Summary:

Aim: to estimate functional status of coxarthrosis in patients requiring total hip replacement of the two hip joints. Material and methods. The biomechanical examination of 94 patients with bilateral primary coxarthrosis before and after total hip replacement was performed using clinical stabilometric software complex. The ability to perceive the mechanical load during standing and walking was evaluated at different stages of the treatment. The difference between the samples was estimated with the use of Mann — Whitney U-test. The rank correlation of biomechanical parameters was measured by Spearman coefficient. Results. It was revealed that the most responsive indicators are the transfer period, the first and second periods of double support and the deviation of the center of pressure relative to the average position in the frontal plane. Conclusion. After surgical treatment there was observed some improvement: the-left-and-right-step asymmetry decrease, rhythm rate increase, improved ability to maintain body balance, jog reactions increase.

Summary:

In the course of the study the foreign and native publications concerning total hip replacement have been analyzed. The data from National Registers of various countries are presented in the study. They highlight some issues upon total hip replacement, technologies of surgical intervention advancing and most important risk factors for endoprosthetic ball dislocation.
