ABSTRACT:
An external fixator for securing a first bone portion in a fixed relationship with respect to a second bone portion. The fixator includes a bone screw clamping assembly for receiving a first bone screw which is connected to the first bone portion and which includes a spherical portion. The fixator further includes a bone screw clamping assembly which is operable to receive a second bone screw which is connected to the second bone portion and which has a spherical portion. The fixator also includes a connection member having a main body portion and an internal module adjustably mounted within the main body portion. The internal module receives a spherical end of one of the bone screw clamps and selectively permits universal movement thereof. The internal module may be linearly adjusted within the connection member independently in first and second directions which are substantially perpendicular to one another. The fixator further includes a locking mechanism for preventing universal movement of the spherical portion.
