Abstract
Arthroplasty of the metacarpophalangeal (MCP) joints for inflammatory arthritis can be performed using silicone implants with or without metal grommets. Titanium metal grommets were introduced in 1987 for MCP joint arthroplasty and theoretically protect the silicone implant from fracture and fragmentation [15, 16, 18, 20–22]. We found two reports of particulate metal debris associated with silicone implants with grommets leading to a robust tissue reaction [9, 25]. In contrast, metallosis from hip and knee arthroplasty has been frequently reported [7, 8, 11, 24, 26]. Herein we present a patient with rheumatoid arthritis who developed metallosis following MCP arthroplasties with grommets.
