Abstract
In an attempt to circumvent the problems of loosening and adverse bone remodeling associated with metal femoral stems, carbon fiber composite femoral implants have been developed. A canine femoral implant was constructed with a carbon fiber core and braid and encased in a thermoplastic polysulfone. A proximal particulate hydroxylapatite coating was used in half of the implants, and the remainder were implanted as a press-fit composite stem. There were no clinical differences between the two groups. Positive bone remodeling responses were seen in both groups at fourteen months. Histological examination showed stable bone/implant interfaces in both groups with a propensity for more bone contact proximally in the HA-coated group. The uncoated implants produced a stable fibrous tissue interface with cortical bone maintenance suggesting constructive bone remodeling.
