An acetabular reconstruction plate for effective fixation of posterior acetabular wall fractures

Abstract

The invention relates to an acetabulum reconstruction plate for effectively fixing acetabular posterior wall fracture, belongs to the technical field of osteopathic medical appliances, and is used for effectively fixing acetabular posterior wall fracture. According to the technical scheme provided by the invention, the acetabulum reconstruction plate comprises a strip-shaped bone fracture plate and multiple hooks arranged on one side of the bone fracture plate in parallel, wherein the upper ends of the hooks are fixedly connected with the edge of the bone fracture plate, the lower parts of the hooks are bent, and the bent curvature degree are matched with the acetabular posterior wall. According to the acetabulum reconstruction plate with the structure, the hooks on one side of the bone fracture plate recline against the outside of the acetabular posterior wall fracture block, the acetabular posterior wall fracture block can be fixed directly or the hooks can be inserted into the fracture block for fixing, therefore satisfied treatment effect on severely injured acetabular posterior wall is achieved as well as sequela and subsequent surgeries caused by acetabular posterior wall injury are prevented. The acetabulum reconstruction plate has the advantages of simple structure, convenience in use and significant benefits; by the adoption of the acetabulum reconstruction plate, unexpected good effect can be achieved, the difficulty in treatment of acetabular posterior wall injury can be solved, therefore the acetabulum reconstruction plate is worthy of popularizing and using.

Description

technical field [0001] The invention relates to an acetabular reconstruction plate for treating acetabular posterior wall fracture, and belongs to the technical field of orthopedic medical devices. Background technique [0002] The acetabulum is an important weight-bearing joint that constitutes the lower limbs of the human body, and its fractures are mostly high-energy injuries, which are more common in young people. Acetabular fractures are intra-articular fractures. Treatment should be based on clinical manifestations, imaging evaluation and other factors. Anatomical reduction, strong immobilization, and early initiation of active and passive functional exercises are required. [0003] Surgery has become the mainstay of treatment for acetabular fractures. According to the literature, Letoural and Matta demonstrated that postoperative displacement < 1 mm is less likely to develop traumatic arthritis, while postoperative displacement of 1-3 mm is more likely to dev...
