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
The present invention relates to the interior fixed connecting piece of a kind of orthopaedics.
Background technology
When treatment children's hip deformity, distal femur are lopsided, need first maleformation is blocked, then use lockplate and bone screw that the fracture both sides are coupled together according to correct anatomic form.Not being exclusively used in clinically at present the lockplate (claiming again steel plate) that treatment children's hip is lopsided, distal femur is lopsided and fracture, is all to replace with lockplate with the adult.The adult uses the structure of lockplate as shown in Figure 11 and Figure 10, the plate body 1 ' of strip is provided with a plurality of screw holes 6 ' that run through plate body the 1 ' inside and outside surface, and the inboard of plate body 1 ' has the groove 11 ' of Axis Extension longitudinally and offer horizontal shallow slot 12 ' one between every two adjacent screw holes 6 '.During use, several pieces of bone screw are locked, are fixed on the backbone of fracture both sides through screw hole 6 ' corresponding on this lockplate respectively.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 the 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, fixing undesirable.
summary of the invention
The present invention aims to provide a kind of children's's osteotomy lockplate, solves treatment children's hip deformity, distal femur is lopsided and other adults are by the shortcoming of lockplate during fracture, and that realizes ideal is fixing.
Technical scheme of the present invention is: children's's osteotomy lockplate, on the plate body of strip longitudinally axis have a plurality of bone screw, the front end of this plate body is provided with the head of outward, the width of this head is greater than the width of plate body; On this head longitudinally axis forwardly have guide pinhole, have vertical bone screw at rear portion, and left bone screw and right bone screw are offered respectively in the position that is positioned at the longitudinal axis both sides between guide pinhole and this vertical bone screw; The axis of guide pinhole is parallel with the axis of the axis of left bone screw and right bone screw, and the angle between the axis of guide pinhole and plate body lower surface is the 90-150 degree, and the angle between the axis of the axis of guide pinhole and vertical bone screw is the 0-20 degree.
Have a kind of version to be: described head is provided with the platform parallel with plate body, and described guide pinhole, vertical bone screw, left bone screw and right bone screw all are located on this platform.This structure, in the anatomical structure for the treatment of when hip turns up with femoral supracondylar fracture the children's that more can fit, is improved orthopedic effect, improves fixed property.
In preferred enforcement structure: the inboard of described plate body and head all has the longitudinally arc groove of Axis Extension, and the axis of described left bone screw and the axis of described right bone screw are located at respectively on two different RADIALs of this arc groove cross section.This structure can make plate body and head more press close to the fracture both sides in using state, and consequently three bone screw of head form many crossing on the same levels at patient's femoral trochanteric and fix, and improves the anti-power that cuts out.Whole fixed property and stability are improved.
Children's's osteotomy lockplate of the present invention is by the cranial anatomy configuration design of outward, and the convenient fracture both sides that correctly are placed on treatment children's hip deformity, form correct orthopedic location.Head porous locking design, can realize that good biomechanics distributes at children's's femoral trochanteric, angle stability is provided and improves resistance to plucking and exert oneself, and reaches strong interior fixing effect.By the angle design of the different bone screw of head, can different specifications meet various patients' clinical demand.
