Case Study: The Mystery of the Brittle Bones Mr. Jones, a 65-year-old man, has been experiencing increasing fragility in his bones. He reports several fractures over the past few years from minor falls. A recent bone density scan revealed significantly reduced bone mass. Blood tests showed normal levels of calcium and vitamin D3. However, further analysis indicated elevated levels of parathyroid hormone and increased osteoclast activity. Histological examination of a bone biopsy showed a decrease in the thickness of the lamellae in his osteons, but the collagen fibers appeared structurally normal. Considering Wolff’s law, if Mr. Jones reduces his physical activity further due to his fear of fractures, what would be the MOST likely long-term effect on his bone density?
