The radiographs of the hands demonstrate the presence of marked erosive changes at the PIP joint of the left index finger.
The erosive changes are characterized by subchondral central erosion at the heads of the proximal phalanx with marginal osteophytes involving the middle phalangeal base (gull-wing appearance), diffuse cartilage loss and joint space narrowing.
From the case:
Erosive osteoarthritis - gull-wing appearance
