Abstract

Hip arthroplasty is a common surgery, the success of which largely depends on its planning. Traditionally, arthroplasty planning performed on X-ray film, but this method has many shortcomings, including the well-known systematic repression for analogue X-ray systems to digital. The wide range of implant templates for the planning available in numerous of foreign special planning programs for arthroplasty, but all of them are very expensive. A team of authors from Sechenov First Moscow State Medical University, Lomonosov Moscow State University and Petrovsky National Research Centre of Surgery developed an original computer program for hip arthroplasty planning that allows to plan not only in the DICOM format, but also in photographs of traditional X-ray film. In the process of their work, it has been proved that the projection distortion when photographing X-ray applied to the X-ray viewer without a tripod is 1.95%. Practical testing of the planning program was carried out with 316 total hip arthroplasty surgeries. It turned out that for acetabular component the number of matches was 301 (95.3%), and for femoral components - 304 (96.2%). There were no cases of changing the type of components during surgeries. Thus, the created domestic import-substituting planning program allows working with a variety of image formats and making it possible to digitize X-ray film.
