Pisiform bone

  • E Trapezium ( trapezium )
  • 1 spoke ( radius) 2 Elle ( ulna ) 3 metacarpal bones ( metacarpals )

The roundish pisiform (Latin pisiform, also the accessory carpal bone of " additional carpal bones ") is the smallest of the eight carpal bones of vertebrates and belongs to the proximal ( proximal ) number of these short bones.

It is located at the side (lateral ) and distally ( distal) of the ulna ( ulna ). At the proximal end of the little finger, the pisiform bone is easily felt from the outside through the skin and in the rotational movements of the forearm ( pronation and supination ), it can be on the triangular bone (os triquetrum ), with which it is obvious back ( dorsal) forms a pivotal connection move back and forth. The pisiform bone is embedded in the tendon of the flexor carpi ulnaris and thus belongs to the so-called sesamoids.
