ABSTRACT:
A clamping coupling for fixing of bone screws or pins, and connecting these bone screws or pins to an external fixator, includes an additional transverse clamping coupling to achieve better external-fixator anchorage when fractures extend up into the joint (condyle) of the femur. A selectively adjustable asymmetric arrangement permits fixed settings parallel to the longitudinal axis of the femur, while a lateral offset takes into account the natural lateral offset of the centerline of the condyle of the femur with respect to the longitudinal axis of the femur.
