Arthroplasty of the Hand: Radiographic Outcomes of Pyrolytic Carbon Proximal Interphalangeal and Metacarpophalangeal Joint Replacements

Abstract

Of the 47 pyrolytic carbon PIP and MCP implants, 14 (29.8%) required surgical revision or retrieval, mostly for extensor tendon contractures. Compared with the clinical survival of the implant, radiographic survival was poorer and did not correlate with clinical survival. Tilt of the proximal stem and subsidence were the more common radiographic complications.
