Up in the top right corner, you can see that this 39 year old woman was only 49 inches tall. She had osteogenesis imperfecta, but not osteoporosis. In persons shorter than 5 feet, the DEXA measurement gives a misleading low value because it can only measure in two dimensions.

You can calculate the BMAD (using the new BMAD calculator on this web site). This shows that her T-score at the spine was actually normal at -0.85. She also had a normal forearm measurement. The hip BMAD could not be calculated because there were rods in the femurs.

Another interesting point here is that patients with osteogenesis imperfecta have brittle bones but not necessary porotic bones. She had many fractures as a child but has been stable ever since high school.
