I believe this is called a Pathological fracture because it is a fracture resulting from a pathological condition already existing within the bone ie. osteoporosis.
In the United States, there is no such standard, directive, advice, or really any point to suggesting that patients with osteoporosis should use a wheelchair during cold weather! Or anytime at all! Osteoporosis is a loss of bone calcium. This makes bones brittle, easy to fracture if the person falls. But this is NOT arthritis! You can have osteopenia or osteoporosis without having pain. You can have it and not know until AFTER you break a bone--and you do not need to fall to incur a fracture. Further, weight-bearing HELPS build bone. So, no, a wheelchair would not be recommended unless the person could not stand and walk.
secondary osteoporosis
Yes because It has a backbone. that is the reason for a hedgehog being a vertebrae if it did not have a backbone it would not be a vertebrae.
The knee joint does not contain vertebrae.. that would be the spine.
Individual vertebrae make up the spinal cord.

A superior endplate insufficiency fracture is a type of spinal fracture that occurs in the vertebral body, specifically at the superior endplate, often due to weakened bone density, such as in osteoporosis. This fracture typically arises from low-impact stress or trauma that would not normally cause injury in healthy bone. It can result in pain, decreased spinal stability, and potential spinal deformity. Diagnosis often involves imaging studies, and management may include pain relief, physical therapy, or surgical intervention in severe cases.
