Thank you for sharing your excellent question. Assuming you are otherwise a good candidate, and your spine surgeon clears you, there should not be a reason you can not pursue a tummy tuck procedure. Hope this helps.
Arthritis and other spinal conditions are ok to have a tummy tuck provided post op posturing are not an issue.Usually, you will be flexed at the waist for several days afterward, which may or may not temporarily aggravate your symptoms. Clearance from your spine physician would be helpful preop.An exam and consultation with a plastic surgeon is recommended to further discuss your options and expectations.
