Abstract:
Provided are a bone fixation screw apparatus and a fastening method thereof. More particularly, provided are a bone fixation screw apparatus and a fastening method thereof including a bone screw which is inserted to a lower side of a receiving portion and has a spherical head formed at a proximal end, a collect chuck which is inserted to an upper side of the receiving portion to be connected with the spherical head of the bone screw inside the receiving portion, and a rod which is seated on an upper side of the collet chuck and fixed through a fixing screw fastened to the receiving portion, in which the bone screw and the collet chuck are introduced to the receiving portion in opposite directions to each other. Therefore, it is possible to firmly and easily fasten the bone screw and the collet chunk and prevent the bone screw from being easily separated by external force.

Claim (Index 15):
A fastening method of a bone fixation screw comprising steps of:\n inserting a spherical head formed at a proximal end of a bone screw into a lower side of a receiving portion; inserting a collet chuck to an upper side of the receiving portion to connect the spherical head of the bone screw and the collet chuck to each other inside the receiving portion; inserting a plurality of protrusions formed on an outer circumferential surface of the collet chuck into a plurality of restraint grooves formed on an inner circumferential surface of the receiving portion to fix the collet chuck and the bone screw to the receiving portion; and seating a rod on an upper side of the collet chuck and fastening a fixing screw to the inside of the receiving portion to fix the rod.
