Marine Cabirou has shared on social media that she has broken three vertebrae after a big crash during her race run.
The French rider is still coming back to full speed after breaking another vertebrae
during the offseason but she has now broken her T3, 4 and 5. Currently Marine doesn't know when she will making a return to racing but is on her way back to France for more exams.
|Leogang race result = 3 broken vertebrae.|
Not the result I expected from Leogang this year. I felt good on my bike, finally started to be myself! I gave it all, but …
I had a huge crash in final in the stumps section and crash directly on my back … like you can imagine the result is bad, it’s hard to accept but it’s part of the game!
After broken T12 this winter, yesterday I broke 3 vertebrae T3, T4 and T5! I know how the back injury are complicated, so I will take time to recover well, I couldn’t tell you when I will be back …
I’m actually on my way to be back in France and I will do more exams tomorrow… I will keep you update when I know more about my health and my recovery process !— Marine Cabirou
We wish Marine all the best with her recovery and hope she is back on a bike soon.
"Football is 90mins of pretending you're hurt. Rugby is 80mins of pretending you're not."
It's a shame, really
I figured there had to be a nonracist explanation, thank you.
Nobody is cheating in cycling are they?
*Cough* doping *cough*
When people like you stop trying to make everything about skin colour, the rest of us will be better off.
I know you haven't, but why don't you think for just a second about what jemscott REALLY meant when they said "...mtbings demographic is the polar opposite" to football's massive diversity?
How odd is it that you are attacking me because in your mind I'm making this all about skin color but you haven't said a peep about the original poster who actually brought up wjere people are from which has always been racists' code for pointing out skin color.
I informed you countries such as Italy, Brazil, Uruguay, Spain, Greece, Argentina, etc are populated by a lot of people with complexions ranging from fair to dark.
Now you're babbling about Africa and the past....dude, you've got a screw lose.
Get well Marine.
Those are essentially all yours and jemscott's words, go ahead, contradict them.
Just a matter of time folks with these speeds getting faster and faster. Hate to say it, but it’s gonna have to take a really, really bad incident for stuff to become mandatory.
Vertebral fractures come in all sorts of variations. They are as minor as transverse or spinous process fractures to essentially unstable dislocations of the segments involved. On the CT scan Marine posted, there is a disruption of the anterior column of the upper thoracic vertebrae. These typically happen with forward bending (flexion) and compression, such as when your head strikes the ground and your upper chest crumples with it.
Modern "back protection" does not adequately protect against this mechanism, as they allow bending (flexion and extension) and rotation, the extremes of which lead to the most common spinal injuries. That also doesn't mean they don't offer any protection. If you were to fly over the bars and land directly on your back, it could theoretically prevent "injury" to the back, but that is not the mechanism by which the vertebral column typically fails. Unfortunately, it is the physics of the sport and the resultant forces that happen when crashing.
A true "back protector" for the fracture she had is called a CTLSO. It has an anterior and posterior restraint. Sometimes we give these to patients, but generally for these upper thoracic compression fractures, they are so restrictive and limiting, that we usually just say avoid bending and twisting until it heals. If you google what this is, you will see how impractical of a device this is to employ while riding.
I’m only now starting to recover properly from this epic slam
All the best to you Marine, & a speedy recovery
Sure. The short answer is there is not enough "strong" evidence at the present time to support that neck braces prevent or reduce the risk of cervical spine and/or upper spinal cord injury.
Relative to the back protection, there is at least face validity in the construct. That is to say, it appears to limit the type of range of motion that can lead cervical spine injury. However, to adequately test the efficacy of a neck brace in a robust study design would require a sufficiently large number of participants. They would be randomly chosen to wear a neck brace. They then would incur the same cervical spine injury, of which there are numerous ranging from very mild, to moderate fracture without neurologic injury, incomplete neurologic injury, and complete neurologic injury. Then there would have to be a statistical analysis to evaluate the risk reduction between the brace and not braced group, accounting for many confounding variabilities. This is not a feasible study design in vivo to evaluate the efficacy of a neck brace.
The leader in neck brace design, Leatt corp. conducted a study using computer simulation and surrogate models. They evaluated multiple parameters in specific loading events that that place the cervical spine at risk of injury, such as flexion-compression, extension-distraction, and axial loading. Overall, they demonstrated a reduction in the forces transmitted to the surrogate model and within their computer simulated model for these simulated events.
The primary limitation of the study is it has not undergone rigorous peer review. Their methodology for the biomechanical work has not been evaluated by outside experts in the field. It is easy to discount the value of that, again looking back at the face validity of the design, but for me personally, in an area as complicated as the kinematics and pathophysiology of the cervical spine, the study should be evaluated in a reputable biomechanical journal. Any question of methodology, limitations/bias, and the conclusions would then be addressed independently by those who conduct this type of research.
