Radiology of rickets, osteomalacia and hyperparathyroidism.

In osteoporosis, the amount of mineralized bone is diminished, but the remaining bone is of normal quality. In rickets and osteomalacia the trabeculae are irregularly mineralized, a feature reflected in the X-ray image. In hyperparathyroidism there is generalized and focal bone resorption leading to demineralization and poor definition of bone on the X-ray.
