Background
The human humeral shaft is in a cylindrical shape, the far end of the shaft is divided into an inner humeral branch and an outer humeral branch, the shape of the fan is similar to a flat and wide fan, a forward inclination included angle exists between the fan and the axis of the humeral shaft, and the humeral condyle is thinner, so that fracture is easy to occur. The fracture of the distal humerus is one of the common fractures of the elbow, and in recent years, with the increase of traffic accidents and the aging of society, the incidence rate tends to increase. The fracture of the distal humerus mainly comprises supracondylar, intercondylar and capitulum of the humerus, simple fractures which involve inner and outer condyles and the like, the fracture part has specificity and complexity of anatomy, and in addition, due to osteoporosis and the pulverization of joints and metaphysis, once fracture occurs, most fractures are comminuted, and the treatment is very troublesome. Most of the existing humerus far-end external rear side anatomical fixing plates have single functions, different steel plates are required to be selected for osteotomy and fracture fixation, and the comminuted fracture of the joint surface needs to be assisted and fixed by other implants such as hollow nails and the like, so that the existing humerus far-end external rear side anatomical fixing plates can not meet the clinical use requirements of fracture fixation or osteotomy at multiple positions of the humerus far end.
Based on this, there is a need to design a humerus distal external posterior anatomical fixation plate to solve the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a humerus distal end outside rear side dissection fixing plate aiming at the problem that the humerus distal end fixing plate in the prior art can only be applied to a position.
Realize the utility model discloses the technical scheme of purpose is: a humerus far-end external rear side dissection fixing plate comprises a fixing plate head and a fixing plate body which is integrally formed with the fixing plate head; the rear end surface of the head of the fixing plate is in an inwards concave arc shape; the head of the fixing plate comprises a head body and a side wing which is arranged on one side of the head body and can be broken off; the fixing plate body, the head body and the side wings are all provided with a plurality of fixing holes.
The joint of the head body and the side wing is provided with a breaking groove.
The fixing holes on the head body are four quincunx threaded holes.
The side wings are butterfly-shaped.
The fixing holes on the side wings are five quincunx threaded holes which are tightly arranged.
The fixing holes on the fixing plate body are five pressurizing holes which are uniformly distributed along the length direction of the fixing plate body.
By adopting the technical scheme, the utility model discloses following beneficial effect has: (1) the utility model discloses set up the flank of breakable, the flank position can be to the fixed of comminuted fracture, can regard as conventional coaptation board to use after the flank rupture, and the suitability is strong.
(2) The utility model discloses set up the rupture groove, can easily break the flank when needs are broken.
(3) The utility model discloses a flank setting is the butterfly, can coincide more with the upper arm bone distal end, and is fixed effectual.
(4) The utility model discloses set up plum blossom mold fixed orifices, fixed effectual.
(5) The utility model discloses set up the pressure port, further improved fixed effect.

Detailed Description
(example 1)
Referring to fig. 1 and 2, the humerus distal external posterior anatomical fixation plate of the present embodiment includes a fixation plate head 1 and a fixation plate body 2 integrally formed with the fixation plate head 1.
The back end surface of the head part 1 of the fixing plate is in a concave arc shape. The head part 1 of the fixing plate comprises a head body 1-1 and a side wing 1-2 which is arranged at one side of the head body 1-1 and can be broken off. The fixing plate body 2, the head body 1-1 and the side wings 1-2 are all provided with a plurality of fixing holes.
Furthermore, a breaking groove 3 is formed at the connecting part of the head body 1-1 and the side wing 1-2, so that the side wing 1-2 can be easily broken when needing to be broken.
Furthermore, the fixing holes on the head body 1-1 are four quincunx threaded holes so as to improve the fixing effect.
Furthermore, the side wings 1-2 are butterfly-shaped, can be more inosculated with the distal end of the humerus, and are good in fixing effect.
Furthermore, the fixing holes on the side wings 1-2 are five quincunx threaded holes which are tightly arranged, so that the fixation of the comminuted fracture part can be improved.
Further, the fixed orifices on the fixed plate body 2 are five pressurizing holes uniformly distributed along the length direction of the fixed plate body 2, so that the fixing effect can be further improved.
In the embodiment, the breakable side wings 1-2 are arranged, so that the positions of the side wings 1-2 can be fixed aiming at comminuted fracture, and the broken side wings 1-2 can be used as a conventional bone fracture plate, so that the applicability is strong.
The humerus distal external posterior anatomical fixation plate of the present embodiment also has the following advantages:
1. effective fixation is provided for fracture of the distal lateral articular surface of the humerus (humerus capitulum fracture).
2. Aiming at the AO-typed C-shaped fracture of the humerus far-end fracture, the fixing mode has strong adaptability and the fixation is effectively carried out.
3. The fixing range can reach the external humeral epicondyle, and can provide fixation for the external humeral epicondyle osteotomy.
4. An effective fixation of the intercondylar fracture of the humerus can be provided in combination with the medial humeral plate.
5 may provide support for a posterior sidewall fracture of the distal humerus joint.
6, the fixing is firm, and the function exercise can be performed as early as possible.
7. For humeral intercondylar fractures, two modes of 90-degree fixation and 180-degree fixation can be achieved.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
