Ilium wing filled prosthesis

Abstract

The invention relates to the technical field of medical prosthesis, and discloses an ilium wing filled prosthesis. The ilium wing filled prosthesis includes: a prosthesis body including a bone contactsurface for connecting to a surface of a bone defect of a human ilium, a soft tissue contact surface for connecting with the soft tissue of the human body, and a ridge surface joined by the outer edge of the ilium ridge of the human ilium; a stereoscopic porous structural layer formed on the bone contact surface and / or the soft tissue contact surface and / or the ridge surface; and at least one fixing member, wherein the fixing member is sequentially connected to the ilium of the human body through the ridge surface and the bone contact surface to fix the prosthesis body to the ilium of the human body. The ilium wing filling prosthesis of the present invention is capable of better filling the ilium after bone removal.

Description

technical field [0001] The invention relates to the technical field of medical prosthesis, in particular to an iliac wing filling prosthesis. Background technique [0002] The ilium is located in the pelvic region of the central axis of the human body. It participates in the formation of the hip joint, the load bearing of the lower limbs, and the accommodation of the pelvic viscera. At the same time, it forms an important body curve together with the buttocks. It is an important anatomical structure of human biomechanics and aesthetics. Because the bone quality of the ilium is cancellous bone, and the bone mass is relatively large, in clinical medical operations, part of the ilium is often taken as a material for human bone transplantation. Iliac crest bone harvesting and bone grafting are widely used clinically in patients with bone trauma, tumors, nonunions, and joint repairs. [0003] However, in the traditional clinical ilium bone harvesting, no filling is done after th...

Problems solved by technology

[0003] However, in the traditional clinical ilium bone harvesting, no filling is done after the bone harvesting, or only bone cement is used for filling, which will easily lead to the following defects in the ilium after bone harvesting: On the one hand, if the bone is not Filling will cause local bone depression after bone extraction from the ilium, which will easily pull the skin on it and cause discomfort such as local irritation and compression pain; on the other hand, if no filling or only Filling with bone cement will cause obvious asymmetry between the left and right sides of the iliac crest after bone extraction, which directly affects the appearance and body curve; in addition, when the amount of bone harvested from the ilium is large, it will not only affect the hip joint Stability, and even cause fracture of the superior iliac crest, and make the ilium form a local weak area, so that the pelvic viscera may have a hernia problem, which seriously affects the visceral function
