Description
Technical field
The present invention relates to the field of medical instrument technology more particularly to a kind of neck of femur controllable compression micro-wound locking steel plates.
Background technology
Fracture of neck of femur early stage sliding hip screw is fixed since wound is big, and destruction of bone is more, although there is fracture end pressurization,
Pressurization distance cannot control, and be susceptible to excessively pressurization and cause the excessive cripetura of neck of femur, do not used at present, used at present
Near end of thighbone micro-wound locking steel plate have wound it is small, destruction of bone is few, the good advantage of angle stability, but treatment neck of femur or
The relative static conditions of fracture end after being fixed due to locking nail when intertrochanter fracture of femur, after being easy fracture end bone information after surgery
There is fracture gap increase and cause bone nonunion, through retrieval, the patent document of application notification number CN106388923A discloses a kind of stock
Bone neck controllably slides locking and pressurizing steel plate, including:The fixation steel that the shape of mounting surface matches with the anatomical structure of near end of thighbone
Plate；Femoral shaft mounting hole, multiple threaded locked holes and multiple sleeves, the femoral shaft mounting hole are provided on the fixation steel plate
