A sad story I've heard (and felt!) way too often! I feel your pain!
I bought a new KDX after 19 years without being on a dirt bike, and broke my collarbone in 2 places the first weekend riding (June 2). Same side I broke 20 years ago. Having just gotten over this ordeal, I'll pass on some of what I learned:
- As you have found out, the collarbone is one of the easiest bones to break. It is naturally curved in a slight 'S' shape, and a force/impact from the front, side, or back of the shoulder will be transmitted to the CB, and can break it easily. If hit at the right angle, you can break it going 5 MPH.
- Unfortunately protective gear can only prevent 2 of the 6 ways to break it. I am also now wearing the PCS neck brace. Don't worry, you won't even notice this thing once it's on. This may help prevent the bottom of the helmet from digging in and breaking the collarbone (and other neck trauma). Chest protectors don't do a whole lot. I am seriously considering hockey pads for better shoulder protection for front and side impacts. Like they say, dress for the crash, not the ride!
- The ortho docs typically just give you a sling, and say take it easy. Research has shown that the figure-8 clavical strap does not help the bone heal any better, but I wore one 24x7 as tight as I could bear. I have the scars under my arms from the raw, open sores it caused. I wore a sling and figure-8 for about 4-5 weeks, and the figure-8 only for a total of 8 weeks. I wanted the shoulder pulled back as tight as possible so that the 3 bone fragments would be as aligned as possible. I also felt it helped to keep the pieces of bone from moving around and grinding together. Originally the bone was in a figure-Z shape, and now it's pretty aligned. I think if I just wore the sling, I'd have a shortened, drooped shoulder.
- Age works against you (I'm 38). There are a lot of major blood vessels and nerves that run under the collarbone. If the break has caused damage to these (mine did), there will be less blood flow to the area, and hence the bone "glue" will not form as quick or as good. The nerve damage will heal over time. My shoulder is still numb at 4 months out, and the doc said it may take a year to fully come back.
- After 2 months, the x-rays weren't showing much signs of bone growth. Some "glue", but nowhere near calcifying. I told the doc that I want to start riding again in another 4-6 weeks, and she prescribed a bone growth stimulator. Normally insurance won't approve this device unless there is a malunion (no bone growth) after 3 months, and some make you wait 6 months ! The device I got cost $4,800, and it has 2 electrodes that attach on either side of the broken bones. A 9-volt battery powers a little cell phone sized device that attached to your belt, and you wear it 24x7 for 3 months. I started wearing the device at 8 weeks out, and I think (and the x-rays confirmed) that it really accelerated the healing process. I rode very easily at 13 weeks out, after wearing the device for 5 weeks, and although I could feel some stress soreness around the break, it was fine. I just rode a very intense 2 1/2 days up in the U.P. (at 16 weeks out), and I did some things that I thought would have re-broke the bone, but it didn't. I'm still very weak in the shoulder muscle, and have only about 75% range of motion in the shoulder, but I feel that without the bone stimulator, I wouldn't have been able to ride (or would have re-broke it!). See if your ortho can prescribe one for you ASAP. My ortho got me one so I could start wearing one, but post-dated the insurance request so that it would be approved according to their requirements. If you do get one, wear it religiously. It's kind of a pain, but a walk in the park once you get out of the sling/clavical strap. Dick Burleson was part of the group I was riding with in the U.P., and he broke his right collarbone in 4 places 3 weeks ago. He is also using the same type of bone stimulator (made by Ortho Pak). He broke his left collarbone 3 years ago, and also used the bone stimulator to heal then, and had great results. Aside from the cost of the unit, the other big rip off is that the device automatically stops working after 200 days of use, so you can't really re-use it.
- Do a search in the Training / Nutrition / Injury forum. There is a lot of good advice, and if nothing else you won't feel alone. Compared to some of the MX-induced injuries posted there (along with graphic photos!), a collarbone is relatively minor. It's painful because it can't be set, but it's not a lifelong injury like a blown knee or busted ankles.
- Because of all the nerves and blood vessels that run along the collarbone, orthos don't like to do surgery with plates and screws because of the potential of complications (mostly permanent nerve damage). The plates and screws do align the bones, but because the skin is so thin above the bone, it has a tendency to stick out and rub (although they can eventually be removed). There is a new procedure that you should seriously look into. It is performed by a doctor out of Duke University, and is called the Hagie Pin procedure. Check it out here:
http://www.medmedia.com/orthoo/5100.htm. I wish it would have been recommended by my ortho, but she would suggest it only in extreme cases. A rod is screwed in through the length of the bone, and a nut is tighted to pull all the pieces together. This allows the bone glue to form and set quicker, because the bones are snug tightly together. And they aren't "free floating" around anymore.
Hope this helps! Stick it out, it does get better. You won't be able to ride this year, but get strong for next season. In the meantime, there is a ton you can learn on this web site. Feel free to shoot me any specific questions.
