Description
(1) technical field
This utility model relates to a kind of blade plate, particularly relates to a kind of blade plate that is applied in the tibial plateau rear side.
(2) background technology
Fracture of the tibial plateau is common intra-articular fracture, often is due to the high-octane violence.Report fracture of the tibial plateau such as Watson account for about 1% of whole fracture, and platform fracture in the outside accounts for 55%～70%, and inboard platform fracture accounts for 10%～23%, and the medial and lateral platform is fractured simultaneously and accounted for 10%～30%.Severe patient also can merge meniscus or knee joint peripheral ligament injury.Because of knee joint inner structure complexity, and be the heavy burden joint, cause the knee joint function obstacle so cause various complication easily after injured.Though there is not generally acknowledged therapeutic regimen at present, along with deepening continuously that fracture of the tibial plateau is studied, Therapeutic Method is also in progressively improvement and perfect.But along with increasing of high energy damage in recent years, the pathological change of fracture of the tibial plateau also becomes increasingly complex, and causes treatment very difficult.The subject matter that exists is that fracture is difficult to satisfied resetting, and the fracture fragments instability can not be effectively fixing, is difficult to early exercise and postoperative infection.
Fracture of the tibial plateau is divided three classes according to the direction of external force: the outer condylar fracture due to the stress of turning up of 1. serving as reasons at most, system is subjected to when standing due to violence strike or the indirect external force, as when high falling lands, knee joint is for turning up position or external force due to the femoral lateral condyle bump tuberosity of bitia,external.2. pressure at right angle, to the conduction of tibia straight line, then femur two condyles impact tibial plateau downwards to external force along femur, can cause that the inside and outside condyle of tibia fractures simultaneously, can form " Y " type or T-shape fracture, and displacement downwards.3. turn over stress in, cause in the femur condyle and press down tibial plateau and cause the tuberosity of tibia,internal fracture, cause inwardly below displacement of sclerite, subside.
Fracture of the tibial plateau is an intra-articular fracture, and treatment should be followed the intra-articular fracture Therapeutic Principle.The Therapeutic Principle comprises making sink and the sclerite of splitting resets, and recovers the smooth and line of force correct of articular surface. correct in knee or interior talipes varus. recover the function in joint to greatest extent. and the generation of minimizing traumatic arthritis.Bone grafting after anatomical reduction, strong internal fixation and collapsed fracture reset is considered to the satisfied three elements of fracture of the tibial plateau treatment.
At present, quite ripe to the inside and outside surgical treatment of fracture technology of tibial plateau, internal fixation material is selected very many, but because the particularity of tibial plateau rear side anatomical structure, treatment tibial plateau rear side fracture does not form unified, complete therapeutic scheme as yet, does not also have the blade plate of specialized application at the tibial plateau rear side.Carry out support fixation after having the scholar to attempt adopting appropriate pre-bendings such as reconstruction plate, T steel plate, small-sized T steel plate and Herba Trifolii Pratentis steel plate clinically, but these blade plates relatively are applicable to the tibial plateau inboard and the outside, but can't meet tibial plateau rear side surface feature, when tibial plateau rear fracture or interior outside platform fracture rearward were shifted, just there were various defectives in these steel plates.Exist shortcomings such as steel plate is blocked up, moulding difficulty as the T-steel plate, be difficult to form effectively and fix, and the reconstruction plate longitudinal holding power is limited, be difficult to avoid in the fracture healing process because bone resorption and muscle ligament pulling force cause articular surface to sink; L shaped steel plate has satisfied support force, uncontrollable fracture lateral displacement; Other a little shaped steel plates also exist and are difficult to accurately mouldingly attach with fracture end, if problems such as inadequate moulding then armor plate strength weakens, as a whole, in these inside-fixtures all can not meet behind the proximal tibia that there are differences, the morphosis of the outside, back, cause clinical effectiveness not satisfied.
The day for announcing be on April 16th, 2003 patent No. be 01226324.9 Chinese utility model patent tibial plateau syntripsis blade plate, subordinate side, L termination at existing L shaped steel plate sets up alar part, alar part is provided with screw, T-steel plate and L shaped steel plate organically are bonded together, integrate both advantages.But these blade plates relatively are applicable to the tibial plateau inboard and the outside, when tibial plateau rear fracture or interior outside platform fracture rearward are shifted, because the tibial plateau rear has important nerve, blood vessel to pass through, and the horizontal hone lamella of existing blade plate upper end can have a strong impact on these nerves and blood vessel.The blade plate of specialized application at the tibial plateau rear side also do not appear at present.
