COMPRESSION HIP SCREW HAVING ADDITIONAL COMPRESSION NUT FOR COMPENSATING LAG SCREW

摘要

The present invention relates to a compression high screw having a compression induction nut for compensating for a delayed screw, comprising a screw portion inserted into the femoral ball head, and a support plate portion fixed to the femur body and supporting the screw portion, the screw portion having a hollow inside A barrel portion formed and coupled to the support plate portion, a delay screw slidably inserted into the hollow of the barrel portion, and a delay screw inserted into the hollow of the barrel portion and screwed with the delay screw, and moving the delay screw by rotation to fracture the femoral head It is characterized in that it comprises a compression screw for providing a pressing force to the region, a compression guide nut member provided between the pressing screw and the delay screw, supported by the barrel, and guiding the fracture site to be compressed by the pressing screw.
