Abstract

The invention provides an acetabular defect reconstructive prosthesis, which comprises an ilium support and an acetabulum cup, wherein the ilium support comprises a support base and a connecting wing plate which is arranged on the support base; the support base gets into contact with an ilium; and the acetabulum cup is connected to the support base in a rotatable mode. According to the technical scheme of the invention, problems of the prior art on peripheral acetabular defect reconstruction and long-term stability are effectively solved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an acetabular defect reconstruction prosthesis. Background technique [0002] Periacetabular tumors include various primary malignant tumors, metastatic cancers, and more aggressive benign tumors, such as giant cell tumor of bone. Surgical resection is the main treatment for pelvic tumors. Due to the advancement of surgical technology, it is now possible to perform extensive or radical surgical resection on the former, and extensive and critical resection and curettage on the latter two. Extensive resection of pelvic tumors usually results in a large bone defect, which interrupts the continuity of the pelvis and loses part of the surrounding soft tissue, requiring reconstruction of the defective pelvis. Depending on the experience of the operator and the condition of the patient, reconstruction methods vary. There is not yet enough evidence to say which method of reconstruct...
