The Full Form of TBW is Tension Band Wiring.

The philosophy behind the tension band for the olecranon is that it converts tensile forces on the posterior side of the olecranon into compression forces at the joint line during flexion. The fixation is simple and inexpensive and works well if executed properly.

Multifragmentary fractures cannot be fixed with a tension band. In order to be able to use a tension band, the anterior (far) cortex cannot be comminuted and must provide a buttress to allow compression.

Choose a wire of sufficient strength to withstand the tensile forces generated in the figure-of-eight loop (1.0 mm). Positioning the K-wires as close to the joint while also penetrating the volar cortex is paramount.
