An expandable implant includes a lower support; an upper support pivotally coupled to the lower support and including a control channel; and a control assembly. The control assembly includes a control shaft coupled to the lower support and a control member coupled to the control shaft and configured to move along the control shaft. The control member includes a base member and a pivot member pivotally coupled to the base member, the pivot member configured to move within the control channel. Movement of the control member along the control shaft causes the pivot member to pivot relative to the base member, and the upper support to pivot relative to the lower support.
