@windyshores ,
you may have been wise about kyphoplasty, but it is usually the vertebra above or below that crack--below because of the weight and above because of increased lack of flexibility. That painful instability is what drives the fractured to seek kyphoplasty.
When you first mentioned the density/flexibility pain issue, I thought it was, perhaps, in the joints. But, though not human (mostly rats), microscopy tests are telling the story about the difference between modeling and remodeling. In remodeling the osteocytes imbedded in the bone respond to our experience of the muscle pulling on the bone, as well as impact forces. This response realigns the spicules in an isoform most favorable to protection during activity. Protection, but also (I would suggest), comfort. Modeled bone provides fracture protection without the finess of remodeling.
Most of these "findings" are from pathologists in labs where no person would want to be the specimen.
"Finding," "suggestions," "possibilities," can only be cloying when we want, need answers.
