That combined with the distorted hip is going to cause the frog to move different. S/he might have trouble making long lunges at food, shedding, or impaction. But with proper care, frogs with minor scoliosis can still live long, healthy lives.

You can not cure MBD, but you can lessen it and prevent further damage through proper supplementation. Dust his/her food with calcium with D3 three times a week (every other feeding) and with vitamin once a week (not on the same night as calcium). Keep a close eye on him/her and watch for any other symptoms that may arise. Please keep us posted.
One problem, my frog was not like this until I posted this thread.
