What is the largest non-spine bone metastasis you would be willing to treat with SBRT?

Is your size limit a function of OAR dose? If yes, is there a volume of bone that you will not exceed regardless of no dose-limiting OARs?

The size or volume per se is not a limiting factor for SBRT. Doses to OAR (parallel and serial organs) are the most important factor. I have treated large bone metastases with ablative radiotherapy (SBRT or hypofractionated IGRT) without issues.
