Description
Technical Field
The utility model relates to the technical field of locking bone plates, in particular to a semi-surrounding type anatomical locking bone plate for fixing the front edge of a tibial plateau.
Background
The proximal enlarged portion of the tibia includes the cortex of the metaphyseal end, cancellous bone, and the articular surface. This anatomical region is called the tibial plateau in orthopedics.
Tibial plateau fractures are common lower limb fractures, and common treatment modes include internal fixation and external fixation. The internal fixation treatment mode mainly comprises the steps of cutting the skin subcutaneous part at the fracture part of the cortical bone, placing the bone fracture plate through the incision to enable the bone fracture plate to cross the fracture position, and fixing the bone fracture plate at two ends of the fracture part by using screws, so that broken or free bone blocks are effectively fixed.
The existing locking bone fracture plate has certain defects when in use. When the existing front inner side locking bone plate or front outer side bone plate is used, the front inner area and the front outer side area of the tibia platform can be fixed only, three parts of the front inner area, the bare area and the front outer side area of the tibia platform can not be fixed at the same time, multiple groups of locking bone plates are needed to be fixed at multiple positions, and the operation incision and the economic cost of patients are increased. The total strength of the multiple bone plates to fix multiple locations respectively is also inferior to that of a single integrally formed bone plate. The existing monolithic bone plates have failed to meet the higher demands of clinical fixation protocols for stability and economy.
To this end, we propose a semi-encircling anatomic locking bone plate that secures the anterior edge of the tibial plateau.
