Problems solved by technology

[0002] Femoral bone defects are very common in patients with severe osteoporosis, patients with severe skeletal deformities, or patients with osteolysis of the femur after the failure of the first artificial joint replacement. adverse effects on the postoperative stability of the body
[0003] There are two methods of repairing bone defects recorded in the related art, one is to use natural bone as filling bone, but the source of natural bone is less, especially in China, the source of allogeneic bone is more scarce due to cultural and legal restrictions; The second is to use artificial bone as a filler. Artificial bone is generally made of bioceramics or metal. Although its osteoinductive properties and biocompatibility are excellent, its bearing capacity is not good; some operations use bone cement filling. It is carried out in the same way as artificial bone, but there is a problem of poor stability after bone defect treatment

Abstract

The invention relates to a medical instrument, in particular to a femoral bone defect hip joint treatment prosthesis which is characterized in that the femoral bone defect hip joint treatment prosthesis comprises a patch, a base plate is formed at one end of the patch, and the base plate extends towards the lateral direction of the patch; at least one mounting hole for placing a bone nail is formed in the base plate; and the purpose of improving the stability and the reliability after the femoral bone defect treatment is achieved.

Description

technical field [0001] The application relates to a medical device, in particular to a hip joint treatment prosthesis for femoral bone defect. Background technique [0002] Femoral bone defects are very common in patients with severe osteoporosis, patients with severe skeletal deformities, or patients with osteolysis of the femur after the failure of the first artificial joint replacement. adverse effects on the postoperative stability of the body.
