Pisiform impingement after total wrist arthroplasty.

Author information

  • 1Department of Orthopaedics, Brown Medical School, Rhode Island Hospital, Providence, RI, USA.


We present a 64-year-old woman with rheumatoid arthritis who developed increasing pain 3 years after a total wrist arthroplasty. The pain was localized over the ulnar side of the wrist secondary to erosion of the pisiform. Pisiform excision resulted in a resolution of the symptoms. When placing a carpal component, which includes a base plate as part of its design, care should be taken to avoid any overhang of the implant edge into the pisotriquetral joint.
