Abstract
Accurate in vitro evaluation of the efficacy of spinal instrumentation devices requires specialized equipment. A displacement transducer that directly measures motion at the fracture site has been designed. Data are processed on-line by computer. Tests using an earlier photographic technique simultaneously with the transducer show the new method to be more accurate and reliable and the results more readily available. Application of the transducer for monitoring fracture creation and end-cap purchase is also shown.
