@annie1 The problem you are asking about is a fracture near the facet joints in a vertebra bone. That bone is also connected to back muscles that can pull on the bone and add some force to the fractured area and if I recall correctly from your posts, you also have osteoporosis. That is a medical question. You can consult your doctor who treats the osteoporosis or any spine specialist you have seen. Doctors aren't always aware of how MFR works, but it's physical therapy. I found a link about a PARS fracture and in skimming it, it talks about rest and healing and some surgical options. We are all patients here sharing our experience, but no one can advise what is best in your circumstance or what risk there may be. You need a medical expert to answer that for you. Perhaps MFR can be done in other areas avoiding the affected spinal area, but a doctor needs to answer what is best. Here is the link.
