Diagnosis

Plain hand radiographs typically show marked ulnar subluxation and deviation at the metacarpophalangeal joints. Absence of erosions is a notable feature, although occasionally "hook" erosions may be observed, which are similar to those seen in SLE and ankylosing spondylitis. Evidence of muscle (soft tissue) atrophy also may be present.


Treatment

The focus of treatment is toward alleviating pain and maintaining functionality of the affected joints through use of
nonsteroidal anti-inflammatory drug Non-steroidal anti-inflammatory drugs (NSAID) are members of a therapeutic drug class which reduces pain, decreases inflammation, decreases fever, and prevents blood clots. Side effects depend on the specific drug, its dose and duration of ...
