Clinical results with the hydroxyapatite-coated Omnifit hip stem.

A 2-year follow-up from a prospective clinical trial investigation of the hydroxyapatite (HA)-coated Omnifit-HA Hip Stem is presented. Assessment of clinical and functional evaluation parameters demonstrates the excellent results obtained with the femoral stem. Radiographic observations indicate a complete lack of fibrous tissue in the HA-coated regions of the stem, thus promoting direct load transfer between the stem and bone. Comparison with published studies suggests that the clinical results obtained with the HA-coated Omnifit-HA Hip Stem compare favorably with the prior reports.
