There have been other threads about this in the past, e.g.
http://forum.slowtwitch.com/..._reply;so=ASC;mh=25; I had an ACJ separation in the middle of this year. One thing to understand is that the diagnosis of grade isn't very exact.
http://www.internationalshoulderjournal.org/...e=104;aulast=Dearden "Rolf
et al. have noted in a series of patients treated surgically for ACJ dislocation; 55% of patients with radiographic diagnosis of grade III injuries were found to have grade IV or V injuries at time of surgery.

There seems to be very little agreement about whether a grade 3 should be operated on or not. I spoke to numerous surgeons before and after having surgery on mine, and some were of the opinion that surgery would generally improve the outcome for overhead movements such as swimming, while others thought that it wasn't worth it. However, there is more consensus about grade 4, which is why it is relevant that in patients treated surgically, 55% who were thought to be grade 3 turn out to be grade 4 or 5. This suggests that anyone who is diagnosed as grade 3 needs to consider the possibility their injury is in fact a grade 4 or 5, in which case there would be a much stronger case for surgery.
In my case, I could really feel the clavicle digging into my shoulder when I raised my arm overhead, and the shoulder surgeon I saw who went through the options didn't suggest this problem would ever go away. Excising the end of the clavicle can solve this and other problems and is a very straightforward arthroscopic surgery. But the crucial thing he explained to me is that fundamentally there are two ways you can go with surgery. You can do something soon after the accident, up to around 3 weeks, to hold the clavicle in place, and this will allow the ligaments to heal back together, putting your shoulder back to more or less how it was before the accident. Or later on you can perform a reconstruction. The main options for the immediate option are tightrope, clavicle hook plate or surgilig, all with their pros and cons. There are many studies you can read:
http://www.ncbi.nlm.nih.gov/...=clavicle+hook+plate The surgeon I spoke to refused to consider the tightrope as he found the failure rate unacceptable. The benefit of tightrope is it can be done arthroscopically, so less cutting of flesh, and it generally allows more movement while healing is taking place. This is important, as any period of reduced movement of the shoulder causes problems and is not easy to reverse. The downside is it is more prone to breaking before the ligaments have healed enough to hold the clavicle in place. There are variants on the tightrope such as a twin tail, or putting two separate tightropes in to try to reduce the risk of failure. The preferred option for immediate fixation of the surgeon I saw was the clavicle hook plate, and that is what I had done. They put a plate in which is screwed to the clavicle, and it hooks under the bone next to it. It sounds like this is the surgery you have been offered. It requires a fairly large incision, mine is 7cm. The plate is left in for 3 months, then removed. It can be removed by cutting around the original wound, so you only have one wound at the end of it, but apparently different surgeons have their own preferred ways to do it. I suffered very badly with the plate in, I could basically do almost nothing in the time it was in, and got about 2 hours sleep per night due to the pain. I had very little movement with it in, so my shoulder seized up badly in that time. Apparently this is quite variable from person to person, and there is no way to predict how it will affect each person in advance, some people aren't bothered much by the plate at all. However, as soon as the plate was removed and the immediate effects of the surgery had healed and I was able to start using my arm again, the improvement was very rapid. I'm not back to full function yet, but I can train in the TT position, and I can swim with technique that is pretty close to pre-accident, this is 4-5 weeks after being allowed to start using my shoulder again after plate removal. The problem everyone has is they can never know how it would have progressed if they had gone down a different route. If I could go back in time and try another approach I'd be pretty keen on having two tightropes put in instead of the hook plate, given how badly the hook plate affected me. And not having a 7cm wound would be nice. It would of course be interesting to know what it would have been like without surgery, but there is only a window of a few weeks to make the choice, so you can't try that option then go back and have the surgery if you aren't happy with the end result.
Which brings me to the second fundamental surgical approach, which is reconstruction. So this is for people who are outside the window for the ligaments being able to heal. Surgilig was the preferred option of the surgeon I saw, and he was willing to let me choose to complete my cycling season, see how it all went, and if I still wanted surgery, put the surgilig in, which is a synthetic replacement for one of the ligaments that is then left in the body for ever to hold the clavicle down towards the scapula. I just couldn't escape the feeling that it would be much better to heal my own ligaments rather than have something alien in my body for ever more. There are numerous other possible approaches to reconstruction. The surgeon who ended up performing my operation and has handled all my post-operative care, when I mentioned that this option had been considered, basically thought you'd have to be mad to choose it over healing the ligaments in the initial window after the accident.
There's no doubt that the hook plate surgery can be a major undertaking for the patient. You may or may not go through hell in the time the plate is in there. The studies are very ambiguous on whether it is better than no surgery, but from my experience I would say that the way the outcomes are measured is stacked against the surgical option. For starters, they look at timescales that are quite short. There is no doubt at all that the surgery will set you back in the short term compared to no surgery. Comparing function at 3 months, for example, is a nonsense, of course you'll be worse off with surgery. And the way they assess it, with the Oxford Shoulder Score, is also a nonsense, in my opinion. I have filled in an Oxford Shoulder Score questionnaire, and it asks you whether you can do activities such as carrying a shopping bag, or hanging up clothes. What I wanted to know is which approach would get my swimming performance back closest to where it was pre-accident. There is no research that has studied function by that sort of measure.
