1. An intersomatic implantable device comprising:
a. a prismatic body having:
i. substantially planar superior and inferior surfaces, each adapted to engage a superior and inferior vertebrae, respectively;
ii. substantially planar lateral sides; and
iii. substantially planar proximal and distal surfaces;
b. a pair of ducts extending longitudinally from a proximal end to a distal end of the intersomatic implantable device positioned at diagonally opposite vertices of the prismatic body;
c. rotational enclosures formed at proximal end of the intersomatic implantable device;
d. disengageable shafts having proximal and distal ends, disposed within the ducts, and defining stowable mobile components;
e. flaps operably attached to the proximal ends of the shafts and positioned within the rotational enclosures; and
f. wherein the flaps are configured to rotatably interact with the superior and inferior vertebrae, each flap establishing a single point of contact to facilitate distraction of the superior and inferior vertebrae when rotated in a first direction, and to secure the intersomatic implantable device at an implantation site when rotated in an opposite direction.
