Abstract

Strain transfer near hydroxyapatite (HA) coated canine hip implants was examined using simulated anatomical loading based on in vivo strain measurements. Strain changes near implants relative to intact control values were in excess of 100% for transverse and principal strains for zero time period specimens. Cortical bone loss was noted in all implanted femora. Backscattered electron imaging along the HA-coated sections of the implants showed extensive bone bonded to the coating. Implant surfaces were examined by normal light, ultraviolet light microscopy and histomorphometry.
