A new cemented hip prosthesis was designed and clinically probed which takes into consideration the neckshaft angle variability. Femoral component with inclination angle of 125° was implanted in 22,64 % of patients, with angle 135° in 62,26 % cases, and 145° in 15,09 %. Follow-up results in 160 cases divided into three clinical groups showed mean Harris hip score in main group 84,94±2,28, whereas in two control groups 85,49±1,55 and 82,39±2,56. No statistically significant difference was found; however, mean age in the main clinical group was higher than in the control groups by 9,99 years and by 10,65 years, respectively (p<0,05). Therefore, regardless the fact that mean Harris hip score showed no significant difference in the three clinical groups while mean age in the main group was 10 years higher than in the control groups, conclusion about superiority of the designed prosthesis received indirect confirmation.
