Epipyramis also knows as os epitriquetrum is an accessory ossicle of the wrist. It is a small pyramidal shaped ossicle seen in the medial intercarpal space between lunate, triquetral, capitate and hamate bones. It is one of the rare accessory ossicles of the wrist and can be mistaken for a fracture or a loose body.
