Acromion anatomy locking steel plate

Technical Field

The utility model relates to the technical field of orthopedic medical instruments, in particular to a acromion anatomical locking steel plate for acromion fracture.

Background

The acromion is a part of the cantilever arm extending forwards from the scapular spine, and is only protected by the scapular spine and surrounding muscular tissues, so that acromion fracture is easy to occur when the acromion is impacted due to weak tissues above the acromion. Acromion fractures are a special type of fracture of the scapula, accounting for about 9% of scapula fractures. Acromion fractures are usually caused by strong direct violent pounding or by upward strong impact of the humerus. In recent years, with the increase of high-energy injuries such as traffic accidents, high-altitude falling injuries and the like, the incidence rate of acromion fractures is increased year by year. The function of the shoulder joint is inevitably affected if the acromion fracture is treated improperly.

Currently, incision reduction internal fixation surgery treatment is advocated for acromion fractures with obvious displacement of more than 10mm, and anatomical reduction is required to be achieved. The traditional operation method comprises the treatment of methods such as a hollow lag screw, a Kirschner wire tension band, a reconstruction steel plate, a clavicle far-end locking steel plate and the like, but the traditional internal fixation has the following problems: 1. the hollow lag screw and the Kirschner wire tension band are not firmly fixed enough, and the early function exercise cannot be met; 2. the reconstruction steel plate and the clavicle distal locking steel plate are generally straight or arc-shaped, do not meet the requirements of scapula acromion anatomical radian, and are often required to be bent and shaped when the steel plate is implanted in an operation; 3. screw holes at the far end of the steel plate are few, and the steel plate cannot meet the effective fixing requirement and is difficult to fix.
