Abstract

The invention provides a femoral near-end sleeve component which comprises a sleeve body (10). A penetrated containing channel is formed in the sleeve body (10), and the near end of a femoral stem prosthesis (20) penetrates the containing channel. The technical scheme of the component effectively solves the problem that large-scale bone defect can be caused as the prosthesis and bone cement need to be taken out when a femoral side is repaired in the prior art.

Description

technical field [0001] The invention relates to the technical field of femoral prostheses, in particular to a femoral proximal sleeve assembly. Background technique [0002] At present, artificial hip replacement has been widely used in clinical treatment. It is one of the standard operations for the treatment of hip joint diseases. It can relieve pain, improve joint function, and restore joint stability and limb function. However, due to the problems of the material of the hip joint prosthesis itself and the replacement technique, complications such as loosening and dislocation may also occur after surgery. Revision is required when the above complications occur. [0003] In the prior art, large-scale bone defects on the femoral side caused by osteolysis, stress shielding, prosthesis and bone cement removal are common and difficult problems during revision. For example, the prosthesis and bone cement need to be removed during femoral revision. In order to remove the prost...
