摘要： An expandable orthopedic implant includes a casing pipe, a shaft, a first expandable element and a first link lever. The casing pipe has a first opening, a second opening and an axis passing through the first and second opening. The casing pipe sheathes one end of the shaft, and the other end of the shaft has a top portion disposed out of the first opening. The first expandable element has a first terminal pivoted on the casing pipe and a second terminal. The first link lever has a proximal end pivoted to the top portion and a distal end pivoted to the second terminal. When the top portion is driven moving away from the first opening along an extending direction of the axis, the first link-lever can be pushed by the shaft to enact the second terminal moving away from the axis along a direction perpendicular to the axis.
