Combined type steel plate for closing fibulas on two sides after fibula section osteotomy

Abstract

The invention provides a combined type steel plate for closing fibulas on the two sides after fibula section osteotomy, and belongs to the technical field of orthopedic medical instruments. The combined type steel plate is used for closing and fixing the broken ends of the fibulas on the two sides after the fibula section osteotomy. According to the technical scheme, after the fibula section osteotomy, a near-side steel plate body and a far-side steel plate body are fixed to the fibulas on the two sides respectively through fixing screws; then the far-side steel plate body and the near-side steel plate body are closed through a restoration instrument and then are fixedly connected through connection bolts, and therefore the two ends of the broken fibulas are closed; the outer side tension of the knee joint is enhanced manually, and the varus deformity of the knee joint is better corrected. The combined type steel plate is reasonable in structure, accurate in locating, firm in fixing, and capable of effectively tensioning the broken ends of the cut fibulas, increases the sedimentation rate of the fibulas, and improves the operation efficacy. The combined type steel plate is an innovation to osteoarthritis through the fibula osteotomy, effectively overcomes the defect of a knee replacement, solves the problem which is not solved for a long time, greatly shortens the operation time and recovery time, and has good social benefits and economic benefits.

Description

technical field [0001] The invention relates to a combined steel plate for drawing and fixing fibular broken ends on both sides after fibula segmental osteotomy, and belongs to the technical field of orthopedic medical devices. Background technique [0002] The knee joint is an important load-bearing intermediate device of the human body. In recent years, with the acceleration of global aging and the increase of obesity rate, the incidence of knee osteoarthritis has also increased significantly. Since the inner side of the knee joint bears 60-80% of the weight of the whole body, the wear and tear of the cartilage on the inner side of the knee joint becomes more common and serious. Knee osteoarthritis in the late stage is most likely to cause varying degrees of varus deformity. Patients mainly present with joint pain, swelling, stiffness, and dysfunction. In severe cases, the quality of daily life and work can be significantly reduced. For knee osteoarthritis (especially in ...
