Your doctor informing you your fracture is healing nicely "may not" have anything to do with you having osteoporosis as far as the doctor knows. You haven't provided enough information. However, my orthopedic surgeon LOOKS at the xrays and can SEE the bone demineralization which tells us all that I need to be on bone meds. Why didn't he tell me that years ago? Maybe he made presumptions that the other doctors were dealing with it - afterall, he is just a surgeon! 😉 And maybe now that he went in to find soft bones like paper he is more attentive. I don't have osteoporosis. Like I said - The DEXAs are a general thing. Because I have had all my large joints replaced they have to use smaller ones like my wrists. And my wrists happen to be VERY strong because I lean on them tons for work. So the DEXA with the TBS is the way to go. And now that I am on bone meds the CTX and P1NP over time, plus the dEXA plus the xrays tell everyone about my body.

And actually - you can see the demineralization when comparing my x-rays to each other. My surgeon showed me. They have high-quality equipment at UCSD and knowledgeable
