Manager Arsene Wenger last week revealed the England international had suffered a "little setback" in his scheduled recovery from the injury sustained in pre-season.
"Due to a slow healing response from a fracture suffered in August, the club can confirm that Jack Wilshere is to undergo an operation to his left fibula," Arsenal said in a statement.
"The decision to intervene has been taken quickly after regular reviews by specialists, who feel that Jack's scans show that the healing process is not progressing as well as expected.
"Jack will have surgery in London in the forthcoming days. This will involve inserting a small plate in his left fibula. Jack is likely to be out for approximately three months.
"Everyone at the club wishes Jack well with his rehabilitation."
