Can you have concussive force in space?

For example, if an explosion takes place say 20 meters from me on Earth that would cause massive internal trauma due to concussive force, will the effect be the same in the vaccuum of space? Not counting heat/shrapnel of course.

Not likely. What you're talking about is damage from the shockwave that propagates through the atmosphere after the explosion. Without an atmosphere, there's nothing to propagate the shock. You may be hit directly with the expanding gas from the explosion, but this will be very weak in most situations - the damage from an explosion is caused by the energy it adds to the air, not by the amount of gas it deposits.
