Where this comes from

Abstract

Accessory ossicles about the elbow may occur more often than the literature would indicate. These bony ossicles frequently cause problems with misdiagnosis. The os supratrochleare dorsale, because it gets traumatized by elbow extension, may require removal to relieve pain, locking, and decreased range of motion.
