Device for rotational Stabilization of bone segments as the Head of the femur, formed by a lag Screw,A Side Plate with a Cylindrical portion which receives the internal Orifice with lag screw and a Clamping collar with interior Profile profile to join the chamfering chamfering Screw tIrafondo.

摘要

The present Invention relates to a device for rotational Stabilization of bone segments comprising a plate of bone, a Bone lag and a collar Clamp.The lag of bone To Bone has a coupling End, a distal End, and a Profile of cross-section enchacvetado,At the end of the bone where coupling is configured to engage a first bone segment.A Bone or a Flat portion for coupling to a Second Bone segment and a Cylindrical portion which has a hole for receiving the Inner Slide Way lag.The Clamping collar has a Profile which is engaged with the internal keying keying in cross-sectional Profile of lag when the lag Screw is inserted through the Clamping collarOn an external surface and configured and dimensioned for the free Rotation.In a first position within the internal Orifice of the Cylindrical portion of the bone Plate friccionalmente coupled in a second position.The Internal Hole of the Cylindrical portion of the bone plate to resist or avoid the rotation of the collar on the plate of bone,And so to resist or prevent the rotation of the lag with respect to the bone Plate.
