Summary
The diaphyseal anchorage of the Kotz Modular Femur and Tibia Reconstruction (KMFTR) System, made of cobalt base alloy with integrally cast beads upon the intramedullary shaft and two paracortical flanges for screw fixation, can be stabilized on long bones without using cement. Implants retrieved up to 36 months after implantation in a clinically stable or loosened condition were investigated histomorphologically. The primary stability is based upon an intramedullary press-fit and screw fixation of the flanges. Secondarily, bone ongrowth to the implant and ingrowth occurred at many locations. Nevertheless, vascular damage, adverse cellular reactions to the implant material, and nonphysiological stress distribution must be regarded as risk factors for long-term anchorage.
