Description
Technical Field
The utility model belongs to the technical field of medical equipment and specifically relates to a board is dissected to children's thighbone near-end front side.
Background
The bone callus can be formed in the early stage of the slightly displaced and angled femoral trochanteric fracture of the child, so that the fracture end can be firmly healed quickly, and the femoral shaft of the child has certain natural correction capability, so that generally, the pursuit of anatomical reduction by an operation method is unnecessary, and the ideal curative effect can be achieved by a conservative treatment method such as traditional skin traction and hip herringbone gypsum fixation. However, the conventional traction methods such as Thomas skeletal traction, Hamilton Russell traction and the like have many defects and possible serious complications, such as skin necrosis, ischemic muscle contracture, traction pinhole infection, easy over-traction or insufficient traction force, difficult ideal correction of angular or rotational displacement, serious nursing tasks in bed and the like. Surgery remains a good treatment option for some particular types of patients (e.g., patients with multiple fractures, pathological fractures, and poor skin conditions, which are not amenable to traction or conservative treatment). The literature shows that a great number of reports of success in treating children femoral trochanteric fracture by using various internal identification methods exist at home and abroad; as the large and small tuberosities of the femur and the epiphyses at the femoral head are closed in the 15-17 years old, the fracture of the trochanteric part of the femur of the child is fixed in the reduction operation to cause local epiphyseal injury or aggravate the original injury risk. For example, internal fixation methods such as intramedullary nails or angle steel plates have the possibility of damaging trochanter epiphysis to cause bone development disorder, long leg deformity, hip valgus, femoral head necrosis or dysplasia and the like besides infection risks; due to the characteristic of continuous growth and development of children, no proper internal fixing material at the front side of the rotor part is available in the market at present, only a femoral shaft single skin is fixed in the market at present, the plate is easily broken, the fixation is not firm, and great potential safety hazards exist; to this end, a proximal anterior anatomical plate for children's femurs is proposed to solve the above mentioned problems.

Detailed Description
The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
As shown in fig. 1-3, the utility model provides a board is dissected to children's thighbone near-end front side, including fixed plate 8, a plurality of fourth screw holes 5 have been seted up on the surface of 8 front ends of fixed plate, fixed surface is connected with key shape board 7 to the slope of upper end front side on the fixed plate 8, key shape hole 4 has been seted up on 7 front end surfaces of key shape board, 7 upper end fixed surface of key shape board is connected with arc 6.
The surface of the front end of the fixing plate 8 is provided with a plurality of fourth screw holes 5, and the fourth screw holes 5 are used for tightly fixing the fixing plate 8 at the femoral stem of a patient; the opening number of the fourth screw holes 5 is set according to the height and leg length of the patient; the arc-shaped plate 6 is a fixed rotor or femoral neck base; the key plate 7 is inclined towards the upper end and the front side so as to adapt to the anteversion angle of the femoral neck of the patient; the anteversion angle is the angle between the axis of a certain part of the human body and the coronal plane of the human body. The normal range is 10-15 degrees, and the anteversion angle of the femoral neck is the included angle formed by the axis of the femoral neck and the frontal plane of the femoral condyle (namely the coronal plane of the human body); since the fracture positions of each patient are different, the nailing position and direction can be adjusted according to the direction of the fracture line by the key-shaped hole 4 formed on the front end surface of the key-shaped plate 7.
The right end of the arc-shaped plate 6 is inclined downwards, the left end of the arc-shaped plate 6 is inclined upwards, and the front end face and the rear end face of the arc-shaped plate 6 are both arc-shaped; a first screw hole 1 is formed in the left side of the front end surface of the arc-shaped plate 6, a second screw hole 2 is formed in the middle of the front end surface of the arc-shaped plate 6, and a third screw hole 3 is formed in the right side of the front end surface of the arc-shaped plate 6; the front end and the rear end of the key plate 7 are both arc-shaped.
The front end surface and the rear end surface of the key plate 7 are arc-shaped and are used for adapting to the torsion angle of a patient; the torsion angle refers to the rotation of the distal end or the proximal end along the longitudinal axis of the limb during the development of a certain part of the human body or under the action of external force, such as spiral fracture caused by torsion violence. Because the distal end and the proximal end of the limb are not on the same coronal plane due to rotation, the included angle between the two coronal planes is the torsion angle. The femoral neck torsion angle is the included angle formed by the femoral neck coronal plane and the femoral condyle coronal plane (namely the human body coronal plane); the front end surface and the rear end surface of the arc-shaped plate 6 are arc-shaped and are used for adapting to the anatomical radian of the base part of the femoral neck of a patient; the function of the arc-shaped plate 6 that the right end is inclined downwards and the left end is inclined forwards is to adapt to the neck angle of the femur of the patient; the front end face and the rear end face of the arc-shaped plate 6 are arc-shaped, the right end of the arc-shaped plate inclines downwards, the left end of the arc-shaped plate inclines upwards, the key-shaped plate 7 inclines upwards, and the front end face and the rear end face are arc-shaped, so that the steel plates can be tightly combined to be fixed at the position of thighbone, double-skin fixation is realized, and the plate is not easy to break and is firm.
The utility model discloses when using, terminal surface is the arc for arc form, right-hand member downward sloping, left end upper end slope and 7 upslopes of key shape board, front and back terminal surface through arc 6 around, can combine closely to fix the steel sheet in thighbone department, makes it realize that two skin matter are fixed, and difficult disconnected board is just firm, improves the security performance.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or scope of the invention as defined in the appended claims.
