Implant resection arthroplasty in the treatment of Kienböck's disease.

The lunate implant acts as an articulating spacer to maintain the carpal bones relationship after a resection procedure. Its use helps preserve functional wrist mobility and stability. Our experience spans 25 years and the use of three materials. Since 1986, we have used lunate implants made of unalloyed titanium with very promising results. This procedure requires strict surgical indications, an exacting technique, associated intercarpal bone fusions as indicated, and the avoidance of abusive activity.