Where the questions remain is can this work, which is purported to demonstrate reduction in the possibility of neck injury using automotive standards be sufficiently extrapolated to the downhill mountain biker. As in, what is the “clinical” significance? How does the variability of helmet design, fitting of the brace, the role of the dynamic restraint of muscles, variability in bone density and the static ligamentous restraints, the possible negative implications of restricted range of motion with a brace all contribute to cervical spine injury? It appears they did their best given the current technologies, but unfortunately, this is likely too difficult to simulate to the point where such a generalization can ever truly be made.
I do applaud Dr. Leatt and his team, regardless of financial motivation, in tackling this very complicated problem. None of this should be interpreted as the modern neck brace does not work to do its intended job. It’s just my medical training and research background that would like to see more robust critique of the data and less reliance on marketing with an incidence survey which is rife with limitations to support their use. Fortunately, the rate of cervical spine injury leading to devastating neurologic injury is very low. It is my opinion, that this sport can be done in risk mitigated manner by exercising extreme caution when riding. This is where I believe the true value is in preventing these injuries.
Also wanted to add, that there is a Austrian company called adamsfour that is engineering a back protector to prevent torsion fractures, but I don't know why I haven't seen a product from them for sale yet, despite that the company exist for a couple years now.
Same goes for helmets and concussions. There is currently still no helmet technology that is scientifically and independently peer reviewed to prevent or reduce concussions. Best bet unfortunately is to ride within one's abilities and only take very calculated risks.
Your point re risk mitigation is one I've thought about often too, but more from the perspective of skills training and learning how to fall. I look back on my years of throwing myself down downhill tracks with some amount of disbelief. I wouldn't try to learn to ski-jump without coaching, so why I tried probably higher consequence things, on a bike, with no more instruction than a few bike magazine articles I do not know (well, I probably do, optimism bias of the young and all that).
Nowadays I work hard to understand the theory, then build the practical skills based on that, but that's probably just me getting old, slow(er) and knowing I don't heal fast anymore.
I don't think so, some riders especially the top pros ride those race tracks more often on one day than I do my local dh trails in multiple days. They study every stone so to say. I think it was thannee who sayd in a interview on race day there is no section where a pro is still scared or unsure, because that would only mean he/she didn't train the track enough.
Are there some slips here and there even before something like that drop, sure. But pros are used to that kind of situations and have hundreds of similar good outcomes on their shoulders.
It probably also depends on how much a track has changed since their last run before the race (rain). Anyhow, to be sure we'd need a qualitative study to gather the thoughts of racers on this.
UCI only mandates a full face helmet.
Some (truly idiotic) riders stick cardboard on their back to trick the marshalls...
"MTBings demographic is the polar opposite hence the higher standards (in some ways) that we try and maintain."
What exactly do you imagine the polar opposite of massively diverse to be? And you see no problem them ascribing the alleged higher standards they supposedly posses as being a by product of their polar "opposite-ness"?
This crap is the same codified dog whistling that KKK types have been spewing in America for centuries. Maybe you are just unfamiliar with the dynamic at play.
I do wonder if a better back protector would have prevented the injury, but hard to say from the video and pictures. It seems a lot of WC Pros wear protection begrudgingly. Personally, I've been saved by my back protection too many times to be comfortable doing gravity riding without it.
As longs as the mud isn’t too tacky its pretty easy to reclip. I feel like its definitely easier with some shoe and pedal combos than others
It is almost always via force introduction on the head or arse. In general big injuries are mostly quite far away from the point of impact. So protection helps very little (helmet and knee do wonders, though). Training (strength and flex), risk management and correctly tuned equipment are far more effective. MX/SX guys know that, MTBers on PB don‘t know shit. So imo mandatory back protection would be quite useless. I wonder, what really happened in her case, healing vibes for sure. Sometimes it is just bad luck.
It’s a nasty injury. Godspeed Marine
I hope Marine gets to full health soon. Gutted she's can't race again, I rooted for her as well
Edit: @commental I realize you are in agreement, didnt mean for this to a rebuttal towards you.
Good Grief !
This woman is a beast for getting back up, that was a beast of a crash. Heal up! Gonna miss watching her ride for awhile. I’ve of my favorite ladies.
After broken T12 this winter, yesterday I broke 3 vertebrae T3, T4 and T5!"
Sounds like due to impact?
Maybe some really good back/spine protection?
Didn't learn anything first time?
Back protection only helps against impacts, not at all against (over)extension.
It also appears to me, more and more top tier riders compete with back protection (Bruni, Iles, Pierron,...).
And Bernard crashed exactly at the same place during the quali as Marine.
Dog bless &y &erson for llidding up and tearing it up.
Particularly back injuries from compression of the spine, collarbone fractures and dislocated shoulders.
Not a lot of carnage like this for the real riders tbh anyways
But her back wasn´t even dirty (just watched the replay), so it was the overextension. Against which afaik no known protection equipment helps.
