Acetabulum square area bone fracture plate

Abstract

The invention discloses an acetabulum square area bone fracture plate which belongs to the technical field of orthopedic surgical instruments and is used for effectively fixing acetabular fractures. The technical scheme is as follows: the bone fracture plate has a three-dimensional structure, and the shape of each part of the bone fracture plate is respectively matched with curved shapes of an acetabulum square area, so that each part of the bone fracture plate can effectively fix the acetabular fractures. The bone fracture plate disclosed by the invention can effectively fix acetabular anterior and posterior column fractures at the same time, the coverage and support to the acetabulum square area can be increased by fixing arcuate lines and ischial spine parts of the acetabulum square area, and acetabular anterior and posterior columns can be stably reconstructed from the medial wall of the square area. The bone fracture plate disclosed by the invention is originated in the treatment of hip fractures, has a simple structure, is convenient to use, achieves unexpected good effects, solves difficult problems in the treatment of acetabulum square area bone fractures, has remarkable benefits, and is worthy of popularization.

Description

technical field [0001] The invention relates to a bone plate for treating fractures of the anterior and posterior columns of the acetabulum through the square area of ​​the pelvis, and belongs to the technical field of orthopedic surgical instruments. Background technique [0002] The acetabulum is an important weight-bearing joint that makes up the lower limbs of the human body and is also an important part of the pelvis. The fractures of the acetabulum are mostly high-energy injuries, and they are more common in young people. Fractures around the square of the acetabulum are often accompanied by intra-articular fractures of the acetabulum. The treatment plan should be selected based on various factors such as clinical manifestations and imaging evaluation. Anatomical reduction, firm fixation, and early active and passive functional exercises should be performed. [0003] Surgical treatment has become the main treatment for acetabular fractures. The acetabulum consists of ...

AI Technical Summary

Problems solved by technology

If a single anterior approach is used for surgical treatment, the anterior column can be firmly fixed with a steel plate, and screw fixation from the anterior to the posterior column not only requires a high level of surgeon skills but also does not fix the posterior column firmly

Similarly, using a single posterior approach for treatment is not firm for the fixation of the anterior column

In addition, for fractures comminuted in the square zone, neither anterior nor posterior column plates can be effectively fixed

If the acetabular fragment cannot be firmly fixed, it is prone to redisplacement, causing traumatic arthritis of the hip joint or failure of the operation
