Can you replace the bottom of a flashes hot shoe if it breaks off?

I have a Canon Xsi Rebel SLR Camera and i have a flash that I can attach onto it. Clumsy me let the flash drop in my purse a few days ago and about 1/4 of the side of the plastic of the hot shoe broke off. This is a bas explanation i know, but the flash does still work, it's just unstable when i mount it on my camera. Is there anyway I can have just that bottom portion replaced?
