An intramedullary bone fixation device suitable for treatment of fractures of the tubular bones of the hand or feet. The implantable device can be used singly or introduced through both the radial and ulnar aspects. The device includes a stem having a tip portion at one end and a base member at the opposite end of the stem. The stem and tip portions are configured with a unique configuration and cross section to facilitate insertion into and through the canal and provide the necessary forces on the stem portion within the canal. The base is sized and configured to minimize tissue damage while as the same time providing a strong point of fixation.
