ANATOMY

The stapes is the smallest bone in the body. It consists of a capitulum (head) which articulates with the incus, a neck, two crura (anterior and posterior) and a footplate. The head neck and crura form the stapedial arch.

The stapedial footplate becomes fixed in otosclerosis, a very common cause of conductive hearing loss.
