title: An overview of first metatarsophalangeal joint implant arthroplasty.
abstract: The metatarsophalangeal joint of the great toe often requires an arthroplasty to correct joint disease and pain. Today, joint replacement systems are combinations of components manufactured to optimize biological ingrowth, mechanical interlock, press fit, and cementing. Three different types of arthroplasties are available to foot surgeons: the double stem hinged silicone implant, the two-component joint mimicking implant, and a hemi-implant available for the phalanx. No comprehensive studies on very large populations have been conducted to accurately evaluate the beneficial long-term effects of these implants. This review article describes the development of the toe arthroplasty, details the commercially available implants, and addresses the advantages and adverse effects of each implant.
