PolyWare compares patient x-ray images to measure the volume of polyethylene material that is worn away from the bearing surfaces of orthopedic hip implants, over time.

The amount of wear is determined by precise 3D measurements from standard patient radiographs. This data is extremely useful for determining the longevity of bearing materials, the quality of implant design, and even when future revision surgery may be required.


Product History

In 1993 Dr. Peter Devane, of Wellington, New Zealand, developed a new three-dimensional technique for the measurement of polyethylene wear in metal-backed acetabular components. Using a back-lit digitizing tablet, points from Anteroposterior and Lateral radiographs were captured by special software. Using AutoCADŽ software, and some custom programming, this data created three-dimensional solid models of the prosthesis. The model was rotated to a standard frontal view, and femoral head displacement and the volume of polyethylene was recorded.

In 1995, Dr. Devane and Dr. Robert Bourne approached DePuy regarding development of a user friendly package that would incorporate Dr. Devane's program into a Microsoft Windows environment. Due to its proximity to the heart of the orthopedic industry (Warsaw, Indiana) and its ties with the industry, Draftware Inc was hired to develop Dr. Devane's software. Within one year, nine centers in U.S. were using the new software to measure polyethylene wear in 950 cases.

In early 1997, Dr. Devane and Dr. G. Horne improved the accuracy of the software to +/- 0.028 MM by minimizing user input and analyzing digital images of clinical radiographs scanned into a personal computer. In October 1997, Draftware Inc announced the official release of the PolyWare Pro 3D product for Microsoft Windows.

In 2005 the accuracy of PolyWare was again improved with new software imaging technology. The new software algorithms removed user input error by automatically finding the edges of the orthopedic implant in the image data. The improved software was released as PolyWare Auto in 2005.
