If it broke in 2 separate pieces then there is nothing you can do but learn the next time and hope it's smoke-able. That plant will go into recover mode and the THC production will slow.

If it is NOT snapped in 2 then you can wrap moist Cheese Cloth with some type of rooting powder and wrap the stem and pray. It may recover in about a week as long as it can still get nutrients through the cell walls.
