Going through the recovery from a riding accident - I am having problems persuading orthopedic surgeons to operate so came up with the idea since I had a CT scan I could get a 3D printed model made. The idea is to work out the original length of the clavicle so that it can be restored to a similar length.
The 3d part is seen as this and now has gone to be 3D printed - quite exciting

That's really cool Kevin .... I hope the medics follow it through successfully.
Weirdly, the image resembles that of the planet I was born on.... ![]() Alan |

That is really good, in fact it looks just like my left clavicle use too, so if you are ordering spares can you put me down for one please ;-)
Joking aside, I'm hoping to shortly do a piece for the club mag on 3D printing, PM me and we'll discuss getting your clavicle famous if you fancy, along with bike parts and other stereo lithographic parts. Karl karl@windcheetah.co.uk

This looks and sounds fascinating Kevin, and well worth a magazine article. However I'm sure I'm not alone in craving more information. What are we actually seeing on the video? Is that your clavicle shortly after the accident, broken into two spikey pieces, or is it supposed to be like that? [You can tell I'm no doctor even though I may be married to one.]
Secondly, please tell us more about what the plan is for the model when you have it. Are you going to fit the bits together, take it to the orthopod and say that's what you want doing? Of course I could just wait until the book comes out, and the film of the book, but I'm curious (as many people will tell you). |

To be honest Andrew - should do it as an epic - it feels a bit like that to me. IT is the broken one taken from a CT scan of the shoulder. not quite how it healed (but pretty close!) The real purpose for going for the model being made is that I am looking to have an operation to rebuild the clavicle. It seems that it is extremely difficult for the medical profession to work out what the original length should be. Their best method is comparison to the other side - though as everyone will know (and they do) - you are not in reality, symmetrical. So... my idea was to use the CT scan I had - I managed to get a surgeon to extract the clavicle data from the CT scan and then they will use the info to make a model of it (3D printed) so should be life size. Then I am not quite sure - I may end up cutting it up a bit to work out how it fitted together to work out the original length or I am hoping I can do it by measurement then - hopefully it will be slightly better than guess work. (Maybe I should get two done!!!!)
I don't have a scan of a clavicle in its original form - but a google image is here It is quite a boring looking bone - I am beginning to think mine is far more interesting. Another reason fro not cutting up the model is it might be useful in working out where to cut it up to operate on. As for the film - chatting to Spielberg now . If I get this sorted out I am sure there is an article in this - depending on the outcome it will hopefully be humorous (no pun for shoulder bone intended)Finally I was wondering about getting a full shoulder model made as an art piece with the broken clavicle and shoulder blade.

Kevin,
I shattered my clavicle about 10years ago, it did look very similar to yours, I wish they would have plated it at the time, but due to the nature of the skin in that area being thin there is a big risk of infection I believe, even worst as it would be the bone that would deteriorate and once its gone... its gone! It was left to heal its self, from what I believe the ends of the bone become tacky and stick together, it would eventually find its own place and settle allowing the bone to calcify (if thats the correct term, Im not a doctor) I am now left with a clavicle with a definite over lap that is fixed in that position... think lap joint that isn't aligned correctly, with a nobble top and bottom that can be felt through the skin. A couple of years later I then dislocated the same shoulder so in a funny kind of way can testify to the strength of a healed bone. A quick note on 3D printing for medic procedures, I believe they now do Laser metal sintered titanium parts for complex hip replacements, and dental reconstruction of jaw bones. Getting closer to making me a new body if only we could do the brain transplant bit. Memo to self... give up mountain biking. I'll look forward to the film. Karl

I have some experience of 3D printing. The guy I usually work for has two FDM machines and we did a 3D printed titanium roll hoop for the Hispania F1 car. The latter amazing technology but very poor surface finish. 3D printers usually require STL files, but I can convert to this from other 3D formats. If you think I can be of assistance with your fascinating project Kevin then please say. And hoping you're fully healed soon.

As an update. Went to see surgeon with 3D printed collarbone in hand. Quite alarming really. X-ray comparison of sides implies about 10mm shortening. Model shows over 25 mm. No problem getting surgeon to believe the model. He was totally amazed with it. Not only does it mean that the length can be judged correctly. That becomes slightly irrelevant since because he can see how it looks he thinks he can unpick it and piece it back together as it was rather than the normal diagonal cut and slide it to produce more length. He was getting colleagues to look at the model.
So I would definitely impressed with the 3D printing. It has changed the treatment I am getting. Operation scheduled for mid May. So titanium strengthens after that

Its a great example of the technology. Soon we'll be printing our own fully faired monocoque streamliners...
