How many screws per clamp should be used?
A minimum of two screws per clamp should be used. In the femur and tibia it is advisable in adults to use three screws per clamp to increase stability. In long term treatments, where there is a higher risk of bone screw infection or loosening, the use of three screws is an additional advantage. This is because the removal of one loose or infected bone screw will not prejudice the continued use of the fixator, and unnecessary surgery is avoided.
