Hydroxyapatite and revision of femoral hip prostheses
- 26 Downloads
Implants coated with hydroxyapatite (HA) are of very special importance in revisions of total hip prostheses. As far as the fernur is concerned, the rapid bony reconstruction due to the osteoconductive properties which ensure in particular the filling of defects of bony contact guarantee excellent secondary stabilization of the implants, provided that the mechanical assembly secured at operation be stable. The results of a personal series of 46 patients confirm the efficacity of the HA coating by demonstrating the quality of bony reconstruction and the long-term stability of the implants with satisfactory clinical results.
