Dislocating a shoulder when punching was crazy to me until last night during practice when I threw my shoulder out. It wasn't a full or even partial dislocation but it was enough to help me understand the mechanics of such an injury and why one of the students is complaining of shoulder pain when throwing punches. Most of us aren't at risk for this because we are either too tense or tense enough.
There are 2 types of mechanics that will literally cause you to punch your arm off. Both require that you are over relaxed when throwing your punch. This means that places that should be tense aren't. It also requires that you punch in the air, so I don't think it's likely to happen if punching a bag, as the bag will stop the forward motion of the arm as the shoulder leaves the socket.
The first dislocation is caused by the energy from the punch exiting out of the shoulder. This is similar to the injury that beginner students get when hyper-extending the elbow during a punch. Instead of the energy leaving the fist it leaves through the elbow causing the elbow to snap. The shoulder has the same risk.when the waist turns to get the full extension of the arm. If that shoulder is too relaxed and the student is trying to get the most out of twisting the waist to extend the range of the punch then it is possible to dislocate that shoulder when if the energy comes out through the shoulder.
The second dislocation is caused by weak shoulders. By weak shoulders I mean the connection of muscles, tendons, and ligaments that help connect your arm to your shoulder as well as the connection it self. Tension in this area will keep the arm from flying off. Being too relaxed in this area will cause your arm to shoot off. Even though my shoulder is screwed up at the moment, I think the muscles in my shoulder prevented the injury from being worse. I can actually feel which muscles were damaged because they are sore and not in a good way. The tendons in my elbow are also sore.
My injury occurred because I relaxed that connection before my punch ended. I had just finished doing 800 punches + kettlebell workout and on my last punch I totally relaxed my arm while my punch was in motion and the force from the punch pulled my arm out. Normally, we engage the muscles in the shoulder which keeps this from happening. For me, I have thick shoulders from years of running track and I think that's what kept my shoulder from dislocating.
I have a student that complains of shoulder pain all the time, and now I understand why. She's one of those stretchy people would have flexibility without trying. Hopefully this information will be helpful to someone.
