Objective:
To report revision of BFX cementless press-fit stem loosening with a Kyon cementless stem and a head adaptor in two dogs.
Methods:
Total hip arthroplasty stem revision was performed in two dogs with loosening of a previously implanted Biomedtrix press-fit BFX stem. Both dogs had a well-integrated BFX cup and single stage revision was performed using a standard Kyon stem and a head adaptor in order to couple with a 17 mm head and maintain the BFX cup.
Results:
Revisions resulted in a stable functional prosthesis with successful bone integration at the one-year postoperative re-evaluation.
Conclusions:
Use of a Kyon stem with a head adaptor may be a successful option to provide immediate stem stability for revision of a loosened BFX stem with a properly osseointegrated cup.
