✦ Synopsis

The in uiuo biocompatibihty of metals coated with several different types of ceramics [alumina (a-A1203), titanium oxide (TiOJ, titanium nitride (TIN), and hydroxyapatite (HAP)] was investigated. These composites had been devised for the purpose of incorporation into the stem of a total hip prosthe-sis. The materials were inserted into the mid-diaphyseal region of the femurs of adult dogs, and follow-up quantitative histological comparisons were performed for a period of up to 96 weeks. HAP-coated composites showed the best biocompatibility.

## Abstract We evaluated bone microhardness at the interface with hydroxyapatite‐coated stainless‐steel pins used in an external fracture fixation system. Pins were transversally inserted into the diaphyses of sheep tibiae and were loaded in for 6 weeks. Uncoated pins were implanted as controls. Mi
