Are there attorneys who help individuals who are incarcerated? The lack of medical attention caused my husband to have two back surgeries.

The answer is yes.  Search for attorneys in your area (or, if your husband is being held somewhere else, then in the area or state where he's being held) who do civil rights or federal tort claims act cases.  Searching for both or either of those terms should turn up a group of lawyer who you can talk to about your husband's case. I wish you and him the best of luck.
