Popis: Aim – to conduct a comparative assessment of the accuracy of the developed method of preoperative planning for primary hip arthroplasty. Material and methods. The "Method of preoperative planning in hip arthroplasty" and special device were developed to improve the accuracy of preoperative planning and reduce the number of complications. A clinical study was conducted in the comparison groups. In the main group (50 patients), we used the proposed method in the pre-operative planning; in the control group the patients were prepared for the operation using a standard planning method. The accuracy of evaluation of implant sizes, limb length and offset were registered in the post-operative period. The preoperative planning data were compared with the results obtained. Results. The accuracy of offset estimation in the main group was higher than in the control group (T-criterion = -2.6; p = 0.01). The average difference between the estimated offset and the one obtained in the main group was 1.4±1.5 mm, in the control group it was 2.2±1.7 mm. The error in head size estimation in the main group was less than in the control group (odds ratio = 3.02). No significant differences were registered in determining the size of components of the endoprosthesis, and there were no differences in the leg length in the study groups. Conclusion. The developed method allows for improving the accuracy of preoperative planning in hip arthroplasty. The proposed device ensures the correct placement of patients when performing pelvic radiography, and also makes it easy to change it when performing this procedure.
