Abstract

The present invention provides a femoral component and a single condyle prosthesis containing the femoral component. The femoral component is applied in a condyle joint prosthesis replacement and comprises a femoral support body and a connection component, the femoral support body is used for connecting a femur; the connection component is detachably arranged on the femoral support body to connectthe femoral support body with the femur; and wherein the connection component comprises a plurality of connectors, the plurality of the connectors are selectively arranged on the femoral support bodyto avoid defect locations on the femur and connect the femoral support body to the femur. The femoral component solves a problem that in the prior art, femoral components cannot be effectively fixedon defect femoral condyles.

Description

technical field [0001] The invention relates to the field of medical prosthesis, in particular to a femoral component and a unicondyle prosthesis having the same. Background technique [0002] There are two types of unicompartmental prosthesis currently used in the field of medical prosthesis: movable type and fixed type. The fixation of the femoral components of the two unicompartmental prostheses is realized through the fixed column or anti-rotation rib. The existing fixed column or anti-rotation rib is integrally formed with the tibial tray. The femoral condyle is used in a good state, but when there is a defect in the femoral condyle, the existing fixation post or anti-rotation rib of the femoral component cannot be effectively fixed in the place with good bone quality of the femoral condyle, which may cause postoperative femoral component and tibial fracture. Support loosening, prosthesis revision. Contents of the invention [0003] The main purpose of the present i...
