Description
Technical field
This utility model relates to technical field of medical instruments, specifically, is a kind of proximal tibia bone plate system。
Background technology
Fracture of the tibial plateau is the damage that a kind of orthopaedic trauma is common, and along with the increase day by day of vehicle accident, its sickness rate is also in rising trend。Fracture of the tibial plateau belongs to intra-articular fracture, how to affect knee joint function because of tibial plateau damage of articular surface, and treatment difficulty is big, very easily leaves over joint function disturbance。
In recent years, for the ease of to treatment for tibial plateau fracture, tibial plateau having been carried out typing, i.e. tibial plateau mixed lateral column, medial side of tibial plateau post, tibial plateau rear pillar。It adopts the blade plate for the treatment of can be divided into outer side steel plates, rear outside blade plate, afterwards inner side blade plate, inner side blade plate。
Its outer side steel plates is placed in outside before tibial plateau, and it must reach the requirement of dependable performance, should meet biomechanical characterization and meet anatomical features again。Inadequate in the nail bit quantity of condyles, being also not sufficiently stable after fixing, brings a lot of unfavorable factor to postoperative fracture healing and rehabilitation exercise, and plate shape is poor with the goodness of fit of surface of bone form simultaneously, increase the stimulation to soft tissue after implant surgery relatively big, patient can be made not feel well。
Rear outside blade plate is placed in outside after tibial plateau, the posterolateral anatomical structure of tibial plateau is complicated and neural blood vessel and important tendon are covered with in this, therefore after traditional tibial plateau, outside fixed form is first indirect first by after bone reduction via outside before tibial plateau, outside after being entered to by front outside, indirectly fix again, but this fixed form often faces and cannot be resetted or fixing in outside after tibial plateau, in addition the posterolateral hone lamella of tibial plateau it is specifically used for also very rare, therefore the blade plate utilizing other position sometimes it is only capable of outside fracture after tibial plateau to be fixed, but its hone lamella plate shape is poor with the goodness of fit of surface of bone, and comfort level is also not very good after implanting。
Rear inner side blade plate is disposed primarily in inside after tibial plateau, and Main Function is to reach fixing sclerite and maintain tibial plateau leveling, generally selects L-shaped steel plate or cuts " Herba Trifolii Pratentis " the shape steel plate etc. at tip, it is impossible to be completely docile in postartis shape in prior art。
Inner side blade plate is disposed primarily in medial side of tibial plateau side to the rear。Owing to fracture of the tibial plateau is to have knee joint to turn up to cause, the general inner side of platform articular surface is fissure fracture, but walk the damage merging ligament of outside backward inside fracture line Chang Youqian more, part loading surface fragmentation and subside, curative effect is not good enough, often leaves over traumatic arthritis, joint instability and joint function disturbance etc.。Prior art generally adopts the method for inner side blade plate attachment screw treat, but existing inner side blade plate has the disadvantage that 1. existing inner side blade plates are imprecise by front introversion posterolateral medial side of tibial plateau fracture fixation to major part fracture line trend；2. tibial plateau articular surface can not reach anatomical reduction。
