A knee osteoarthritis tibial osteotomy pressurized bone plate

Abstract

A knee osteoarthritis tibial osteotomy compression bone plate belongs to the technical field of orthopedic medical devices and is used for increasing the compression effect of the bone plate. The technical solution is: the upper and lower edges of the planar plate surface of the osteosynthesis plate respectively have a plurality of fixed teeth perpendicular to the plate surface, the fixed teeth are respectively opposite to the tibial bone surfaces on both sides of the osteotomy gap, and the upper parts of the plurality of fixed teeth are respectively There are oblique pressure holes, the axes of the pressure holes are respectively inclined from both sides to the direction of the osteotomy gap, and the pressure screws are fixedly connected to the tibia on both sides of the osteotomy gap through the pressure holes. The present invention is the first creation of tibial osteotomy osteotomy plate, which has the advantages of reasonable structure, convenient use, and can take into account the connection strength and pressurization effect of the bone plate at the same time. The use of this pressurized bone plate can increase the bone grafting pressure in the osteotomy area, Promote bone growth, make osteotomy heal faster, and achieve good surgical results.

Description

technical field [0001] The invention relates to a bone plate used for tibial osteotomy and belongs to the technical field of orthopedic medical devices. Background technique [0002] Knee osteoarthritis is the most common joint disease in the elderly, and it is also the main cause of lower limb disability in the elderly, which seriously affects the daily activities and quality of life of the elderly. Knee osteoarthritis refers to a chronic bone and joint disease caused by cartilage degeneration and bone hyperplasia in the knee joint. Clinically, it is mainly manifested as knee joint pain and dysfunction of varying degrees, and some joint swelling and effusion , X-ray showed narrowing of the joint space, osteophyte formation at the joint margin, subchondral bone sclerosis and cystic degeneration. About 60% of people over the age of 55 have knee osteoarthritis on X-ray films, and 35%-50% of them have clinical manifestations. When the knee joint is varus in elderly patients w...

AI Technical Summary

Problems solved by technology

After a lot of clinical practice, it is found that the obvious problems in the current high tibial osteotomy are: excessive requirements for support strength, neglect of the compression effect, and obvious trade-offs.

Because the current bone plate does not have an effective compression effect in the osteotomy area, there are often problems such as insufficient pressure on the bone graft in the osteotomy area, slow growth, and even poor growth or difficult healing.
