In some embodiments, provided is an apparatus including a first elongated member, the first elongated member including a distal end and a proximal end. The distal end of the first elongated member is coupled to a first bone portion during use. The apparatus further includes a second elongated member including a distal end and a proximal end. The distal end of the second elongated member is coupled to a second bone portion during use. The proximal end of the second elongated member comprises a surface that is shaped complementary to a surface of the proximal end of the first elongated member. The apparatus still further includes a locking mechanism coupling the proximal end of the first elongated member to the proximal end of the second elongated member. The locking mechanism is adjustable from an unlocked position to a locked position such that, when the locking mechanism is in the unlocked position, the first elongated member is angularly movable relative to the second elongated member, and when the locking mechanism is in the locked position, the complementary shaped surfaces of the first elongated member and the second elongated member are directly connected and the relative angular position of the first elongated member and the second elongated member is substantially fixed.
