Embodiment 1
[0040] The first acromioclavicular hook plate of the present invention that can repair the coracoclavicular ligament, refer to Figure 3-5 , the acromioclavicular hook plate is provided with a hook plate 1, a nail hole 2, an acromion plate 3, a first suture tunnel 4, and a second suture tunnel 5, and the nail holes 2 are distributed on the top of the hook plate 1, The nail hole 2 is through, the nail hole 2 is a threaded nail hole, the first suture tunnel 4 is arranged on the front part of the hook plate 1, and the second suture tunnel 5 is arranged on the hook plate 1. At the rear of the plate 1, the shoulder plate 3 is arranged on the right part of the hook plate 1, the shoulder plate 3 and the hook plate 1 are integrally formed, and the shoulder plate 3 and the hook plate 1 are in a “Z” shape , the center of the first suture tunnel 4 is 2.0cm away from the connection between the hook plate 1 and the acromial plate 3, and the center of the second suture tunnel 5 is 3.5cm awa...
Embodiment 2
[0044] Clinical trials were performed using the acromioclavicular hook plate of Example 1, and compared with the clavicular plate and the Endobutton plate with loops.
[0045] In clinical trial, 300 routine patients were carried out comparative experiment, 100 routine patients used clavicular plate, 100 routine patients used Endobutton belt loop steel plate, 100 routine patients used acromioclavicular hook plate of the present invention. After 3-18 months of follow-up, the following data were obtained:
[0046] (1) Among the 100 patients who received clavicle plate, 10 cases had dislocation after internal fixation removal, 7 cases had incision, and 2 cases had these two complications at the same time;
[0047] (2) Among the 100 patients who used the Endobutton plate with loops, 13 had stress fractures;
[0048] (3) Among the 100 patients who used the acromioclavicular hook plate, there were 2 cases of dislocation after removal of internal fixation, and 1 case of stress fractu...
Embodiment 3
[0051] The second acromioclavicular hook plate of the present invention that can repair the coracoclavicular ligament, refer to Figure 6 , and the difference from Embodiment 1 is only that: the shoulder lock hook plate is also provided with a locking groove 6 and a locking device 7, the locking groove 6 is arranged on one side of the nail hole 2, and the locking device 7 is arranged on Locking slot 6.
[0052] The advantage of this embodiment is that the screw can be effectively fixed by using the locking device, and the displacement of the screw can be avoided after a long time of fixing.
