Problems solved by technology

However, in the treatment of hip deformity in children, the artificially caused fracture is close to the trochanter of the femur. Using this type of straight locking plate cannot be close to the trochanter and the backbone on both sides of the fracture. The orthopedic effect is poor and the fixation is not ideal.

Embodiment 1

[0021] For the structure of an embodiment of the pediatric osteotomy locking plate of the present invention, please refer to figure 1 with figure 2 . The pediatric osteotomy locking plate is suitable for treating hip valgus and lower femur fractures. Its strip-shaped plate body 1 is provided with three bone screw holes 6 along the longitudinal axis, and the three bone screw holes 6 are all in the shape of an "8". The first half of each bone screw hole 6 is a light hole, and the second half is a screw hole. During the operation, doctors can flexibly use bone screws with polished rods or threaded roots according to needs, so as to ensure the quality of the operation to the greatest extent. A groove 11 extending along the longitudinal axis is formed on the inner side of the plate body 1 and a transverse shallow groove 12 is defined between every two adjacent screw holes 6 . The front end of the board 1 is provided with a head 2 bent outwards, the width of the head 2 is large...

Embodiment 2

[0024] The structure of another embodiment of the pediatric osteotomy locking plate of the present invention is similar to that of the previous embodiment, but its scale is smaller, and it is suitable for minimally invasive surgery to treat hip valgus and lower femur fractures. For its structure, see Figure 4 with Figure 5 . In this pediatric osteotomy locking plate, two bone screw holes 60 are opened on the strip-shaped plate body 10 along the longitudinal axis. The two bone screw holes 60 are both in the shape of "8". The hole and the second half are screw holes. During the operation, doctors can flexibly use bone screws with polished rods or threaded roots according to needs, so as to ensure the quality of the operation to the greatest extent. A groove 110 extending along the longitudinal axis is formed on the inner side of the plate body 10 and a shallow transverse groove 120 is defined between the two screw holes 60 . The front end of the plate body 10 is provided w...

Embodiment 3

[0027] For the structure of the third embodiment of the pediatric osteotomy locking plate of the present invention, please refer to Image 6 with Figure 7 . The pediatric osteotomy locking plate is suitable for treating hip varus and distal femur fractures. Its strip-shaped plate body 100 is provided with four bone screw holes 600 along the longitudinal axis, and the four bone screw holes 600 are all in the shape of an "8" , the first half of each bone screw hole 600 is a light hole, and the second half is a screw hole. A groove 1100 extending along the longitudinal axis is formed on the inner side of the board body 100 and a transverse shallow groove 1200 is defined between every two adjacent screw holes 600 . The front end of the plate body 100 is provided with an outwardly bent head 200, the width of the head 200 is greater than the width of the plate body 100; the head 200 has a guide pin hole 300 at the front along the longitudinal axis, and a guide pin hole 300 at the...

Abstract

The invention relates to a locking plate for infantile osteotomy, in particular to an orthopedic internal fixation connector. An elongated block of the locking plate is provided with a plurality of bone screw holes along the longitudinal axis. The front end of the block is provided with a head bent out. The head is wider than the block. The head is provided with a front needle guide hole along the longitudinal axis and a rear longitudinal bone screw hole. A left bone screw hole and a right bone screw hole are formed between the needle guide hole and the longitudinal bone screw hole on two sides of the longitudinal axis. The axis of the needle guide hole is parallel to the axis of the left bone screw hole and the axis of the right bone screw hole. The included angle between the axis of the needle guide hole and the lower surface of the block is 90-150 degrees. The included angle between the axis of the needle guide hole and the axis of the longitudinal bone screw hole is 0-20 degrees. The locking plate is suitable for the treatment of infantile hip malformation, distal femoral malformation and fracture.

Description

technical field [0001] The invention relates to an internal fixation connector for orthopedics. Background technique [0002] When treating children with hip deformity and distal femur deformity, it is necessary to cut off the deformity first, and then use locking plates and bone screws to connect the two sides of the fracture according to the correct anatomical shape. At present, there is no locking plate (also known as steel plate) dedicated to the treatment of pediatric hip deformities, distal femur deformities and fractures, and all of them are replaced by locking plates for adults. The structure of the locking plate for adults is as follows Figure 11 and Figure 10 As shown, the strip-shaped plate body 1' is provided with a plurality of screw holes 6' penetrating the inner and outer surfaces of the plate body 1', and the inner side of the plate body 1' is provided with a groove 11' extending along the longitudinal axis. A transverse shallow groove 12' is provided bet...
