When finger metacarpophalangeal (MP) joint arthrosis exists, it is indeed infrequent that implant arthroplasty is not the most optimal treatment alternative. In the setting of post-traumatic or postinfectious disease at the MP joint, however, implant arthroplasty is con-traindicated; thus alternative techniques of restoring pain-free function become relevant. Despite the limited roles of resection arthroplasty and arthrodesis, these techniques can restore useful function. So long as the MP joint is pain free and relatively stable, most patterns of functional prehension can be maintained. Indications and technical fundamentals of resection arthroplasty and arthrodesis are addressed in this article.
