If this is anything to go by...
Eva30corsetlover I had scoliosis and had to wear a corset during puberty... In the process I built a special relationship with corsets. And I wear one permanently.
...you should chat to your prosthetist and get something ahem "supportive" custom made for you. Alternatively HW Design in Vienna have some very restrictive corsets, but given your medical history you should be very careful tight-lacing all the time. You should definitely be going down this path with some guidance from your doc, OT and/or physio. Don't mess with your spine, you only get one.
