Technical Field
The utility model relates to the technical field of acromioclavicular joint dislocation, in particular to an anatomical locking device aiming at acromioclavicular joint dislocation.

Dislocation of acromioclavicular joint fracture is a common injury in orthopedics. Due to the gravity action of the upper limb, after the peak of the clavicle shoulder is fractured or the ligament of the acromioclavicular joint is damaged, the fractured end or the acromioclavicular joint is easy to shift or dislocate, the conservative treatment effect is poor, and the operation treatment is often needed.
At present, the shoulder lock hook steel plate is generally used for fixing the shoulder lock joint clinically and treating patients with dislocation or subluxation of the shoulder lock joint and distal clavicle fracture. Because the shoulder latch hook is pressed and fixed by the gap behind the acromion, local acromion avascular necrosis and acromion subacromolysis are easily caused after the operation. In addition, acromioclavicular impaction syndrome is often caused by the acromioclavicular impaction syndrome, and the shoulder joint of a postoperative patient is continuously painful, even has limited movement or can not be lifted and is stiff. Due to the micromotion of the acromioclavicular joint, the risk of internal fixation failure such as loosening and unhooking of the steel plate and even hook breakage also exists. The traditional kirschner wire fixing method has high failure rate due to unreliable fixation, looseness, slippage and other reasons of the kirschner wire, and is rarely used. The acromioclavicular joint fixing steel plate is researched and designed, but internal fixing failure complications such as nail withdrawal and plate breakage and the like frequently occur after operation due to insufficient fixing strength.
