X-RAY ASSESSMENT OF THE BONE TISSUE PERIPROSTHETIC REACTION AT THE STABLE FEMORAL COMPONENTS OF SLPS ENDOPROSTHESIS

Objectives. To study X-ray parameters of the bone remodeling around the stable femoral components of the hip joint cementless fixation endoprosthesis of SLPS system.
Methods. The analysis of 230 digital X-rays was performed with the average terms of observation composing 7 years after the hip endoprosthesis of SLPS system implanting with the presence of components stable fixation.
Results. It was established that bone tissue adaptation is characterized by the equable contact with the endoprosthesis surface with lack of resorption lines in 80, 9% of observations and the opposition bone growth in 97, 3%. Local areas of the prosthesis connection with the diaphysis cortical layer were revealed in 64, 3% cases and in 70, 3% of cases they were localized around the distal part of the component. Bone tissue growing into the porous titanium inserts were revealed in the form of parallel lines of the bone balks condensation in 98% of observations.
Conclusions. The research results testify to the efficacy of endoprosthesis of SLPS system in loading redistribution and periprosthetic bone tissue saving.
