Investigation of the torque-tension characteristics of a flanged external fixator pin.


:The torque-tension characteristics of standard, conical and flanged external fixator pins and a cortical screw were compared using a commercially available testing apparatus. The flanged pin and the screw were similar in behaviour, and converted torque into tension more efficiently than conical and standard external fixator pins.
