Abstract
The utility model relates to a three-dimensional pinning steel plate, which is characterized in that the utility model comprises a steel plate, and an inclined hole, a longitudinal chute, a transverse chute, an ellipsoidal hole, holes with threads or holes without threads, which are arranged on the steel plate. A nail-plate or a pin bone locking is constituted through a cortical lag screw, a solid or a hollow cortical lag screw of a double-line conical screw cap, and a solid or a hollow tail end cortical lag screw, which are positioned in the steel plate, and the nail-plate or the pin bone locking is designed into three types of A type, B type and C type. The utility model can treat proximal and distal femur fracture, femoral intercondylar fracture and femoral supracondylar fracture, and proximal humerus fracture, and solve the shortcomings of caxa vara and genu varum which are caused by the weaknesses of the apparatus design and existed in the process of treating intertrochanteric fracture and femoral supracondylar fracture after operations. The unload systems of femur intertrochanteric and femoral condyle is rebuilt through the triangle intercross combination of the nail needle plates and the three-dimensional non-uniplanar interleave of needle plates, which increases the integral stability of the utility model. The utility model has the advantages of simple operative procedure, small injure, less bleeding, and large global stability, which can be inserted through a minimal invasion incision.
