The Survivors of Symphisiotomy are calling for a redress scheme for the "inhuman" procedure they underwent without consent.
The procedure involved women having their pelvises broken before, during or after childbirth leaving many with lifelong disabilities.
The group is taking its case to the United Nations Human Rights Committee next month as part of a scrutiny into the human rights record of Ireland.
Details of the survivors campaign will be launched in Dublin this morning.
Tilda Behan underwent the procedure on April 29th 1958. She gave details to Newstalk Breakfast this morning.
She told reporter Shona Murray that successive governments have ignored their plight.
