Claim 0:
1. A fixation device for stabilizing fractured bone portions comprising:
a bone plate having at least one opening;
a housing having a proximal end adapted to be secured to the bone plate, a distal end opposite the proximal end and a bore extending between the proximal and distal ends, the housing defining a length from the proximal end to the distal end along a longitudinal axis and external threading;
a compression screw being at least partially disposed within the bore of the housing and selectively moveable through the bore, the compression screw including external threading; and
a first anchoring member and a second anchoring member coupled to the compression screw and configured to transition between a first condition in which a portion of each of the first anchoring member and the second anchoring member has a first distance from the longitudinal axis and a second condition in which the portion of each of the first anchoring member and the second anchoring member has a second distance from the longitudinal axis by engaging with the external threading of the compression screw, the second distance being greater than the first distance,
wherein the portion of the first anchoring member transitions from the first condition to the second condition to allow the portion of the first anchoring member to engage bone and assist in axially and rotationally securing the fractured bone portions,
wherein the first anchoring member is spaced from the second anchoring member along the longitudinal axis, and
wherein when the first anchoring member and the second anchoring member are transitioned between the first condition and the second condition, the housing maintains its length.
