Description
Technical field
The present invention relates to a kind of medical anatomical form and support locking and pressurizing synthetism steel plate, rear side dissection type support locking bone fracture plate in especially a kind of proximal tibial platform.The supporting role that its tibial plateau rear pillar that is used for being caused by fracture in operative treatment subsides is played a supporting role by this support locking plate is fixed in bone with lock screw in the operation, makes the tibial plateau rear pillar recover normal configuration state.Belong to technical field of medical.
Background technology
Medical dissection type support locking steel plate is the fracture fixation apparatus that has the locking screw thread hole, can above-mentioned steel plate fixedly be reached the angle Stabilization by screw.The screwed hole of lockplate can be Combination nail hole, both can use lock screw, also can use traditional non-locking screw (being also referred to as the conjunction type steel plate).Locking steel plate just was used to spinal surgery and decorative sursery before 20 years.The late period eighties in last century is up to the mid-90, and the research of various dissimilar bone fracture internal fixing device material has promoted lockplate to be applied to the internal fixation of fracturing.The emphasis of initial research reduces extensively peeling off and damaging of soft tissue when being the held stationary fracture.Some factors of clinicing aspect have also promoted the development of lockplate, mainly comprise: the aged osteoporotic fracture patient in high-energy damage patient's survival rate rising, West Europe and North America constantly increase and patient and doctor dissatisfied to the therapeutic effect of some special fracture around joint.Non-clinical sexual factor comprises industry popular gradually to the development of new technique and new markets and Minimally Invasive Surgery technology.
As long as any traditionally steel plate can use fixed angle/one-tenth angle to stablize screw or bolt can both be used as locking steel plate.Locking steel plate is compared with general steel plate, and topmost biomechanics difference is that the latter must be to the pressurization of the steel plate on the skeleton, and the frictional force that relies between bone-steel plate interface provides stable.Along with the continuous increase of axial load, screw begins to toggle, and frictional force is reduced, and causes steel plate loosening.If this situation takes place early, it is unstable that fracture will take place, and causes graft failure.Therefore, obtain and keep closely screw fixing difficult more (for example, when the metaphysis of bone and osteoporotic bone), keep stable just difficult more.
There is the defective on the biomechanics in general steel plate, because it can influence the blood operation of fracture site to the periosteum pressurization.Utilize general steel plate that fracture is carried out strong fixing (for example, pressurization and lag screw technology between fracture site) following complication easily takes place: infection, internal fixation failure, fracture delayed union and bone does not connect connect.
Comparatively speaking, locking steel plate is followed the biomechanical principle of external fixation, does not rely on the frictional force between steel plate and skeleton.Owing between screw and steel plate, have into the angle stable interface, do not contact skeleton when allowing to place locking steel plate fully, be the inner fixer that meets the biomechanics viewpoint therefore.In essence, locking steel plate still can be counted as subcutaneous external fixator, only because the distance between it and skeleton is shorter just more firm.Present trend is that production firm provides the anatomical plate that has locking device, as the anatomical plate and the calcaneus anatomical plate of anatomical plate, proximal humerus and the far-end of near end of thighbone and far-end.Under many circumstances, the design of locking steel plate allows steel plate to contact with skeleton is less, can protect the blood of periosteum to supply and the skeleton perfusion like this.In addition, the locking steel plate system also has other characteristics, if any the outside support handle, holds tool and passivity edge, these can make things convenient for the doctor by flesh down or Wicresoft's mode such as subcutaneous steel plate is inserted fracture site.
The anatomical form that both at home and abroad tibial plateau rear side (rear pillar) surgical treatment of fracture is not also adapted supports the locking and pressurizing steel plate at present.In operation, still need the interim pre-bending of steel plate at other positions, make it to stick use, and intensity and the degree of applying ointment or plaster all descend after the steel plate bending, firmly the also corresponding decline of degree and influence therapeutic effect with the tibia rear side.

The specific embodiment
The present invention is as medical implants in vivo, in operative treatment the tibial plateau rear pillar that is caused by fracture subsided and plays a supporting role, and by fixed support of the present invention, makes the platform rear pillar recover normal configuration state relation.Below, with reference to accompanying drawing, embodiments of the present invention are described.
The present invention is by measuring the anatomy relationship of a large amount of (about 2600 examples) Chinese's tibial plateau rear sides (rear pillar), obtain following data and on this basis design finish.The tibial plateau width is generally 75 ± 5cm.Present two arcuate structures at platform rear side horizontal plane, the inner arc central angle is 120 ° ± 15 ° behind platform, and the outer arc central angle is 105 ° ± 20 ° behind platform.It is Z-shaped that sagittal plane is, two corners, and the inboard first corner angle is 40 ° ± 8 °; The outside first corner angle is 40 ° ± 7.5 °; The inboard second corner angle is 45 ° ± 5 °; The outside second corner angle is 45 ° ± 6 °.
With reference to Fig. 1～Fig. 2, the structure of embodiments of the present invention is described.
