Knee joint plateau steel plate

Abstract

The invention discloses a steel plate for fixing a tibial plateau fracture, and particularly relates to a knee joint plateau steel plate. The whole steel plate is in a Z shape and is composed of a steel plate head, a plate body and a steel plate tail. The steel plate head and the steel plate tail are in rotational symmetry with a rotational angle being 180 degrees. The steel plate head and the steel plate tail are respectively provided with a plurality of through holes. The thickness of the plate body is larger than the thickness of the steel plate head and the thickness of the steel plate tail. The thickness of the steel plate head and the thickness of the steel plate tail are respectively 1.2+/-0.3mm. The thickness of the plate body is 6.0+/-0.3mm. The two sides of the plate body are provided with grooves. The number of the through holes is three. The edge of the steel plate head and the edge of the steel plate tail are respectively in a circular arc shape. The knee joint plateau steel plate has the advantages that an operative route is simple, an operative wound is small, collapse translocation and lateral translocation can be prevented, molding is not needed, and the fixing effect is ideal.

Description

technical field [0001] The invention relates to a steel plate for tibial plateau fracture fixation, in particular to a knee joint plateau plate. Background technique [0002] At present, T-shaped steel plates, L-shaped steel plates, or A0 steel plates are usually used in the treatment of fractures near the knee joint platform. Most of these steel plates are relatively thick, which makes it difficult to perform minimally invasive surgery. It is likely to cause large surgical trauma and difficult wound recovery. When in use, the longitudinal support force of T-shaped steel plate or L-shaped steel plate is limited, it is difficult to control the longitudinal collapse displacement, and the support strength is limited, which is prone to plate breakage; A0 steel plate is difficult to shape, and its support strength is relatively average. The traditional fracture treatment method also needs to pre-bend and cut the steel plate during the operation. The operation is complicated and c...

Problems solved by technology

[0002] At present, T-shaped steel plates, L-shaped steel plates or A0 steel plates are usually used in the treatment of fractures near the knee joint platform. Most of these steel plates are relatively thick, which makes it difficult to achieve minimally invasive surgery, which is likely to cause large surgical trauma and difficult recovery of wounds.

When in use, the longitudinal support force of T-shaped steel plate or L-shaped steel plate is limited, it is difficult to control the longitudinal collapse displacement, and the support strength is limited, and the plate is prone to breakage; the A0 steel plate is difficult to shape, and the support strength is relatively average

The traditional fracture treatment method also needs to pre-bend and cut the steel plate during the operation. The operation is complicated and cannot be completely conformed to the shape of the bone.
