1. An orthopedic device assembly comprising:
a threaded elongated shaft comprising:
a length;
a longitudinal axis defined therethrough; and
at least two flat threaded side surfaces extending over the length of the elongated shaft, wherein the at least two flat threaded side surfaces comprise threading extending the entirety of the at least two flat threaded side surfaces; and
one or more clamp members configured to be releasably clamped on to the threaded elongated shaft,
wherein when clamped on to the threaded elongated shaft, each of the one or more clamp members is configured for holding at least one bone fixation pin in an orientation that is non-parallel with the longitudinal axis of the elongated shaft and parallel to one of at least two flat threaded side surfaces of the elongated shaft,
wherein each of the one or more clamp members is configured to be selectively rotated about the longitudinal axis of the elongated shaft, so that the bone fixation pins are parallel to a different one of the at least two flat threaded side surfaces of the elongated shaft, wherein each clamp member includes:
a main body portion;
a clamping piece, wherein the main body portion and the clamping piece form a channel that is sized for receiving the threaded elongated shaft and releasably clamping on to the elongated shaft; and
a threaded nut provided at one end of the channel and rotatably engaging the main body, wherein the threaded nut is configured for threadably engaging the elongated shaft when the elongated shaft is clamped within the channel.
