Embodiment Construction

[0018] In order to understand the technical solution of the present invention in more detail, the present invention will be specifically described below in conjunction with the accompanying drawings.

[0019] figure 1 , 2 The integrated intramedullary nail system for treating proximal femoral fractures of the present invention is shown, and the system includes a main nail 1 , an integrated head screw 2 , a first supporting screw 3 , a second supporting screw 4 and a slide 5 . Main nail 1 is preferably made of titanium, and it comprises three parts of proximal part 11, transition part 12 and distal part 13, and proximal part 11 and distal part 13 are suitable for inserting femoral proximal end and femoral shaft respectively, and in order to adapt to In the anatomical shape of the femur, the axis of the proximal part 11 and the axis of the distal part 13 form an angle α of about 175-176°, and the transition part 12 makes a natural transition between the two.

Abstract

The invention discloses an integrated intramedullary nail system for treating proximal femoral fracture. The system comprises a main nail (1), an integrated head screw (2), a first supporting screw (3), a second supporting screw (4) and a slip sheet (5), wherein the main nail (1) is made of titanium and consists of a proximal part (11), a transition part (12) and a distal part (13). The novel integrated intramedullary nail system can effectively prevent rotation displacement at the post-operation fracture alignment part and collapse at the fracture end so as to reduce the possibility of related post-operation complications.

Description

technical field [0001] The invention relates to equipment for orthopedic surgery, in particular to intramedullary fixation equipment for femoral intertrochanteric fractures, in particular to an integrated intramedullary nail system for treating proximal femoral fractures. Background technique [0002] With the aging of the population, the incidence of intertrochanteric fractures is increasing. Intramedullary fixation is more and more widely used in the treatment of intertrochanteric fractures because of its biomechanical advantages. However, intramedullary nail-related complications such as femoral head-neck rotation, head screw cutting, femoral neck shortening, femoral head-neck collapse and varus, and femoral shaft fractures also follow. After the development of several generations of intramedullary fixation devices, the incidence of femoral shaft fractures has been greatly reduced by changing the valgus angle of the main nail to adapt to the normal physiological curvatur...
