Muscle atrophy depends on the amount of stimulation of the muscles themselves. Even slight usage maintains a large percentage of muscle mass even when it is minuscule compared to standard usage. It has been proven in people who are in comas, etc, that any stimulation of the muscles whether thru 3rd party manipulation or even shock therapy can prevent serious atrophy. So as long as you arent lying in bed like a vegetable, your recovery time shouldnt be too terribly extensive in theory.
Did you know that people with amputated hands... when they IMAGINED flexing their hand... it prevented atrophy of the forearm in a controlled experiment. LoL. Crazy.
