(Marble bone disease) In this congenital disorder of bone formation the bones are densely sclerotic.
The bones are brittle and may fracture readily, but if fractured they heal easily.
Anteroposterior x-ray of the hand of an 8-year-old girl: pronounced metaphyseal densities in line with increased sclerotization of the bones of the fingers.
There is a marked generalized increased bone density affecting all bones. There are multiple healed fractures, with a pin and plate in the left femur.
