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.
