hip prosthesis

Abstract

The present invention provides a hip bone prosthesis comprising a prosthetic body having an arcuate structure, an acetabular cup and a connection device, wherein the prosthetic body comprises a first end and a second end; the first end cooperates with the sacrum in a contact way; and the acetabular cup is connected to the second end by the connection device with the adjustable position. The technical scheme of the invention can effectively solve the problems that the supporting effect of a screw and rod system is unreliable and fatigue crack is liable to cause in the prior art.

Description

technical field

[0001] The invention relates to the field of medical devices, in particular to a hip bone prosthesis. Background technique

[0002] The pelvis is a common site for bone tumors, and pelvic tumors can be divided into primary tumors and metastatic tumors. The former are mainly chondrosarcoma, osteosarcoma, and Ewing sarcoma, while the latter is commonly seen in bone metastases of breast cancer, kidney cancer, prostate cancer, and lung cancer. The onset of pelvic tumors is insidious and difficult to diagnose early, and the extent of invasion is often large when discovered. In addition, the anatomy around the pelvis is complex and adjacent to many important organs. The operation is difficult, with many complications, poor curative effect, and high mortality. At present, hemipelvic resection or modified hemipelvic resection and amputation are mainly used for pelvic tumors. However, the resection of any pelvic tumor will cause bone defects, which will lead to inte...
