In tension band wiring different tensioners and wire-connections are in use. Both of these were examined on tensile force during and after connection with help of a material-testing machine. Additionally the different connections were examined under traction-load. ⋯ Further stretching causes plastic, i.e. irreversible deformation in monofilament wire and its connections. In twisted wires further tension stress causes ruptures especially at the border of the fixation clamp. In conclusion extreme active exercise of fractures treated with tension band wiring should not be emphasized.
