamate bones.
- Lateral Boundary: Scaphoid and trapezium bones.
Attachments of the Flexor retinaculum
- Medially: It attaches to the pisiform and the hook of the hamate.
- Laterally: It attaches to the scaphoid tubercle and the trapezium.
