Problems solved by technology

The dynamic hip screw system will cause further damage to the fracture area, loss of bone mass, and separation of the anterior and posterior fractures, and the stabilization effect is not good; and there is no gap between the compression screw and the sleeve plate, and the acceleration between the fracture fragments cannot be achieved. pressure, which is not conducive to the healing of the fracture; in addition, in the face of fragmentation of the femoral head, the system cannot fix the fractured bone

Abstract

The invention provides an internal fixation system for a femoral intertrochanteric fracture. The internal fixation system comprises a bone fracture plate, wherein the bone fracture plate comprises a near end and a far end, and the near end wraps a greater trochanter and is of a three-dimensional structure. The internal fixation system for the femoral intertrochanteric fracture not only can achieve fixation of coronal plane fractures, but also can achieve fixation of sagittal plane fractures, so the femoral intertrochanteric fracture is fixed in a three-dimensional mode, and the internal fixation system is applicable to fixation of fractures with the intertrochanteric fractures and fractures with a front-back separation phenomenon; and in addition, the internal fixation system is beneficial to fixation of small fracture blocks of fracture parts.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an internal fixation system for femoral intertrochanteric fractures. Background technique [0002] Intertrochanteric fractures, also known as intertrochanteric fractures, are extracapsular fractures. For intertrochanteric fractures, dynamic hip screw systems are often used in the prior art for treatment. The Dynamic Hip System consists of a sleeve plate, lag screws, and compression screws. The specific operation process is as follows: after inserting the lag screw until its length is appropriate, insert the sleeve steel plate; after driving in the sleeve steel plate, screw in a compression screw to fix the sleeve steel plate. For intertrochanteric fractures, the lag screw is limited in the sleeve of the sleeve plate. The cooperation between the sleeve plate and the lag screw is too hard, which reduces the activity of the fracture end, and the fracture end does not move ...
