An expandable implant includes a base member, an adjustable member adjustably coupled to the base member and movable between a first, collapsed position, and a second, expanded position, a control assembly including a control shaft, wherein manipulation of the control shaft causes relative movement of the adjustable member relative to the base member, wherein the base member and the adjustable member are coupled together at least in part via the control assembly such that the control shaft is rotationally fixed relative to the base member and the adjustable member, and the adjustable member is resiliently compressible relative to the base member.
