Problems solved by technology

The Kirschner wire tension band is easy to operate and low in cost, but the Kirschner wire is easy to come out, the fixation is not firm, and the fracture often shifts
The clavicular hook plate is fixed firmly by inserting one side of the hook into the acromion, but it is prone to postoperative shoulder pain, dehooking, and stress fractures

Embodiment Construction

[0019] The present invention will be further described below in conjunction with accompanying drawing:

[0020] The acromioclavicular joint locking hook-plate complex is composed of a hook-plate complex 1, a locking screw 5, a locking main nail 7 and a drilling Kirschner wire 10. There are three threaded holes 2 at one end of the hook-plate complex 1, and 2 to 3 locking screws 5 can be installed according to the fracture fixation situation. There are grooves 4 on both sides of one end. The hook end of the hook-plate complex has a threaded hole 3, which can pass through the locking main nail 7, and the locking main nail 7 contains a hollow hole 9, which can pass through the drilled Kirschner wire 10. There is a thread 8 at one end of the locking main nail.

[0021] The acromioclavicular joint dislocation fracture surgery is carried out in the beach chair position according to the surgical routine, and the towel is routinely disinfected. With the acromioclavicular joint as the...

Abstract

The invention discloses a hook plate complex for locking an acromioclavicular joint, relates to an internal fixing device used for treating an acromioclavicular joint dislocation fracture and a clavicle distal end fracture, belongs to the technical field of medical facilities of departments of orthopaedics, and mainly solves the treating problem of the acromioclavicular joint dislocation fracture. The hook plate complex for locking the acromioclavicular joint is composed of a hook plate complex body, locking screws, a locking main nail and a hole drilling kirschner wire. Three grooves with threads are formed in one end of the hook plate complex body, and two to three locking screws can be installed according to the condition of fracture fixation; grooves are formed in two sides of one end of the hook plate complex body; a hollow hole is formed inside the locking main nail, and the hole drilling kirschner wire can pass through the hollow hole; the other end of the hook plate complex body is provided with a thread; a hole with a thread is formed in the hook end of the hook plate complex body. The structure is simple, the operation is convenient, the fixation is firm, healing of the fractures and healing of ligaments are guaranteed, and a basis is provided for recovery of an acromioclavicular joint function.

Description

technical field [0001] The invention relates to an internal fixation device for treating acromioclavicular joint dislocation fractures and distal clavicle fractures, and belongs to the technical field of orthopedic medical equipment. Background technique [0002] The acromioclavicular joint participates in the flexion and extension of the shoulder joint, and the fracture and dislocation of the acromioclavicular joint, especially for type III injuries, due to the complete rupture of the acromioclavicular ligament and the coracoclavicular ligament, the distal end of the clavicle is completely displaced. Due to the gravity of the shoulder Sagging, conservative treatment is not effective, often requires surgical treatment, repair of ruptured ligaments, and fixation of acromioclavicular joint dislocations and fractures. At present, there are many methods for the treatment of acromioclavicular joint dislocation fractures, such as Kirschner wire tension band fixation, internal fixa...
