摘要：
Unidirectional dynamic interbody fusion devices and methods of use for insertion into a patient in order to maintain a space between two vertebral bodies. A first interbody fusion device including a body member, at least one side member, and a means for moving the at least one side member relative to the central body member. A second interbody fusion device including a base member, a top member, and a means for moving the top member relative to the base member. A surgical method for maintaining a space between two vertebral bodies in a spine, including obtaining a medical device, inserting and coupling an expansion tool into an opening within the medical device, slidingly inserting the medical device into a space between two vertebral bodies； and rotating the expansion tool to move the at least one side member in a direction relative to the body member.
