摘要

Implant for the reduction and treatment of trochanteric fractures of the femur, which are used to stabilize and allow immediate loading in all types of pertrochanteric fractures, including unstable fractures with great comminution of calcar or anatomo-pathological complexity and other applications of a similar nature, preferably in the neck of the femur and in other fractures of similar character, being composed of a set of two fundamental pieces, one of which is formed by a monoblock nail-plate, and a strut that is joined to the plate -clave, both forming a rigid and indeformable assembly, characterized in that the joining plate (1) has a geometry of variable section and increases in its middle zone where the projection (7) intended to house the strut (10) is located, from where, on the one hand, a progressive section decreases with external radial displacement (5) in the direction of the confluence (11) with the nail (12) where it has a rounding to avoid discomfort due to contact with the skin and in its upper third initiates an internal angular displacement towards the back (6), and on the other hand it initiates a decrease of progressive section in downward direction, being attachable and fixable to the bone (2). ) in a vertical position through several holes (4) of its lower end and by screws (3) of cortical, comprising at its upper end and in solidarity form forming a unitary piece with a tilt of 120º a nail (12) of decreased section progressively towards the tip (19), lodged within the bone itself and oriented towards the neck of the femur (14) to which it is fixed after the fracture point (15), with the nail (12) itself, an axial hole (13) ) through, for its introduction aligned by a previous needle stuck in the bone, which will be removed later.
