Embodiment Construction

[0022] In order to make the content of the present invention easier to be understood clearly, the following further describes the present invention in detail based on specific embodiments in conjunction with the accompanying drawings.

[0023] Such as figure 1 , figure 2 As shown, a femoral shaft transverse fracture side wing type bone plate includes a main bone plate 1 and two sets of wing pairs distributed on the main bone plate 1. The two sets of wing pairs are symmetrically distributed on the main bone plate 1. The main bone plate between the wing pairs is the fracture part bone plate 3, which is used to correspond to the fracture position. The thickness of the fracture part bone plate 3 is 2mm thicker than the thickness of the main bone plate 1 at other positions; each group of wing pairs consists of two The side wings 2 are composed of two side wings 2 symmetrically distributed on both sides of the main bone plate 1; the main bone plate 1 is provided with a locking threade...

Abstract

The invention discloses a flank-type bone plate for transverse fracture of a femoral shaft. The bone plate comprises a main bone plate and two flank pairs distributed on the main bone plate symmetrically, and the main bone plate between the two flank pairs is fracture bone plate for corresponding to a fracture part; the thickness of the fracture bone plate is 2 mm thicker than that of other positions of the main bone plate, and each flank pair comprises two flanks which are distributed on the two side of the main bone plate symmetrically; the main bone plate is provided with locking screw holes and a pressing screw hole, the pressing screw hole is arranged on the fracture bone plate, and locking screw holes are arranged on each flank. The flank-type bone plate ensures the stability and safety of the fixed bone plate in the fracture of the femoral shaft, can reduce the damage to the bone plate from stress concentration, has a remarkably increased bearing capacity, and embodies the superiority of a bone plate system.

Description

Technical field [0001] The invention relates to a wing-type bone plate for transverse fracture of the femoral shaft, belonging to the technical field of bone plates. Background technique [0002] Due to the emergence of the theory that applying pressure to the fracture site helps to heal, the dynamic compression plate (DCP) has gradually been developed. In order to overcome defects such as secondary fractures after the removal of the bone plate and the contact between the bone and the bone plate leading to cortical necrosis, a bone plate that reduces the contact area between the bone plates and damages the cortical blood supply is invented on the basis of DCP. , Called the limited contact dynamic compression plate (LC-DCP). The Perren research team further improved the bone plate and designed a point contact internal fixation (PC-Fix) system for the above problems. On the basis of retaining the respective advantages of traditional LC-DCP and PC-Fix, using the principle of threa...
