The Taylor Spatial Frame (TSF) is an external fixator an shares a number of components and features of the Ilizarov apparatus The TSF is a hexapod device based on a Stewart platform and was invented by Dr Charles Taylor. The device consists of two TSF rings made of aluminium connected together by 6 struts. Each strut can be independently lengthened or shortened. Connected to a bone by wires or half pins, the attached bone can be manipulated in 6 axes (anterior/posterior, varus/valgus, lengthen/shorten.) Both angular deformities and translational deformities can be corrected with the TSF.
