Subcutaneous tendon rupture of extensor tendons on bilateral wrists associated with calcium pyrophosphate dihydrate crystal deposition disease

Abstract

Calcium pyrophosphate dihydrate (CPPD) crystal deposition disease is a well-recognized inflammatory joint disorder. Extensor tendon rupture associated with CPPD deposition has rarely been described. We report herein the case of a 58-year-old woman who underwent reconstruction for subcutaneous extensor tendon ruptures of the extensor tendons for the ring and little fingers on both wrists associated with CPPD deposition. The significance of this case is the occurrence at an earlier age compared to previous papers and the appearance on bilateral wrists.

Key words::

• Arthropathy
• Calcium pyrophosphate dihydrate (CPPD)
• Tendon rupture
• Tophaceous deposition
• Wrist
