Unexpected kimura injury

The other night (about a week and a half ago) at training my friend was rolling with one of our partners got cauight in a kimura and we ended up hearing his arm pop. We thought is was most likely a tendon issue. After waiting for it to heal on it's own for almost he week he finally went to the doctor and found out his arm was litterally broken in to 2 pieces. with some slight nerve and tendon damage. He understands that he should've tapped sooner, but i'm thinking for rolling the kid might've been going to hard. I mean, if a shoulder injury would've occured no big deal, but the kid wasw pushing hard enough to break my friend's arm over his forearm. Have you guys ever heard of any injury like that from a kimura?? What are your thoughts?

No, cant say I have. As soon as the hand/arm is behind there back and hes past the point of defending it properly be-it grabbing the leg or gi pants I release, unless its a tournament.

yeah this was just rolling at practice. Do you think the guy would be using way more force than needed to make that kind of injury happen?

No, that's what the Kimura is suppose to do. If your question though is should he have been going full force spaz on him in a Jiujitsu setting than no, he probably should have just used the Kimura as a setup for something else like a Triangle. My opinion of course, people have different philosophies about Jiujits.

you have to understand that your friend can tap at any point in time. an inexperienced person would not know he's about to break your friends arms. for all he knew, he wasn't applying enough pressure because your friend wasn't tapping. it's both of their faults but more your friends.

** shoulder joint

That's what i'm saying is that the injury should've been to his shoulder but it broke the bone along his bicep, which confuses. I know he should've tapped, and so does he, but i'm just trying to figure out why it would've snapped there instead of fucking up his shoulder real bad.

Sound like the guy was a newb and wasn't under the elbow, which changes the fulcrum and leaverage point. But he was cranking way too hard eitherway! Flow in the gym, get it at the tournies!!!

In the wrong circumstances it might, but not knowing the position they were in makes it difficult to understand how this happened. I have a hard time believing that a guy got his arm broke from a kimura if the opponent was in a "triple threat" position (kimura, armbar, or take the back from sitting on the guys head).

@op the kimura is designed to break BOTH. The arm breaks because the tendon attachment pulls the humerus in halg (pretty sure Helio's arm broke this was against Kimura) and it is in fact a common way for an untapped to Kimura to end. Matter of fact I have seen more broken arms from a kimura than wrecked shoulders.

The hold did just what it was supposed to do, your pal, should have tapped. Matter of fact he may not have tapped becuase he has decent shoulder flexibilty, but the arm tendon/ligament-humerus connection got him anyway.

Working as intended, nothing odd.

that sucks for your friend. I avoid situations like this by tapping before pressure is applied given that I can't obviously counter the submission. People ought to swallow there pride at the gym and realize tapping is a good thing.

You can feel a joint goin. Bones just break. Shitty, but this is what we signed up for.

Thanks! this was the type of answer i was looking for. you answered all the questions. That was it i'm sure, because he does have really flexible shoulders, you had to get OMO's deep on him and what not, hardly ever tapped to shoulder locks, and then crack! Thanks man, that explains it all.

No problem. Kimura, if you can secure it, is a nice lock because it is a triple threat (humerus/shoulder/elbow) and very few people are flexible enough in all three areas for something to not go.
