Problems solved by technology

However, it will lead to excessive stripping, so that after the bone plate is placed, there will be no attachment points for muscles and ligaments, resulting in difficulty in suturing, slow postoperative recovery, and even instability of the knee joint in some patients

Embodiment 1

[0019] Such as Figure 1-Figure 3 A distal femur lateral bone plate is shown, which includes a bone plate body 1 with a length of 15-35 cm, a width of 1.5-3.5 cm, and a thickness of 0.3-0.6 cm. The bone plate body 1 is divided into a proximal segment 2 , the middle section 3 and the distal section 4, the proximal section 2 and the middle section 3 are arc-shaped structures, which are the same as the curvature of the anterior arch of the femur, the right end of the proximal section 2 is a blunt triangular structure 5, and the far The end section 4 gradually becomes thinner and twisted from right to left, and is concave and inclined inwardly. Kirschner wire holes 6, proximal locking holes 7 and sliding holes 8, the proximal Kirschner wire holes 6 are located on the blunt triangular structure 5, and the middle section 3 is provided with a plurality of middle locking holes 9 adjacent to the middle A middle Kirschner wire hole 10 is provided between the locking holes 9, and the di...

Embodiment 2

[0021] Such as Figure 1-Figure 3 A distal femur lateral bone plate is shown, which includes a bone plate body 1 with a length of 15-35cm, a width of 1.5-3.5cm, a thickness of 0.3-0.6cm, and a smooth curved surface structure at the edge. 1 is divided into a proximal section 2, a middle section 3 and a distal section 4. The back of the bone plate body 1 is provided with a plurality of arc-shaped grooves 16, and the arc-shaped grooves 16 are symmetrically distributed on both sides of the middle section 3. side, which is beneficial to disperse the stress, and at the same time reduce the impact of the bone plate body 1 on the periosteal blood supply. The proximal section 2 and the middle section 3 are arc-shaped structures, which are the same as the curvature of the anterior femoral arch, with a width of 12 mm and a thickness of 6 mm. The right end of the proximal section 2 is in a blunt triangular structure 5, and the distal section 4 gradually becomes thinner and twisted from ri...

Abstract

The invention discloses a thighbone far-end outer side bone fracture plate which comprises a bone fracture plate body, the bone fracture plate body is divided into a near-end section, a middle section and a far-end section, the right end of the near-end section is of a blunt triangle structure, and the far-end section is gradually thinned, twisted, concaved and inclined inwards from right to left. A near-end kirschner wire hole, a near-end locking hole and a sliding hole are sequentially formed in the near-end section, a middle locking hole and a middle kirschner wire hole are formed in the middle section, a sliding hole I is formed in the middle of the right end of the far-end section, a far-end upper locking hole is formed in the left side of the sliding hole I, a far-end upper kirschner wire hole is formed in the left side of the far-end upper locking hole, a far-end lower locking hole is formed in the left side of the far-end upper kirschner wire hole, and far-end lower kirschner wire holes are formed in the left end of the far-end section along the periphery. The far-end section of the bone fracture plate body is placed in a mode of being attached to the condylar naked area on the outer side of the thighbone, a space is reserved, and the thighbone far-end outer side bone fracture plate does not conflict with fracture type treatment needing absolute pressurization for articular surface intercondylar fracture.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a distal femur lateral bone plate. Background technique [0002] At present, the treatment of distal femoral fractures is mainly based on the AO lateral distal femoral LISS plate. During the operation, the fracture needs to be reduced before the bone plate can be placed. Although some screws can be fixed percutaneously, first reduction and then fixation will inevitably shorten the operation time. Prolonged, increased blood loss and increased chances of infection. At the same time, since the fractures of young patients are mostly comminuted, and the fractures of elderly patients are mostly osteoporosis, compression alone cannot treat fractures well, so the principle of internal fixation with locking screws should be used to treat distal femoral fractures. In addition, only 3 / 4 of the locking hole of the distal lateral LISS plate of the AO femur is threaded, and compared w...
