Description
Technical field
The present invention relates to a kind of orthopaedics internal fixtion connector.
Background technology
When treatment children's hip deformity, distal femur are lopsided, need first maleformation to be blocked, then use lockplate and bone screw to be coupled together fracture both sides according to correct anatomic form.Not being exclusively used in the lockplate (also known as steel plate) that treatment children's hip is lopsided, distal femur is lopsided and fracture at present clinically, is all replace with lockplate with adult.The structure of adult's lockplate is as shown in Figure 11 and Figure 10, the plate body 1 ' of strip is provided with multiple screw hole 6 ' running through the inside and outside surface of plate body 1 ', and the inner side of plate body 1 ' has the groove 11 ' of longitudinally Axis Extension and between every two adjacent screw holes 6 ', offers the shallow slot 12 ' of one transverse direction.During use, several pieces of bone screw are each passed through screw hole 6 ' corresponding on this lockplate and lock, are fixed on the backbone of fracture both sides.Although groove 11 ' and each shallow slot 12 ' can make this lockplate be adjacent to the backbone of fracture both sides.But during treatment children's hip deformity people be the fracture that causes near femoral trochanteric, use the lockplate of this board-type can not be adjacent to tuberosity part and the backbone of fracture both sides, orthopedic effect is poor, fixes undesirable.
Summary of the invention
The present invention aims to provide a kind of children's's osteotomy lockplate, and solve the shortcoming of other adult's lockplates when treatment children's hip is lopsided, distal femur is lopsided and fracture, that realizes ideal is fixing.
Technical scheme of the present invention is: children's's osteotomy lockplate, and on the plate body of strip, longitudinally axis has multiple bone screw, and the front end of this plate body is provided with the flat head of outwards bending, and the width of this head is greater than the width of plate body; On this head, longitudinally axis has guide pinhole, has longitudinal bone screw at rear portion in front portion, and the position being positioned at longitudinal axis both sides between guide pinhole and this longitudinal bone screw offers left bone screw and right bone screw respectively; The axis being parallel of the axis of guide pinhole and the axis of left bone screw and right bone screw, the angle between the axis of guide pinhole and plate body lower surface is 90-150 degree, and the angle between the axis of guide pinhole and the axis of longitudinal bone screw is 0-20 degree; Be used for the treatment of hip varus and Methods for Distal Femoral Fractures.
A kind of version is had to be: described head is provided with the platform parallel with plate body, and described guide pinhole, longitudinal bone screw, left bone screw and right bone screw are all established on the platform.Angle between the axis of guide pinhole and plate body lower surface is 100-120 degree, and the angle between the axis of guide pinhole and the axis of longitudinal bone screw is 20 degree.This structure treat hip turn up and femoral supracondylar fracture time more to fit the anatomical structure of children's, improve orthopedic effect, improve fixed property.
Implement in structure preferred: the inner side of described plate body and head all has the arc groove of longitudinally Axis Extension, the axis of described left bone screw and the axis of described right bone screw are located on the different RADIAL of two of this arc groove cross section respectively.This structure can make plate body and head more press close to fracture both sides in using state, and consequently head three bone screw form many level-crossings at patient femur's tuberosity part and fix, and improves anti-ly to cut out power.Overall fixed property and stability are improved.
Children's's osteotomy lockplate of the present invention is by the cranial anatomy configuration design of outwards bending, and the convenient fracture both sides being correctly placed on treatment children's hip deformity, form correct orthopedic location.Head porous locking design, can realize good biomechanics distribution at children's's femoral trochanteric, provide angle stability and improve resisting pull out forces, reaching the effect of Titanic micro-plates.By the angle design of the different bone screw of head, different specifications the clinical demand of various patient can be met.
