[A man with a curved deformity of the hand]. / Een man met een kromme hand.

ABSTRACT

A 63-year-old male was seen at the rheumatology outpatient clinic because of a curved deformity of his left hand, with fixed flexion of the MCP joints and hyperextension of the PIP and DIP joints. This so-called striatal hand, a feature of Parkinson's disease, can easily be confused with rheumatoid arthritis or Dupuytren's contracture.
