Peri-acetabular prosthesis structure

Abstract

The invention provides a peri-acetabular prosthesis structure. The peri-acetabular prosthesis structure comprises an acetabular cup, an ilium supporting body, an ischium supporting body and a pubis supporting body. The ilium supporting body, the ischium supporting body and the pubis supporting body are all arranged on the acetabular cup. The acetabular cup is connected with the ilium osteotomy face of the pelvis through the ilium supporting body, connected with the ischium osteotomy face of the pelvis through the ischium supporting body, and connected with the pubis osteotomy face of the pelvis through the pubis supporting body. In this way, after hemipelvectomy surgery, firm fixiation of a hemipelvic prosthesis in the early stage of reconstruction is realized, and later-stage complications like screw breakage, prosthetic loosening and dearticulation can be prevented. The problem of an artificial hemipelvic prosthesis in the prior art that complications like screw breakage, prosthetic loosening and dearticulation are likely to occur in the later stage is solved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a prosthesis structure around the acetabulum. Background technique [0002] Acetabular tumor is a kind of tumor, and it is rare for it to occur in the acetabulum alone. Most acetabular tumors are destroyed by the tumor together with the ilium or pubic ischium, and even the entire hip bone is completely involved, thus forming the acetabulum surrounding tumors. [0003] At present, hemipelvic amputation can achieve a radical goal, but it is difficult for patients to accept it because of the loss of the affected limb. In order to enable the patient to obtain a complete affected limb after hemipelvic amputation, the current acetabular reconstruction methods can meet the requirements. The acetabular reconstruction methods mainly include: tumor bone inactivation and replantation, allogeneic half pelvis transplantation and artificial half pelvis. Pelvic prosthetic reconstruction, etc....
