Objectives-To evaluate patients with mutilans-like hand deformities in chronic inflammatory joint diseases and to determine radiographic scoring systems for arthritis mutilans (AM). Methods-A total of 52 patients with severe hand deformities were collected during 1997. A Larsen hand score of 0-110 was formed to describe destruction of the hand joints. Secondly, each ray of the hand was assessed individually by summing the Larsen grade of the wrist and the grades of the MCP and PIP joints. When the sum of these grades was > 13, the finger was considered to be mutilated. A mutilans hand score of 0-10 was formed according to the number of mutilans fingers. Surgical treatment and spontaneous fusions were recorded.
Results-The
