Technical Field
The utility model belongs to the technical field of the coaptation, concretely relates to outside coaptation board for tibial plateau.
Background
The metaphyseal end and articular surface of the proximal end of the tibia, referred to as the anatomical location in orthopaedics as the tibial plateau. The tibial plateau is an important load bearing structure of the knee, and tibial plateau fractures (fractures) are one of the most common fractures in knee trauma. Tibial plateau fractures may be caused by indirect or direct violence. When a high fall is injured, the foot firstly lands on the ground and then falls down to the side, the force is transmitted upwards along the tibia by the foot, the force of the body weight is transmitted downwards by the falling acceleration, the force and the force jointly act on the knee, and the medial or lateral tibial plateau of the tibia collapses and fractures due to the torsional force generated by falling to the side. When violence directly strikes the inside or outside of the knee, the knee joint is everted or inverted, resulting in the fracture of the outside or inside platform or the damage of the ligament. Since tibial plateau fractures are typical intra-articular fractures, their management and prognosis will have a large impact on knee joint function. Tibial plateau fractures are often accompanied by damage to the articular cartilage, knee ligaments, or meniscus, and missing a diagnosis and treatment may cause knee deformity, force lines, or stability problems, resulting in dysfunction of the joint. Thus, diagnosis and treatment of tibial plateau fractures are important issues in knee trauma surgery.
Tibial plateau fracture is always a difficult point of traumatic orthopedic treatment, and particularly the treatment of complex tibial plateau fracture has higher complications and disability rate. Tibial plateau fracture belongs to intra-articular fracture, and needs to achieve anatomical reduction and strong fixation. Especially when the posterior column bone is split or collapsed, the traditional anterior approach incision reduction of the knee and the internal fixation method from the front to the back often cannot achieve the expected treatment effect, and the second-stage reduction loss and the fixation failure are easy to occur.

Detailed Description
The knee anterior approach incision reduction in the prior art treats the tibial plateau fracture by an anterior-posterior internal fixation method, and the adoption of the anterior-lateral approach is caused by the fact that a fibula covers the posterior-lateral quadrant of the tibial plateau and the blocking of the structures of the peroneal nerve and the posterior external corner ligament of the knee joint, which leads to the failure of effective reduction and fixation of the type of bone; although the fracture area can be exposed by adopting a posterior approach, the operation wound is large, important vascular nerves are easy to be damaged, and the treatment of the fracture of the anterior-lateral tibial plateau cannot be considered. The method has the advantages that multiple incisions and multiple bone fracture plates are selected for fixation, if a back-side reconstruction support bone fracture plate is used for fixation in a matching mode of a back-side inverted L-shaped approach, although the fixation effect is good, the operation trauma is large, and the functional recovery of the knee joint after the operation is seriously influenced. If the articular surface does not reach the anatomical reduction, complications such as knee joint instability, traumatic arthritis and the like occur after the operation, which leads to the knee joint dysfunction and the life quality of patients to be reduced.
