*The '''distal sesamoidean (impar) ligament''' originates from the distal margin of the navicular bone and deep digital flexor tendon. It extends from the navicular bone proximally for 1.0-1.5cm and distally to the insertion of the deep digital flexor tendon on the distal phalanx (pedal bone). | *The '''distal sesamoidean (impar) ligament''' originates from the distal margin of the navicular bone and deep digital flexor tendon.
