Description

Technical Field

[0001] The utility model belongs to the field of tibial surgery, and particularly relates to a novel anterolateral locking plate for the distal end of the tibia. Background Art

[0002] The tibia is the main supporting bone in the lower leg. It connects the knee joint above and the ankle joint below. It is an extremely important supporting bone for the human body. In clinical surgery, tibial fractures account for a high proportion, especially in young people and older women with osteoporosis. Internal fixation is a treatment method for tibial fractures. The current clinical solutions for tibial fractures mainly include ordinary plates, locking plates, intramedullary nails and hollow nails. Among the internal fixation treatment methods, the locking plate is one of the most commonly used internal fixation methods. The principle of the internal fixation treatment method is to make an incision at the fracture end, place a locking plate, make the locking plate span the fracture position, and use screws to fix the locking plate to the distal and proximal ends of the fracture so that the bones at the fracture ends are effectively fixed. Therefore, the shape of the locking plate is similar to the shape of the bone surface, and a screw hole for inserting screws is opened. At present, the locking plate for the anterior and lateral side of the distal tibia has undergone several generations of product upgrades, and several locking plates have been used clinically. However, due to the diversity of distal tibial fractures, it has been difficult to comprehensively use the locking plate in clinical bone fixation. Utility Model Content
