Description
Technical field
The present invention relates to technical field of medical equipment, more particularly, to a kind of mating tension band system of proximal femoral nail
System.
Background technology
Fixation is chiefly used in long bone (such as stock, the upper arm, ruler, shin, radius) shaft fracture in intramedullary needle.Its advantage is:In marrow
Needle is more solid firm in itself, and the postoperative early ambulant for or without outer fixation, being conducive to hinder limb that can lack is taken exercise;Skin incision
Smaller, periosteum stripping is limited in scope, and damage is smaller;Intramedullary needle is long and has different shape corner angle, and embedded pulp cavity, it is firm to reach
Interior fixation, rotation, the generation of sidesway and angulation displacement can be avoided.
Applicants have discovered that at least there are following technical problems for the prior art:
The incomplete situation of cortex of bone on the outside for the treatment of fractured near end of thighbone, such as anti-intertrochanteric fracture, greater trochanter lateral wall
Comminuted fracture etc.;Near end of thighbone form is bent, and bending moment of face is larger, and the inside of bending is on the pressure side, the outside of bending is embodied
Tension in the case of cortex of bone is incomplete on the outside of the near end of thighbone, resists outside tension part material deficiency, tensile stress completely by
Inner matter intramedullary needle is resisted, and stress can be concentrated on around intramedullary needle nail hole, be easy to cause the fracture of intramedullary needle.
