Eligibility for Waiver of the Three- and Ten-Year Bars
The waiver applies to intending immigrants who can demonstrate that if the waiver and visa are not granted, their U.S. citizen or lawful permanent resident spouse or parents would suffer extreme hardship. But extreme hardship can be difficult to prove - it means more than the hardship that any family member would feel upon facing separation due to denial of a visa. Medical, financial, educational, and other factors are taken into account.
The article goes on to say that you will need the help of an attorney to get this Waiver, but it is not impossible.
Contact a US Immigration Attorney, and be prepared to document in extreme detail your husband's injury and recovery. You might have a case.
