Bone Fixator
Taylor Spatial Frame ( TSF ), 155mm ring with struts

Taylor Spatial Frame (1/2)

A Taylor Spatial Frame (TSF) [1] is the ring fixator introduced to the market by Smith and Nephew, Tennessee, USA, Figure 1. Its main structure is based on the Stewart-Gough platform [2, 3] and consist of two rings and six variable-length struts. The TSF's main application has been multiplanar deformity correction, although it is being used increasingly for fracture management.

A range of ring sizes defined by the internal diameter is available: 80, 105, 130, 155, 180, 205, 230, 255 & 300 mm. In addition, the rings come in five different shapes, Figure 2. The struts come in four length groups: extra short (75-96 mm), short (90-125 mm), medium (116-178 mm) and long (169-283 mm). They are connected to the rings at the manufacturer's predefined locations using shoulder bolts. Shoulder bolts allow strut rotation around their major axis, since shoulder height is greater than the ring thickness.

The choice of frame components is made by the surgeon and is based on the anatomy constraints and requirements of the injured limb. The connection between the TSF and the anatomy is established via ... continue reading on the next page...