Head is tetragon roughly, is formed through a plurality of holes at this head; With the cadre who is connected with head, be elongated strip, be formed through a plurality of holes this cadre.The a plurality of holes that are formed at head are arranged as: be two rows in the longitudinal direction; On width, first row is four, and second row is two, wherein, roughly arrange with the end side almost parallel ground of head in first row and second row's hole, and any in the vertical direction in a plurality of holes of any in a plurality of holes of first row and second row is not arranged in string.In addition, first row's size and second row's the varying in size of hole, and the hole that first row's boring ratio second is arranged is big.The hole that is formed at the cadre is a substantially elliptical.Head is bending ground with the cadre and is connected.
Tibial plateau rear side anatomical form locking and pressurizing synthetism steel plate of the present invention is on the basis of traditional blade plate, adopts steel, non-corrodibility metal materials such as titanium, a kind of novel blade plate of being developed in conjunction with AO inner fixed support principle.Need not pre-bending in the anatomical form locking bone fracture plate art of the present invention, need not large tracts of land and expose fracture end, adopt less invasive techniques in the operation, the injury of soft tissue is reduced to minimum, obviously reduce the inner matter failure, significantly reduce the incidence rate that infects with bone does not connect, can multi-angle fix fracture by lock screw, column stability behind the increase platform, the use of tibial plateau rear-side anatomical-form bone fracture plate of the present invention meets BO internal fixation principle fully, especially for complicated fracture wide application prospect and incomparable advantage is arranged.
When using tibial plateau rear side anatomical form locking and pressurizing synthetism steel plate of the present invention to treat fracture of the tibial plateau, can there be certain interval between metaphysis portion and surface of bone under the rare occasion, makes steel plate seem docile inadequately.In such cases, it is moulding that the way of general steel plate is to use lever to carry out, but the multi-shaft locking steel plate is because moulding in advance, there is the probability of destroying latch-up structure in bending once more, so should avoid again moulding for the metaphysial section of steel plate, even fixing back is docile inadequately with surface of bone, do not influence the fixed stability in the large of lock screw yet.Secondly, answer conventional row CT three-dimensional reconstruction before the art, so that judge shape, size and the direction of displacement of all sclerites, design the direction of all lock screw in advance, the situation that can effectively avoid lock screw to interfere with each other or pass bony surface in sclerotin takes place.Under the prerequisite that should the bone fixation piece interfere with each other again, should lock screw be placed different angles as far as possible, help increasing the stability of locking steel plate like this.
Compare with the common supporting steel plate that previously uses, this locking steel plate can carry out the interior fixing of high stable, avoids resetting and loses. In addition; locking steel plate is very limited with contacting of periosteal tissue, and is littler to the compressing that periosteum causes, thereby avoided the generation of periosteum necrosis; help to protect the blood confession of affected area, this may also be one of reason that the nonunion rate descends behind the use Complicated Fracture in Caging Steel Therapy fracture around joint. After screw was screwed into, locking steel plate and lock screw were had a style of one's own, and became a stable system, and no matter the good contraposition that can keep fracturing for normal sclerotin or osteoporotic case, all can provide stronger mechanics to stablize line.
Different from common locking steel plate is, the locking screw design of the multi-shaft locking steel plate that the present invention adopts is special, when screw screws in lock hole, groove phase interlock in screw thread around the head of screw and the lock hole, so that lock hole expands gradually, lock screw thoroughly is fixed on the selected angle and direction the most at last, and before locking fully, lock hole can rotate freely, and lock screw can be adjusted along 40 ° of taper tracks, to guarantee resetting and the adjustment of lock screw direction of sclerite. Therefore, except the treatment advantage of above-mentioned common locking steel plate, the multi-shaft locking steel plate also can accurately be fixed according to the trend of fracture line, and the operation of revising screw orientation in the art is also simple, and needn't be as the nail road that reapposes and plan screw as the single shaft locking steel plate.
Comminuted fracture in the joint, tibial plateau medial and lateral malleolus fracture and Methods for Distal Femoral Fractures are extremely unsettled fracture. After articular surface carried out anatomical reduction, the ossa articularia folded block must reset with the backbone and be connected, and keeps the suitable lower limb line of force. For making union, it is very difficult obtaining enough stability. When the outside uses general steel plate to be fixed, inboard must increase in addition steel plate or outside fixedly support fracture. Difference between this locking steel plate and general steel plate on mechanics is so that locking steel plate is more stable. The acquisition of this locking steel plate stability and keep and do not rely on the interface between steel plate-bone and depend on the stable steel plate-screw interface of angulation. Locking this stable structure of internal fixation device is so that the lock screw pull-out strength will be far above the general steel plate screw. Because screw all is locked on the steel plate, so be difficult to occur single nail puller nail or loosening.
It is very helpful that the higher stability that locking steel plate of the present invention provides is treated following fracture for the surgeon: relatively poor fracture, comminuted bicondylar fracture or any very unstable and single steel plate of bone mass can not provide the fracture of enough stability. Because this locking steel plate must not fit tightly with bone in the time of fixedly, so need only peel off less soft tissue, keep local blood supply and promote union.
Compare with general steel plate, tibial plateau rear side anatomical form locking and pressurizing bone-fracture fixation steel plate of the present invention is in biomethanics and advantage biologically, so that these novel implants have obtained extensive use in recent years.
