A NEW EXTERNAL FIXATION SYSTEM FOR TIBIAL SHAFT FRACTURES

In a new external fi xation system for tibial fractures, accurate reduction was achieved with a complex
temporary device, the Staffordshire Orthopaedic Reduction Machine (STORM) following which the fracture
was fi xed using a simple but mechanically sophisticated fi xator (IOS). The fi xator is designed to allow
controlled bending to optimise movement at the fracture site for callus growth. Ideal mechanical properties
are approached: elastic return is to the reduced position; epicentric placement minimises shear and distraction
on weightbearing; integral healing assessment measures bending stiffness. The device is single-use.
