Plate for fixing dislocated acromioclavicular joint

Abstract

The invention relates to a plate for fixing dislocated acromioclavicular joint, belonging to the technical field of the orthopedic medical device. The plate for relocating and fixing the dislocated acromioclavicular joint comprises a clavicle positioning plate, an acromion plate and a side fork. The clavicle positioning plate is a rectangular steel plate, and 2 to 5 positioning holes are longitudinally distributed on the surface of the rectangular steel plate; the acromion plate is a rectangular steel or titanium plate, the front part of the acromion plate narrows gradually, the front end is sharp, and the rear part is arranged on one side of the clavicle positioning plate and is connected into a whole body with the front part of the clavicle positioning plate; the side fork is connected to the lower part of one side of the acromion plate and is arranged parallel to the longitudinal axis of the acromion plate; and a gap is left between the side fork and the acromion plate. When the plate for fixing dislocated acromioclavicular joint is in use, the clavicle positioning plate is fixed on the clavicle, the side fork is inserted to the center of the cortex on the upper side and the lower side of the acromion or is arranged below the acromion, and the acromion plate is fixed on the acromion. The plate for fixing dislocated acromioclavicular joint has high fixing strength, is good for repairing the ligament, can avoid the occurrence of the acromion impingement syndrome and cause little damage to the acromioclavicular joint capsule and the ligament around the same.

Description

technical field [0001] The invention relates to a fixation device for treating acromioclavicular joint dislocation, belonging to the technical field of orthopedic medical devices. Background technique [0002] In orthopedic medical surgery, the reduction and fixation of acromioclavicular joint dislocation is an operation that needs to be mastered. The dislocation of the acromioclavicular joint is mostly a direct violent injury, such as a direct impact on the shoulder in a traffic accident. When this part is fractured or dislocated, it can cause varying degrees of damage to the nearby ligaments, resulting in dysfunction of the shoulder joint. There are many surgical methods for the treatment of acromioclavicular joint dislocation. The traditional ones include Kirschner wire tension band fixation, hook plate fixation, and wire fixation. Among these methods, the disadvantage of the Kirschner wire tension band fixation method is that the Kirschner wire is easy to come out, and...

Problems solved by technology

Among these methods, the disadvantage of the Kirschner wire tension band fixation method is that the Kirschner wire is easy to come out, and the fixation is not firm, resulting in anteroposterior instability; and when the hook plate is used to treat acromioclavicular joint dislocation, the distal hook of the hook plate is inserted in the shoulder. The lower part of the acromioclavicular joint ligament is prone to subacromial impingement when th
