From: Elastic intramedullary nailing and DBM-Bone marrow injection for the treatment of simple bone cysts
We arbitrarily employed a ratio to ascertain the severity of a simple bone cyst. The extent of the lesion on the longitudinal axis was divided with the normal expected diameter of the long bone at the site of the lesion. The presented in this study method of treatment has been performed in large unicameral bone cysts that occupied more than 2 times the physiologic diameter of the long bone at the site of the lesion.
