Scruggs, 65, said he suffers from a disease that causes his fingers to contract.
His physician, Dr. Cooper L. Terry, said in a sworn statement to the court that without immediate surgery, Scruggs' condition will progressively worsen and affect his long-term recovery and outcome.
Scruggs tells the court he will pay for the surgery and return to the Lafayette County Jail, where he's being held, before the hearing starts Monday.
At the hearing, Scruggs' attorneys will seek to persuade Senior U.S. District Judge Glen H. Davidson to vacate their client's 2009 conviction to improperly influencing a judge presiding over a lawsuit against him.
Scruggs continues to serve prison sentences on that conviction and one in 2008 to attempting to bribe Circuit Judge Henry Lackey.
