Medical acetabulum compensation prosthesis

Abstract

The invention provides a medical acetabulum compensation prosthesis. The medical acetabulum compensation prosthesis comprises a body portion, a top portion and locking screws. The body portion comprises an inner side surface, an outer side surface and a lower surface, wherein the shape of the inner side surface coincides with the shape of the surface of an ilium to be contacted, the inner side surface is used for making contact with the surface of the ilium to be contacted and being fixedly connected with the surface of the ilium to be contacted, the inner side surface can be a surface which is processed through roughening, and the initial stability can be conveniently improved through a plurality of stud-shaped protrusions; mounting holes are formed in the outer side surface, and threads can be formed in the mounting holes; the radian of the lower surface is matched with the surface of cartilage in an acetabulum, and a continuous surface can be formed. The top portion is connected with the body portion at a certain angle, is of a blade plate structure, and is used for being inserted into the ilium to conduct fixation. The locking screws are used for penetrating through the mounting holes to fix the body portion to the ilium. The medical acetabulum compensation prosthesis can have the effects that load bearing is assisted, the stress is conducted, a skeleton of a poorly-developed part is replaced, and upward movement of a femoral head is prevented after the medical acetabulum compensation prosthesis is implanted. According to the medical acetabulum compensation prosthesis, implantation operation is easy, the trauma is minimal, and replacement and overhauling treatment are easy.

Description

technical field [0001] The invention belongs to the technical field of acetabular repair prosthesis, in particular to a medical acetabular compensating prosthesis. Background technique [0002] Acetabular dysplasia is a common clinical disease. Patients often suffer from femoral head dislocation and osteoarthritis, and conservative treatment is ineffective. At present, the main surgical treatment methods include osteotomy and artificial total hip replacement in the later stage of the disease, all of which have limitations such as large trauma, uncertain long-term effect, and loose and worn prosthesis. For early disease and younger patients, there are currently no suitable medical implants that can delay the development of lesions. Contents of the invention [0003] The purpose of the present invention is to provide a medical acetabular compensation prosthesis, which is used to further cover the femoral head of patients with acetabular dysplasia, to prevent its upward move...
