Abstract
The invention discloses a bone fracture plate device for the distal femur fracture. The bone fracture plate device comprises a main bone fracture plate body and an auxiliary bone fracture plate body. An arc-shaped protrusion is arranged at the position, close to the distal femur, of the bottom face of the main bone fracture plate body, multiple temporary screw holes are formed in the front end and the rear end of the arc-shaped protrusion respectively, and grooves are formed in the positions, around the arc-shaped protrusion, of the main bone fracture plate body. The auxiliary bone fracture plate body and the grooves are matched in size, an open groove corresponding to the arc-shaped protrusion is formed in the middle of the auxiliary bone fracture plate body, and screw holes corresponding to the temporary screw holes are formed in the front end and the rear end of the open groove. When the arc-shaped protrusion of the main bone fracture plate body is inserted into a positioning groove of the auxiliary bone fracture plate body, the auxiliary bone fracture plate body is embedded into the grooves of the main bone fracture plate body, and meanwhile the temporary screw holes correspond to the screw holes. Stable and firm fixation can be achieved, and eccentric fixation and bone nonunion are effectively avoided.
Description
Technical field
The present invention relates to medical instruments field, is the implanting device of a treatment Methods for Distal Femoral Fractures, is specifically related to a kind of blade plate device for Methods for Distal Femoral Fractures.
Background technology
Micro wound coaptation plate osteopathy (MIPO) is a kind of technology of modern fracture fixation, it adopts succinct reduction of the fracture technology, utilize the Interal fixation without pressurization to maintain fracture reduction, surgical exposure and soft tissue extent of exfoliation are reached and minimizes, improve union of fracture rate.The treatment means of current Methods for Distal Femoral Fractures generally has following several method: the first is distal femur dissection type bone fracture plate, this blade plate is the internal fixtion implant comparatively early occurred, be characterized in designing the anatomic form meeting distal femur, Clinical practice is very convenient, but not row " locking " design between its screw and steel plate; The second is distal femur anatomical type locking plate, this blade plate is on the basis of the first distal femur dissection type bone fracture plate, locking design is used between hold-down screw and blade plate, like this after screw is screwed into femur, screw thread between tail cap and blade plate mutually can be engaged and form stable fixing, the advantage of this design is the stability significantly increasing blade plate, improves the healing rate of fracture.
Above two kinds of internal fixation methods its all have a common shortcoming to be eccentric fixing, for N/D inside distal femur, do not accompany the fracture of bone cips, therapeutic effect is all more satisfactory, and for inner side bony defect or can not desirable to reset with bone cips, as butterfly bone block, all formed outside the localised tension band strong point after generally fixing and move, blade plate stress raisers, to break plate and bone does not connect so be easy to form blade plate clinically, this is the difficult point of current Methods for Distal Femoral Fractures clinical treatment.
The third method is that distal femur beats intramedullary pin, the advantage of this inside-fixture is that of avoiding the shortcoming of above blade plate, change bias is fixed as center and fixes, simultaneously, because the transverse section of intramedullary pin is circular, more lateral separation is had compared with the cross section of blade plate, so the distance having the hone lamella that connects safer between its medial support band and the tension band in outside, clinically safer internal fixtion can be provided to support for Methods for Distal Femoral Fractures, be the prefered method solving Methods for Distal Femoral Fractures companion inner side Cranial defect at present clinically.But, it also exposes a lot of problems in clinical, need to open knee joint when being first its interplantation, postoperative knee joint function is had a certain impact, secondly, because the pulp cavity of distal femur is the destructing of horn mouth sample, the implantation of intramedullary pin can not reach well stable, although the pinning of far-end can reach the stable of part, because it is fixed on spongy bone, and there is no between itself and main portions and fixedly secure, so it is enough stable that distal femur can not be made to obtain.Clinical is that bone does not connect has higher incidence rate.
Summary of the invention
Goal of the invention: be solve problems of the prior art, the invention provides and a kind ofly avoid eccentric fixing, the fixing firm and blade plate device for Methods for Distal Femoral Fractures that fixing mortality is low.
Technical scheme: for realizing above-mentioned technical purpose, blade plate device for Methods for Distal Femoral Fractures of the present invention comprises blade plate mainboard, described blade plate mainboard has a top side face with one for contacting the bottom side of distal femur, some screw holes are respectively arranged with in top side face and bottom side surface, described blade plate device also comprises a blade plate subplate, described blade plate mainboard is provided with an arc-shaped protrusions in the bottom surface of bottom side one end, the rear and front end of described arc-shaped protrusions is respectively arranged with some interim screw holes, described blade plate mainboard offers groove around described arc-shaped protrusions, the size of described blade plate subplate and the size of described groove suitable, described blade plate subplate is provided with the open slot corresponding with described arc-shaped protrusions at middle part, the rear and front end of open slot is provided with the screw corresponding with described interim screw hole, when the arc-shaped protrusions of described blade plate mainboard inserts the open slot of described blade plate subplate, described blade plate subplate is embedded into the inside grooves of described blade plate mainboard, meanwhile, described interim screw hole is corresponding with described screw.
Preferably, described arc-shaped protrusions is circular arc, and chord length is 5 ~ 10cm, and sagitta is 5 ~ 30mm, and thickness is 0.5 ~ 3mm.
10 ~ 20cm of the centre distance blade plate mainboard far-end of the chord length of described arc-shaped protrusions.
Preferably, the screw hole on described blade plate mainboard surface is lock hole, and the screw on described subplate surface is circular hole.
When Clinical practice, first according to Methods for Distal Femoral Fractures conventional method, enter along vastus intermedius and vastus lateralis gap, expose fracture site, conventional RESET fracture site.Getting blade plate subplate and fracture fixed by interim screw, now noting when placing blade plate subplate, need to place for mainboard afterwards and screw fixedly leaves enough spaces, avoid mainboard hold-down screw empty beyond sclerotin.Goose saw, along blade plate subplate intermediate gap, along femur longitudinal grooved, then places blade plate mainboard, makes blade plate mainboard cover blade plate subplate, is screwed into screw after the perforate of electric drill femur.Take out subplate temporary fixed screw, electric drill inserts formal screw after reaming again.Side seam block in further reduction, is then fixed by the screw hole of blade plate mainboard both sides, then closes operative incision complete operation.
Beneficial effect: compared with prior art, tool of the present invention has the following advantages:
(1) by the design of the arc convex of blade plate mainboard bottom surface, blade plate perfection can be made to realize moving in press belt, effective separation tension band and press belt, the problem of stress concentration of blade plate before effectively avoiding, avoid the fracture of blade plate, the problem of fracture delayed union and disunion, meanwhile, complete implantation due to knee joint need not be opened, so do not worry the postoperative impact on knee joint function;
(2) by the setting of blade plate subplate, convenient operation person carries out pre-determined bit to fracture, improves the accuracy of operation;
(3) by the cooperation of blade plate mainboard and blade plate subplate, ensure that fixing stability on the one hand, too increase the motility of operation on the other hand, be convenient to doctor's operation, reduce the incidence rate of bone does not connect.
