As far as you are concerned, it's still difficult to judge if you haven't seen the film, because you only said the angle, how much the angle is, and how is the counterpoint?

Guiding opinions:

If the alignment is ok, and the angle is below 15 degrees, then the external fixation is also ok, that is, the inverted 8-character fixation, and the surgical effect is of course much better, basically achieving complete alignment. But if the external fixation is done well, it will not have much impact.

Disease analysis:

Because the boy's clavicle fracture needs to be combined with his actual age, if he is a teenager, because he still has the ability to shape, if the displacement is not obvious, he can recover by shaping.

Guiding opinions:

As you said, if the angulation does not exceed 10 degree and the dislocation does not exceed one third, most of them can be recovered by plastic ability, because clavicle fracture is difficult to fix and easy to shift, so it is suggested that surgery is needed when necessary.

Disease analysis:

Hello, it depends. Most clavicle fractures can be cured by external splay fixation, but they usually heal with some deformity.

Guiding opinions:

My suggestion is that if you want the fracture to heal perfectly, you can consider surgical treatment. Don't worry, I wish you a speedy recovery.
