ABSTRACT
A unique,
straight-stemmed, proximally porous-coated, modular hip replacement
system, coated with thin-film (5 to 9 microns) titanium-nitride-ceramic
was used clinically in 130 hip replacements in 117 patients
that were followed over a 2 to 12 year interval, mean 6.45
years. Harris Hip Scores demonstrated 82.3(%) excellent, 15.4
(%) good, 2.3 (%) fair and 0 (%) poor results. Thigh pain
limiting activities of daily living was seen in 0.8% (1/130)
hips. Kaplan-Meier Survival estimates using an end point of
revision of any component for any reason demonstrated an overall
survival of 95.5% in the 12-year interval. Cementless fixation
survivorship of the acetabular and femoral components was
98.5% in the 12-year interval.
