Abstract: A bone implant system may include a plurality of bone anchors, a superior rod attachable to a superior portion of a bone via the bone anchors, and an inferior rod attachable to an inferior portion of the bone via the bone anchors. The superior rod may have a superior end, and the inferior rod may have an inferior end. The superior rod may telescopically engage the inferior rod such that a cavity is present within at least one of the superior rod and the inferior rod and such that a length of the combined superior and inferior rods, measured between the superior end and the inferior end, is adjustable. The cavity may contain a micropump and a chamber. The micropump may be configured to expel fluid into the chamber to urge the length to increase.
