Abstract
The utility model relates to a proximal tibia outer side anatomical locking plate. The plate consists of a flat and long main body part and a head part, wherein a plurality of locking holes or/and pressurizing holes are formed in the main body part; the head part is divided into a head part near end and a head part remote end; the head part near end is flat and long and is vertical to the main body part; the edge of the head part near end is round and obtuse; four locking holes are formed in the head part near end; the rear side of the head part near end has the characteristic of a reconstruction plate and is an inwards bent arc; the part, connected with the main body part, of the head part remote end is obliquely bent; and a plurality of angle-forming locking holes, a small through hole and an aiming frame positioning hole are formed in the head part remote end. The plate has the positive effects that due to the adoption of the four holes in the head part near end, the back of the outer side of a tibia platform can be fixed, and the indication is expanded; the rear side of the head part near end has the characteristic of the reconstruction plate, so that the plate is conveniently cut and bent by a doctor; due to the adoption of a pre-plastic type low-incisura anatomical bone fracture plate, the stimulation to parenchyma is reduced; and due to the adoption of angle-forming locking holes in the head part remote end, a steel plate has high angle-forming and rotating stability.
Description
[technical field]
This utility model relates to the surgical medical equipment technical field, specifically, is a kind of proximal tibia outside anatomical form lockplate.
[background technology]
Tibial plateau is a knee joint important load structure, and fracture of the tibial plateau (fracture of tibial plateau) is one of modal fracture in the knee joint wound.Fracture of the tibial plateau can be caused by indirect violence or direct violence.When high falling was hindered, foot landed earlier, falls down to the side again; The conduction of power is made progress along tibia by foot; The acceleration that falls conducts the power of body weight downwards. and combined effect is in knee, because the twisting resistance that the side falls down to the ground and produces causes tibial medial or outside platform collapsed fracture.When violence directly hit knee joint inboard or outside when surveying, make knee joint turn up or in turn over, cause the outside or inboard platform to be fractured or ligament injury.Because fracture of the tibial plateau is typical intra-articular fracture, it is handled with prognosis will produce very big influence to knee joint function.Fracture of the tibial plateau is usually with articular cartilage, knee ligament or meniscal damage, and missed diagnosis possibly cause deformity of knee, the line of force or stable problem with dealing with improperly all, causes the obstacle of function of joint.Thereby, be the important topic in the knee joint the traumatology department for the diagnosis of fracture of the tibial plateau with handling.
The Schatzker typing that fracture of the tibial plateau is commonly used is to be proposed in 1979 by Schatzker.It is divided into six types to fracture of the tibial plateau: the I type---simple outside platform fissure fracture, and the typical non-comminuted fracture piece of wedge shape outwards descends the splitting displacement, and this kind of fracture is common in no osteoporotic young patient; II type---outside platform splitting merges depressed fracture, and side sphenoid piece splitting separates, and has articular surface compression downwards to be absorbed in metaphysis, and this kind of fracture is most commonly in the gerontal patient; III type---the central compression fracture of simple outside platform, articular surface is compressed and is absorbed in platform, and outside cortex is complete, is prone to betide osteoporosis person; IV type---interior condylar fracture, this kind of fracture can be simple wedge shape splitting or pulverizing and compression fractures, often involve the tibia sour jujube; V type---bicondylar fracture, both sides tibial plateau splitting, characteristic is that metaphysis and backbone still keep seriality; The VI type---with metaphysis and key isolating platform fracture, except that single condyle, two condyle and articular surface fracture, also there are horizontal shape of proximal tibia or oblique fracture.Wherein Schatzker I type, II type, III type are that typical low-yield damage causes, and complicated IV type, V type, VI type fracture are then caused by the high-energy damage.
According to patient's different situations, carry out the selection of Therapeutic Method at present.Operative treatment generally can be divided into internal fixation and external fixation.And in the internal fixation treatment method that the author pays close attention at present; Generally be to adopt lag screw, T-steel plate, L shaped steel plate, golf steel plate etc. to fix according to concrete typing; But outer front side is fixed generally to tibial plateau in steel plate is fixing, externally the fixing weakness of proceeds posterolateral.
[utility model content]
The purpose of this utility model is to overcome the deficiency of prior art; A kind of proximal tibia outside anatomical form lockplate is provided; Its form and lateral of tibia surface of bone are more identical; Not only can fix simultaneously, can also carry out fixed preformed shape anatomical form lockplate the outer proceeds posterolateral of tibial plateau to the outer front side of tibial plateau.
The purpose of this utility model realizes through following technical scheme:
A kind of proximal tibia outside anatomical form lockplate is characterized in that, is made up of cadre and head; Described head is divided into head near-end and head far-end; The part diagonal that described head far-end is connected with the cadre is crooked.
Described cadre is flat elongated, and some lock holes or pressurization hole are arranged on it, and cadre's far-end is tapered, and far-end is shuttle type structure, is convenient to implant; Cadre's near-end matches with the proximal tibia anatomic form toward the outer side.
Described head, the head near-end is flat elongated, and is basic vertical with the cadre, and the edge circle is blunt; The head near-end applying tibial plateau outside is crooked arcuation, runs through tibial plateau near-end lateral surface always; Can fix the outer proceeds posterolateral of proximal tibia; The head near-end is provided with four lock holes, and the head proximal rearward partly is the reconstruction plate characteristic, makes things convenient for doctor's cutting and curved; The part diagonal that the head far-end is connected with the cadre is crooked, like golf clubs; The head far-end toward the outer side, applying proximal tibia relevant position; The head far-end is provided with some angled lockings hole, increases into angle stability; The head far-end is provided with some small through hole, in order to squeeze into Kirschner wire; For the matching with micro-traumatic operation, can be provided with some diopter locating holes simultaneously.
This utility model can be used for proximal tibia fracture, metaphysis fracture, intra-articular fracture, Periprosthetic fracture etc.
Compared with prior art, the good effect of this utility model is:
(1) head near-end four holes of this utility model design can be fixed the outer proceeds posterolateral of tibial plateau, has enlarged its indication;
(2) this utility model head proximal rearward undulate makes things convenient for doctor's cutting and curved;
(3) the preformed type of this utility model, low incisura anatomical form blade plate has reduced soft tissue irritation, does not need the blade plate bending basically;
(4) the head far-end angled locking hole of this utility model makes steel plate have better one-tenth angle and rotational stabilization.
