Abstract

The invention discloses a combined type self-pelvis prosthesis. The combined type self-pelvis prosthesis comprises an artificial whole-hip joint and a pedicle screw rod fixation system. The artificialwhole-hip joint comprises an acetabulum prosthesis and a short rod. The acetabulum prosthesis is in a hollow semi-spherical shape, the concave side of the acetabulum prosthesis is used for the caputfemoris at the near end of thigh bone to be embedded, and the convex face of the acetabulum prosthesis is provided with at least three short rods. The pedicle screw rod fixation system comprises a titanium rod and a pedicle screw for fixing the vertebral pedicle. The first end of the titanium rod is fixedly connected with the short rods, and the second end of the titanium rod is fixedly connectedwith the pedicle screw. By flexibly arranging the short rod positions of the artificial whole-hip joint in cooperation with the pedicle screw rod fixation system, the combined type self-pelvis prosthesis has the advantages of being simple in structure, adjustable in installing angle and small in installing condition limitation.

Description

technical field [0001] Embodiments of the present invention relate to artificial prosthesis technology, and in particular to a composite semi-pelvic prosthesis. Background technique [0002] Currently, surgical resection is the most effective treatment for malignant tumors in the hemipelvis, and the huge bone defect after surgery is mainly reconstructed with a hemipelvic prosthesis. The main advantages of the hemipelvic prosthesis include: the source is not limited by the donor; it can be temporarily assembled during the operation and has a wide range of applications; the limb function can be restored in a short period of time after the operation; surgical complications and prosthetic complications are acceptable. These advantages make it the most widely used reconstruction method for large pelvic bone defects. After many years of use both at home and abroad, there are many retrospective studies with long-term follow-up to confirm its safety and effectiveness. [0003] The...
